I'm saying it right up front. This video goes above and beyond shortblock rebuild parts for a reason. Read on... The first part is stern, the last part is happy.
Nobody in their right, left, forward or reverse minds puts a 23-year-old 4g63 engine back together with 100% OEM parts. Nobody's shooting for that good ol' stock 190hp feeling with a DSM drivetrain. Nobody. Not unless they've got something to prove.
I am putting a 7-bolt head on a 6-bolt block. So with that said, I show several over-the-top internal parts that are and are not related to the short block itself. I show cams and valve springs which only matter for head work. Not part of the short block. Nobody makes an engine gasket kit with all the parts mixed and matched to do this. So what people have to do is order both kits, or order all the individual parts separately like I am doing here.
It's at this stage you are working with a machine shop to return your old worn-out block to the specs you've chosen to follow, and you need these cylinder head parts at this stage of the game to do it right. These parts making an appearance in this video show 3 things... 1) I am not aiming for a stock build 2) Now is the time to have your cam and valve springs if you're going to make any changes to the head. 3) these gaskets, seals, pins, bolts and bearings are things you will need no matter what it is you're building if it's a 6-bolt block. When I do the head series, I will be showing modifications and parts to rebuild and make a 7-bolt head fit a 6-bolt block.
This video assumes you disassembled a running or freshly-broken engine and that YOU HAVE ALL THE BOLTS, NUTS, WASHERS, and HARD PARTS of the motor that it needs, bagged and tagged like was demonstrated in the "Crankwalked?" video. You've watched me clean and inspect valves, lifters, rockers, crankshafts, rods, etc. I don't need my turbo, hoses, vacuum lines or anything like that yet, and they likely won't be for a MHI turbo anyway. This video focuses on the gaskets, seals, bearings, consumable and disposable parts that you should replace for the shortblock only. My old trusty 6-bolt front case is coming up in a future video, getting refurbished and rebuilt, and ssembling a shortblock doesn't require having timing components yet. The head gasket will probably get its very own video just like the front case.
As you can see, I have very big plans with this upcoming series. We've hit the 200's on engine stuff. It's a milestone.
For you 7-bolt guys... bah! I know this is all 6-bolt part numbers. Some parts are interchangeable but I didn't make it clear which ones are in this video. Don't worry, you will need these part numbers eventually (I hope that was a joke). But if you wait long enough, perhaps I'll be re-assembling a 7-bolt again? Here comes the first bit of good news...
The reason the "Crankwalked?" video had a question mark in the title is because I wanted to see others' comments about it. Gain a consensus. There are so many different opinions about shortblock failures on the 2g cars that I didn't want to take sides with such an entertaining video. But it's not crankwalked. What you see is rod bearing failure as a result of torsional stress on the crankshaft. It was caused by a catastrophic clutch failure. The thrust bearing was .014", and crankwalk cars that fail from crankwalk are usually around .075"-.150". My thrust bearing was beat to death as my old 6-puck fragged. All the fail was initiated by the drivetrain, and the drivetrain problem was a fail by yours truly that had repeated several times prior to me making videos about it and getting it right. It's my fault for not catching it, but when I discovered it, the drivetrain series was born. So my 7-bolt crank is trashed, but the mains are fine. New bearings and a crank would fix its thrust measurements and I may just rebuild it for the sake of a video someday.
Now comes the really good news. My brother is working with me to build a website. There will be tech links and things that simply can't be delivered on YouTube. Not in a practical and effective way anyway. Things like schedules, projects and mod lists, parts lists, bolt lists, torque specifications, printable worksheets for blueprinting, the parts I used to make my fuel injector cleaner... stuff my viewers need or ask for. Soon you'll know where to find it. I need to learn how to maintain it, but I'm a good student. Still, these things take time, and I haven't yet wrapped my own brain around its potential. I'm putting it out there for you guys because you deserve it. I'm simply astonished at how the channel has grown, and I feel the need to give back.
Jafro's GSX Build Parts - 1gina2g
Some advice and expectations about the parts acquisition process. Cars
only get built in a week on TV. And still then you have to take their word
for it. The ones that actually do it have a 20 man full-time crew, and
therefore; they have no excuse for not having it done yet.
