Now this is a story all about how
My bearings got flipped-turned upside down
And I'd like to take a minute just sit right there
And tell you how I used to mix and burn my gas and my air.
In RVA suburbs born and raised
On the dragstrip is where I spent most of my days
Chillin out, maxin, relaxing all cool,
'n all shooting some BS outside with my tools
When a couple of guys who were up to no good
Started running races in my neighborhood
I heard one little knock and my rods got scared
And said "You put it in the garage until you figure out where..."
I Begged and pleaded that it not be that way,
But it didn't want to start and run another day.
I kissed it goodbye, because the motor punched its ticket
I got out my camera, said "I might as well kick it."
Crankwalk yo this is bad
Drinking metal shavings from an oil pan.
Is this what the rumor of crankwalk is like?
Hmm this won't be alright
But wait I heard knocking, grinding and all that
Is this the type of failure that should happen to this cool cat?
I don't think so, I'll see when I get there
I hope they're prepared for this video I share.
Well I pulled all the bolts and when I came out
There were chunks in my fluids in the pan and they drained out
I aint all depressed cause I seen this before.
I got my books and my wrench and we'll do it once more.
I sprang into action like lightning disassembled
I whistled while I worked and my hands never trembled
If anything you could say that this bling is rare,
and when I saw what broke I stained my underwear.
I turned off the air compressor 'bout 7 or 8
And I yelled to crankcase "Yo holmes, smell ya later"
I looked at my internals they were finally there
To sit on my workbench and stink up the air.

Here's the 48,000 mile-old 7-bolt I blew up summer 2011 after over 150 drag passes, a half dozen Dyno sessions, 4 transmissions, 3 clutches and 10 years of hard all-weather use.
7-Bolt Shortblock Failure - Full Diagnosis
If you are your own mechanic, there is no more important character trait
worthy of development than the ability to own your mistakes. That's where
the line is drawn between good mechanics and bad mechanics. It's not the
failures but how they deal with them that measures their ability.
In short, it's not easy to admit you did something wrong or were negligent.
But if you don't own it and talk about it, it doesn't get fixed, and
nothing positive can come from it. It was my quest to overcome my clutch
issue that lead to the creation of a video. That video is the textbook
perfect guide for how to correctly install a DSM transmission.
Crankwalk as described is caused by a casting defect. This was not a
defect. This was preventable. A lot of people would find something like
this and not tell anyone out of embarrassment. I'm not ashamed. It's my
fault. I got good use out of this engine and it was tough enough to make
it 48K miles since the last rebuild despite my abuse. I'm here to tell you
if you bought a used car that's had its clutch replaced, or if you ever pay
someone else to do it... make sure it has this bolt. It's stashed away
between the starter and the transfer case, so it's hard to see. Make sure
all of your bell housing bolts are torqued properly because fastener
problems can destroy your shortblock, clutch and transmission. If your car
fails because of a mis-aligned transmission, you have no reason to blame
It wasn't until I bought my next AWD car that I discovered there was a
smaller bolt on the other side of the block. I destroyed 3 transmissions
in the GSX first. With the damage already done to my crankshaft, I then
lost a shortblock. It's an ounce of prevention that's worth metric tons on
your bank account.
Grade 10 M8x60 bell housing bolt = MD706012. It gets 22-25'lbs of torque.
Owning my mistake permits me to learn from it through con$equence$, and
never repeat it. What good would it have done anyone else for me to learn
this lesson and not share it? That's why I'm providing this video to all
of you. Sharing it can perhaps help someone else avoid this costly
mistake. This is the final chapter for my 7-bolt, and this book is going
back on the shelf.
Here are some valuable resources if you're trying to read bearing damage:
And of course, now that I've covered the complete oil system, transmission
and driveshaft series of videos, you now have all the tools necessary to
ensure your 4g63 lasts a very long time. Whether the casting defect
exists?... or it's all caused by a bolt, or the harmonics, or whatever...
Sure, crankwalk exists and it's horrible. But with the small amount of
movement required for your crankshaft before it contacts the block isn't
far enough to make your clutch drop to the floor when you turn. You'd be
hearing woodpeckers and jackhammers on the crank long before that clutch
pedal would fall to the floor. Some people are going to hate on me for
saying that. That's fine. I believe all of the people who experienced the
clutch pedal issues had fastener problems on their bell housing.
DSMs get a bad reputation for this but we can change that. Crankwalk is
never the cause of your engine failure. Crankwalk is always a symptom of
the real problem. It's your disease that makes you deny it's your fault.