We don't have that. Stuff takes time. I'm not building a car to sell it.
There's a whole lot of parts in this video. Whole lot of parts. Rather
than spend a ton of space babbling incessantly, this is what you came here
for. Part numbers. Meat. This isn't an all-inclusive list of parts for a
rebuild. It's what YouTube let me fit. I hope you find what you needed.
If not, hang tight. Help is on the way.

4g63 Block Oil Gallery Mod
This modification is intended to improve your 4g series engine's oil
delivery. People frequently discover large chunks of flash in their
engine's main oil gallery. It's because the galleries are part of the
cast, they're not machined into the block. There is also a very rough
sharp edge where the main oil gallery is bored into the block, and oil must
make a slightly greater-than 90° turn in order to begin its course to the
parts it lubricates. Both of these conditions cause turbulence in the oil
flow. My goal in this video is to eliminate as much of that as I can.
This is a cheap and easy modification if you have the tools, and the
patience. Any engine with cast-in oil galleries could probably benefit
from this. Be careful not to cut into the high pressure oil gallery or
else you will circulate un-filtered oil to the #1 main, oil pump, and rear
balance shaft. You will also deprive the rest of the engine the oil
pressure it needs to operate. So in short, punch a hole in that and it's
trash. I did this my way, everyone may choose to do this a different way.
I just wanted to make this video to raise awareness.
Also, there's a great thread on DSMtuners about this. Pictures and
everything. Written by a machinist and friend of the DSM community. Go
give him some reps because he's posted a lot of great info about the DSM
oil system over the years.
6&7-Bolt 4g63 Front Case & Oil Pump Rebuild
Here we disassemble, clean, inspect and rebuild both popular 4g63 front
cases. This is not difficult, you just need to know what to look for.
Something else that happens in this video is the analysis of one of the
factors that caused my 7-bolt engine to fail. It wasn't the only cause,
and we'll talk about that later, but left to its own devices and without
the other contributing factors, it would have been the only cause.
Cylinder Head 201 - Radius Cut Valve Job
This video covers the complete valve job process that your machinist might
perform. If the 100 series videos didn't help you identify and correct a
problem with your cylinder head, then this is the next step. This video is
brought to you with permission from my machinist in full 1080HD, and covers
cleaning up the head inside and out, preparation and setting up a radius
cutter, cutting all 16 valve seats, valve grinding, and spans 3.5 hours of
actual work in under 30 minutes. There's nothing like this anywhere else
THANK YOU BALLOS PRECISION MACHINE. Thank you for the professional
explanation and execution of a job excellently-done, and un-precedented
access to your facilities.
A valve job is done by re-grinding or replacing valves, and then having new
seats cut to match the faces of the valves you're using. There are several
different machines that might be utilized to achieve this result, but the
process is the same no matter how it's done. There are seat cutters that
utilize cutting stones. There are valve seat cutters with 3 separate
angles installed 120° out-of-phase, and there are single cutters with all
3 angles (radius cutter) that cut with one blade in one pass. The machine
demonstrated here is a Sunnen VGS-20 Radius Cutter. This machine (now out
of production) produces a gradual curved seat that's superior to the shape
of a traditional 3-angle seat. While a radius cutter does contain the 30,
45 and 60 degree angles, it does so without leaving any sharp edges between
My valve selection includes Supertech 1mm oversized nitride-coated
stainless steel undercut and back-cut intake valves, and 1mm oversized
Inconel back-cut Exhaust valves.
Inconel is a high-temperature alloy utilized in marine and forced-induction
performance engines that can handle more abuse than steel can without
melting. The other characteristics of the valves which are discussed
typically yield bigger gains in airflow than simply using a bigger hole and
a bigger valve.
Why I did this to a perfectly-good cylinder head:
I changed cams. Because the valves were previously recessed during another
valve job 9 years ago, my valve installed height was increased and this
raised the operating positions of my rocker arms. My new camshaft
selection dictates using the stock valve install height. The only
solutions to this valve install height problem are to either replace the
valve seats, or install oversized valves. I opted for the latter.

Good luck finding info about this using Hyundai and Kia in searches.
Wikipedia doesn't have any info about it grouped with the Sonatas either.
There is no question what this is, well illustrated in this video.
I apologize for the length of this video, but a lot of ground is covered in
a short time. Hopefully there's some information in here you may someday
use. I'm just trying to expose it because there doesn't seem to be any
real information floating around in the forums about this yet.
The car is a first-generation 1999-2005 Kia Optima sedan. It has the EVO
equivalent of a 4g64 2.4L. Before using any of these parts, do your
research, cross-reference your parts and know what you're getting into.
Using parts from this rotating assembly in a 2g Eclipse will require
aftermarket rods and/or custom pistons. This is information for those who
wish to frankenstein their builds, or save a buck... whichever.... either
one of those requires skill.
4g63 Balance Shaft Elimination - bearing modification
This is the first part of a two part series about balance shaft elimination
on 4g series engines. This video details the bearings, the other video
will cover the front case modifications. I've already got a low-def video
of the front case mods, and I plan to re-shoot that one in HD when I'm in
the assembly phase. It's linked in the video.
The balance shafts are designed to cancel out harmonic vibrations caused by
combustion and the spinning rotating assembly. They may offer a greater
degree of comfort to the driver and passengers, but with that comfort comes
Often, when a 4g63 timing belt gives up, it's because the balance shaft
belt breaks or comes loose and takes the timing belt out with it. When
that happens, it can total your pistons, valves, damage the crankshaft,
wrist pins, timing belt tensioner and crank angle sensor. Basically, it
can total your motor. The balance shafts also have a combined weigh over
10 lbs and both are driven off the timing belt making them additional and
heavy rotating mass. If you've got a lightweight flywheel but still have
balance shafts, you have your priorities mixed up.
So here's what you do with the bearings. It's easy. You can do this at
home. You CAN do it with the motor in the car, BUT DON'T. You must enjoy
punishment to do this like that.
The end result will slightly increase your oil pressure, but usually not
enough to cause concern unless you have a full-circumference bearing turbo, ball bearing turbo--with your oil feed coming off the oil
filter housing. The head feed would be better in that case because it's
regulated at 15 PSI.

4g63 Timing Belt Parts
I don't care which DOHC 4g63 you've got. This is the video for you. All
the parts and tools necessary to do the job right, right here.
I know some people will ask about aftermarket timing kits. I'm not a fan.
There are some things you can not skimp on. IMO, anyone using aftermarket
parts on an interference engine have put the cart in front of the horse.
Interference engines are engines whose pistons and valves share the same
space at different parts of the strokes. If the timing belt (which is
responsible for preventing them from doing that at the same time) breaks,
or a pulley seizes up, then what follows goes something like this...
"Hi piston, I'm valve", valve said.
"Oh hey there, valve... Who's your friend that I just stepped on there?",
said the piston to the valve.
"Oh, her? That's my wife, and now she's a little bent out of shape now.",
"I brought my whole crew, and they're next door introducing themselves to
the rest of your friends.", piston uttered matter-of-factly.
"So I hear. It sounds like they're done already.", said valve.
"Yep, I'm afraid we are, too. Sorry about your wife there..."
Aside from damage to pistons and valves, it can crack guides, damage rods
and wrist pins, crank bearings, you name it. Worst case is when the valve
face breaks off and chews up the cylinder head. No valve job will ever fix

Cylinder Head 205 - Degree DOHC Camshafts
This video is all about establishing your valve timing baseline, and
adjusting your camshafts to the manufacturer's spec. It's only ONE of
several steps that should be performed when you're assembling your engine
on an engine stand. Establishing these conditions with accuracy while your
engine installed in the car is a near-impossibility, and the reason why...
is demonstrated in this video. There are several challenges to overcome
when performing these procedures on a 4gxx series Mitsubishi engine, and
they're all defeated here.
The cylinder head used in this video is a J1 spec '92 Hyundai Elantra
small-combustion chamber head which has had several valve jobs and has been
resurfaced multiple times by budget engine remanufacturers who didn't care
about quality control, as well as performance shops who do. It has had no
less than .040" removed from the head gasket surface, the valves are
recessed because of all the valve jobs performed, and at some point when it
was cut, it wasn't level. Removing material from the deck surface will
change the installed camshaft centerline, and that will change your
engine's valve timing events even if all other parts remain the same.