You've got the 'itis. DSM-itis.
Whenever you dig deeper, you'll discover what applied all of those thrust
loads to your crankshaft to begin with, and it's not going to be a casting
defect that moves your crank .101". Mine only went .014", but all of the
same parts failed.
PLEASE tell me in the comments if you find this bolt is missing from your

Cylinder Head 204 - Porting & Polishing
This is a first-generation 1992 1.6L Hyundai Elantra
small-combustion-chamber head. Thats what it is. It's a J1 Elantra
cylinder head. Good luck finding another one like it. (read more)...
In Cylinder Head 106 I talked about the mainstream porting theories as they
are discussed. We looked at a cylinder head that I have thousands of
dollars of professional work performed on, and a bone-stock
second-generation head that I didn't port.
In this video I just might do something you haven't seen done before. For
some, that may be uncomfortable. The port and polish job I perform here is
what I think will work best for my current build. This is not an extreme
killer port job. What will be different here is where port textures are
concerned, I will be following the advice of a reputable source that will
remain un-named. You're free to port yours differently than I do in this
video, and I give you that out, around the 20 minute marker.
The Hyundai is far from being an ultimate-performance build. It's a $400
box of scraps with nothing but time invested. It's perfect for this video.
My finished product WILL be an improvement over what I had. I don't yet
have access to a flow bench. I still have an achievement to un-lock. As
far as you should be concerned with the techniques I employ... without flow
numbers there is no evidence of what this will do, but we will gather lots
of info from dynp sessions and drag strip time slips. If I could test it on
a flow bench, I would.
There are MANY, and when I say many, I mean thousands of flame war
mongering pirates floating around on rough seas with a hair trigger cannon
finger itching to fire if you port a head any differently than what the
herd mentality says to do while porting a cylinder head. I cover the herd
mentality because it has merit. It's been tested. Tried and true. But I
don't follow it to the letter of the law. I'm definitely not here to
de-bunk it. I would port a cylinder head differently for each build based
on how that engine was used. There's an extremely valid reason why
relating to air speed. It's not the texture of a port that maximizes the
effect of fuel atomization, but the velocity of the air running through an
x or y sized valve. The driving factor in this is the piston speed. I'm
not going to give you the technical information, but will refer you to
information about the Lovell factor. There's a better description of this
in the links below, and even a calculator to help you find your engine's
Why the Lovell factor is important:
Lovell gas factor calculator:
Only people who have flow testing equipment know for sure what really works
and have the capability to produce a perfectly-matched port job for the
ultimate performance build. Those guys know the definition of ultimate,
and THEY are floating below the water Aegis-class submarines ready to blow
your comment up if you don't know what you're talking about. They don't
care if you're an armchair mechanic or a herd of pirates. I will say,
they're zoomed in pretty close on me right now, and I'm expecting to take a
few hits. My work will be tested based on Dyno and drag strip performance,
and the results will be posted here. Fortunately, those kinds of videos
are a WHOLE LOT EASIER TO MAKE!!!
Turbo Elantra Bearing Failure Diagnosis
I had time to look at this thing up close. Go through the oil system, and
check out all the bearings. Looks like another good study for my oil
system series because it's the opposite problem that my GSX experienced.
High oil pressure can be remedied a number of ways, but left unchecked can
actually take a toll on your bearings. The way your engine bearings work,
the parts they suspend are supported only by an oil film layer, and flow
needs to be right in order for it to work as an actual bearing. If the oil
supply is insufficient, then it loses the ability to suspend the part
causing it to crash into the bearing surface. If oil flow is too great,
friction is increased, the flow becomes turbulent, and the oil film doesn't
form properly. High oil pressure can float and spin rod bearings, and
that's worst-case scenario.
I had several un-favorable conditions going on inside this engine and that
makes it a little bit difficult to link what my engine experienced to any
one singular thing. I think it's easier to look at it like some sort of
From sub-standard parts for how the engine components would be used, to oil
pressure, to part fatigue, to part history to abuse... this thing's got a
little bit of everything working against it and that's why it's such a
hilarious car. It was given to me with one condition. "See what this
thing will do, and see how long it goes before it breaks." My take on it
is, the parts are still less than ideal, and they've still got life left in
them. It's worth fixing. These parts are worthless as a race motor, and
normally I'd have junked 'em, but it's the Hyundai.