I would claim this is a multi-part video except that I've got the videos
broken up by topic already, and this one is all about setting your cams to
the manufacturer's specification. It is not the end of testing that will
be performed with these tools. The basics concerning the process and tool
fabrication are covered here. Further discussion on this topic concerning
the effects of advancing or retarding camshafts from spec, and for checking
your valve clearance will be in the videos that follow. I had to end this
video after the manufacturer's spec was achieved to make it easier to
digest, and because it would have created a video greater than one hour in
length despite the break-neck speeds that things happen here on
Where your cams are set determine how the swept volume of the combustion
chamber gets used. The information on the manufacturer's spec sheet is
their recommendation for baseline settings that will help you get the most
out of those camshafts. Whether or not your engine can operate with those
specifications without additional hardware or without causing a
catastrophic failure will be expanded upon in Cylinder Head 206. The next
video should be used as a companion to this video because establishing the
manufacturer's baseline is not the end of the assembly or testing process.
It's only half the battle. Should you be lucky enough to find your
combination of parts allow your camshafts to fit and requires no additional
adjustment after assembly, the steps in this video and in Cylinder Head 206
should still be performed if you are doing the assembly yourself. Failure
to inspect these variables may lead to a tuning nightmare once the engine
is back in the car, hard starts, or worse... bent valves and damaged wrist
Making these tools and performing these steps will give you the peace of
mind to know with certainty that your engine is operating safely at its
Cylinder Head 107 - 4G63 HLA Lifter Tech
I have all 3 revisions of the DSM lifters in this video. This will help
you identify which ones are in your cylinder head, as well as illustrate
the cleaning process, and each lifters' advantages and disadvantages.
WHEN you finally have to perform maintenance on these lifters, they're a
bigger pain than a solid lift valvetrain is (ONCE). BUT if you follow the
service schedule on a solid lift valvetrain, HLA's are a smaller pain
You'll never need feeler gauges to adjust these hydraulic lifters, and
you'll never need to know their gap. You can't adjust them. You'll just
know whether or not they're good by the amount of noise they make. 3
things can cause trouble with them. Clogged lifters, insufficient oil
pressure, or insufficient oil volume.
So before you sail your oil pump down the river, you can follow the steps
in this video to rule out the first variable. You can actually remove and
re-install them without taking the timing belt or camshafts out, but that
will be another video. Chances are you already know this. The second and
third potential issues COULD be your oil pump, but for your oil light isn't
on and if there's ever been machine work in its past history to either the
head or the block, I explain in "Cylinder Head 103 - Deck Tech" what a
frequently-overlooked part of the cylinder head is that could be a
contributor to the issue. That link is in the video.
I MENTIONED ANOTHER COOL VIDEO: it was here...
Thank that author as well. He did a great job! I don't know the guy and
claim no credit to his work, I'm just giving him a shout-out.
Blueprint 102 - Measuring 4g63 Crankshaft Endplay
4g63's are famous for hosing crankshaft thrust bearings. This video
illustrates the process of how to check the thrust bearing clearance
whether the motor's in the car or not. Of course in my case the motor's on
a stand for this video. Lucky for me!
In cases where the engine is still in the car, the same procedures can be
used so long as the indicator is attached to the engine block. The plunger
can be set up touching either the inside of the crank pulley or by removing
the clutch cover plate and contacting the flywheel.
What the thrust bearing does, is prevent the crankshaft from having lateral
movement in the main bearings. If a crankshaft develops excessive movement
here, clutch engagement and hydraulic problems will begin showing up,
followed shortly thereafter by catastrophic failure of main bearings, rod
bearings, connecting rod failures, oil pressure problems, or even broken
blocks, crankshafts and rods in extreme cases. It's important that every
4g63 turbo engine is within spec on this
When the crankshaft aggressively wears through the thrust bearing
developing lateral play, this is called "crankwalk". On some block
castings, replacing the bearings will NOT fix the problem. An engine block
that is prone to crankwalking can not be fixed. The only option in these
cases is to replace the shortblock and rotating assembly with new or used
parts that are stronger than the one you've unfortunately encountered. For
the 2g guys, the best option for repairing this problem is to remove the
7-bolt turbo shortblock your car came
with and replace it with a 6-bolt from a 89-92.5 production date turbo DSM. Non-turbo blocks CAN be used; however, the block will
not have oil squirters that aim towards the back of the pistons. That
stream of oil aides lubrication to the wrist pins, cylinder bores, and
somewhat cools the pistons. All good things on a turbo setup. Aside from that difference, there
are no other differences between the non-turbo and turbo
blocks. The pistons and thus the compression ratios are different, but
that's it. Oil squirters can be machined into the main galleries of a
non-turbo block, but it's more trouble
than it's worth unless you can't find a turbo block.
There are tons of differing theories about what causes crankwalk. Nearly
all of them are plausible and logical arguments. I will not get into those
debates in this video in order to focus on procedures for testing and
replacement. Please feel free to google "crankwalk 4g63" and read the
volumes of information available already. The arguments and gathered data
are older than the Eclipse itself and in abundant supply on the internets.
Magnus, RRE, VFAQ, and many other parts vendors have lengthy write-ups on
their own research and development. The bottom line is that the 6-bolt
shortblocks are LESS likely to suffer from this.
Next time you see someone with a video that looks like it was shot with a
potato asking "does this sound like crankwalk", you can send them this
video. There's a reason for every noise, rather than focus on the sound,
focus on eliminating the real problem. KNOW if it's out of spec.
Hyundai Assembly 6 - Manifolds & Turbo
I love music videos. They're so much easier to narrate. I don't want to
upset anyone by not providing commentary about what I'm doing or where this
build is going... and this is the video where all that stuff comes
together. Quite frankly, I missed you. I really enjoy these little talks
In this video is a little fabrication, maintenance, comparison and
assembly. Un-boxings, cleanup, break-fix... Variety! You know... The
stuff that keeps happening as you wrap up any build. It's not a longblock
until it has manifolds, and a turbo
build has a few more things than just that in order to make it complete.
My attention has now turned towards preparing the chassis and accessories
for installation and I promise there will be more involved videos following
this one for the hardcore auto techs. Whether you're watching or wrenching
on this one, all this stage does is create anxiety for wanting to hurry up
and finish the install, but don't rush. Do it right!
These are the non-reusable parts for the turbo install. ALL of the other part numbers in
the video were shown:
MF241255 x2 Oil Drain Bolts (upper)
MF101229 x2 Oil Drain Bolts (lower)
MF660031 x2 Oil Drain Gasket (washer)
MR258477 x2 Oil Drain Gasket (flange)
MF660064 x2 Oil Feed Crush Washer (turbo)
MF660063 x2 Oil Feed Crush Washer (head)
MF660065 x4 Coolant Crush Washer (turbo)
MD132656 x4 turbo Bolt (M10 x 80 x
MD132933 x8 turbo Spring Washers
Thank you all for keeping up with this build. Thanks especially for the
kind comments and interest in this project! You guys are the best!
Glyptal Application Process
In this video I detail the application process of a popular crankcase
coating... that is... if crankcase coatings are actually popular.
In this video, 98 coffee filters gave up the ghost. 238 q-tips paid the
ultimate sacrifice. Almost a dozen brushes were executed, and 3 aerosol
caps dispatched to their graves. Also, during the battle, several Dremel
tools were maimed, one severely.
Look, I'm doing everything I can to liven this topic up and make it
interesting. Cleaning and painting are about the least interesting things
someone else can watch. It's absolutely painful to edit, I know that much.
It's not so bad for the guy doing the actual painting, but I'm doing my
best to keep people's attention.
This is a full month's work in a half hour. I had to space the job out
because of my filming environment and the toxicity of materials I was
working with. Take my warnings and advice in the video seriously. They're
the words of someone who's done the job. They help set expectations.
The most useful thing I can do is post links to other discussions that have
already occurred, and to make room for places where people have posted
their experience with failures of engine coatings. Despite my searching, I
can not find any pictures or video. I found ONE plausible description of
the kind of failure that can occur with improper application, but it was
still a third-hand report. There are fans of this product posting in these
threads. If you are considering this treatment, WEIGH THE PROS & CONS FOR
YOUR BUILD, and YOUR HEALTH. Don't do this just because I did it.
So until anyone provides photo or video evidence, here are the links to
threads where it was discussed. This google search is mean. It's too
direct and to-the-point. It might hurt somebody's feelings? Yes, I've
read them all.
Hyundai 4g63 Assembly Part 3
I have bad news. The big camera's playback heads bit the dust from
extensive prolonged use. I wore out the tape drive. No manner of cleaning
tapes can fix what it's been through. I've talked many times about how
much footage goes into one of my 15 to 30 minute videos, and for every hour
of video footage I've shot, the camera does double-duty because after
shooting, it has to be played back in real time during capture. I've done
more than 130 videos this way, probably over 2000 hours of use in the
harshest of environments, and it just couldn't handle it any longer. I
shot several more tapes beyond what's in this video that I can't even
import because the play heads failed. I don't know if any of that video
even stuck to the tapes?
The lost footage from the last video was an early and un-recognized sign of
what was soon to come. I know I joked about it, but in reality it's really
not very funny at all. I can't afford a backup for a piece of equipment
like this, so it's something I don't have. As bad as this news might feel
to you, I feel it 21,000 times over and I mean that. This couldn't come at
a worse time and expense for me, and at a point where my production was
really starting to wrap up on this project to move on to bigger and better
things. It's the only camera I have that can do what I do here on this
channel, so I'm forced to stop production for now.
Even though my camera is huge, 7 year old HDV technology, these things
still sell for several thousand dollars used because they record
un-compressed video unlike every other flash storage based solution
available at twice the price. 3CCD 1080/60i HD cameras that shoot to tape
have advantages that you can't affordably achieve with solid-state media.
I have to use un-compressed footage to do what I do here or else there's
nothing left of the video quality after 7 exports and a final mpeg
compression. The Sony Action Cam can't do it, we learned that in a
previous test video. Even if it could, it can't do close-ups and
everything's fisheyed. Buying a low-end 4K camera is impractical because I
can't efficiently or effectively edit that video without a $9,000 computer.
Jafromobile is just not that big of a channel, and I do this completely
un-sponsored and at my own expense with the help of a handful of friends
who volunteer their talent, time and information. It's the epitome of
low-budget and what it earns still doesn't come close covering the
channel's equipment and expenses as they occur.
People have urged that I do a kickstarter, but I can't bring myself to ask
for that from the community. I don't sell a product or offer services so
there is no profit margin. I can't accept money for something that happens
only at the speed of my available resources. To me, this channel is my
proverbial gift horse to all of you.
I know what you're thinking and I realize this is a grim conclusion to this
video. It sounds like I'm down for the count, but don't rush to the down
vote button just yet. As of the upload date of this video, I'm paying out
of pocket to fix a ridiculously expensive 3CCD 1080HD broadcast quality
video camera so that these projects can resume, and so that I can bring the
final assembly steps to you in the same quality you've grown used to seeing
here on Jafromobile.
If I wear out a camera every 3 years, then so be it. This is love, and no
expense is too great. The big camera is being fixed by its manufacturer,
and I'm expecting the repair to cost as much as replacing it. I sincerely
hope that's not the case. Hopefully my production only has to take a short
break. Once production resumes and I can import these tapes, I've got some
really awesome stuff coming up and I hope every last one of you is here to
see it. I may have a few other backlogged nuggets I can upload, and as
always I'm happy to discuss this in the comments and provide updates on the
repair as I get them.
Update: Awaiting quote due by 5/16 according to the repair agreement.

5/12/2014 - Repair paid in full $440. Far less than I was expecting. I'm
glad they still make parts for 7 year old professional equipment. Thank
You Canon, USA! Repair should be complete within 7 business days from
receipt of payment. The quote only took them 24 hours and they quoted a
week just for the estimate, so at this rate I should be back up and running
once again very soon. Thank ALL of you for your kind words, HUGE
generosity, and all of the moral support. I swear I have the best
subscribers on YouTube!