Cylinder Head 105 - Valve Job Basics
Valves not sealing? Valves not bent? This is how you fix that problem.
In this video I outline the basic valve job procedure. Cleaning the
valves, cleaning the seats, cleaning the combustion chamber and lapping the
valves in to make a better seal.
Here I cover the process start-to-finish. It's the same exact process for
pretty much all non-rotary combustion engines. It takes patience and
perseverance to do this job, but anyone can do it. Reference your service
manual for measurements and service limits. Everything else that's not in
your service manual is in this video.
I apologize for not having broken busted crap to work with in this video.
It's more beneficial to all of you when bad fortune falls on me because it
gets well documented, and many people watching these videos are looking for
answers. If you have bent valves, you will discover it quickly once you
chuck one up in the drill. You'll see the face of the valve wobble around
while it spins. You'll see evidence of this damage on the valve seat. If
it's bad, you may see damage on the valve guides in the form of cracks or
missing pieces where the valve guides protrude through the head ports.
Give all that stuff a good visual inspection. ...and if you doubt yourself,
never hesitate to get a second opinion or consult a machine shop. They
will have access to expensive tools that you wont find in your average
New Year's Eve Hyundai Teardown
It goes like this. One of the best friends I've ever had built this car
from junk parts. He said it best, "it was built from literally a box of
scraps". It ran an 13.2 in the quarter mile using no aftermarket
performance parts of any kind. That quarter mile time was limited by
traction. I know this car had more in it, but I never managed to get it to
stick before encountering this.
More on this build...
The proper bolts were not always available, but the builder knows isht from
Shinola. Even though this engine defies all engineering logic from
Mitsubishi, the builder knew what would work and what would not. Budget
was of the most primary of his concerns, and it shows at every turn, and
it's what brought us to the kind of failure we find in this video.
I asked him what bearings he used. He said, "...the least expensive ones I
could find. Picture Aluglides. Now picture generic Aluglides. I paid
half-as-much for those bearings as I would for generic Aluglides.
Bolt too long? Put a nut on it and shorten it. Oil pan too close to the
pickup? Hammer a big dent in it to make clearance for it. Wrong water
pipe? Put a brass hardware store tee in the line to tap a turbo coolant feed. Forget buying ARP's, this is
an all-standard re-used factory fastenere'd no-oil-squirter .030"-overbore
6-bolt with the cut-off balance shaft mod. It's using a small combustion
chamber head off of a 1.6L Mirage with a 2.0L non-turbo block. The plug wires are used. The
radiator hoses were used. Everything but the head gasket came from a junk
car. The FWD turbo gearbox is from my
150,000 mile old Plymouth Laser that donated the block to the Colt. This
is one of the most amusing cars I've ever wrapped my fingers around because
of these kinds of character-building attributes. Nevermind that the
chassis has less than 70,000 miles on it (not bad for a '92), it's just
that it's built without using any new parts. Parts were substituted when
they were not available, and it's ridiculously powerful.
Thank you Jamie. You discovered your answer. I'm happy to help. I'll be
changing some things like the oil pan bolts, bearing quality, some of the
plumbing and fixing a few wiring harness problems, but I'm not changing
anything else if I can avoid it. This car was never intended to have
anything upgraded to deliver raw power, and I'll do my best to keep it that
way, replacing and restoring what failed so that we can keep pushing these
generic non-turbo .030" over pistons to
the limit. Apparently, 24 PSI from a 14b is not enough.
In the meantime, my diagnosis is that excessive oil pressure lead to the
breakdown of the #1 bearing. After all, it's the 1st bearing in-line in
the oil system on the main gallery. It's the most isolated from clutch
harmonics, yet it was the one that spun. The #1 bearing supplies the oil
pump. The teardrop on the head is nearly gone from head resurfacing, and
this is a no-balance-shaft no-oil-squirter block. I think high oil
pressure is why it falls on its face above 6000 rpms. There's a
restriction upstream from the lifters and they deflate at high RPMs, losing
lift. I'll fix it. I've got the parts.
Many of you have seen this one before. I apologize if bringing it back
Domestickilla gave me a crankshaft, and it's a nice one that I want to

Cylinder Head 203 - Valve & Spring Installation
There are 2 critical values in getting your valvetrain geometry correct.
Valve install height and spring install height. On some models of cylinder
heads, getting these values is easier than it is on a 4g63 cylinder head.
On the first Glyptal video, you heard me complain about the complexity of
the casting and how hard it was to reach all the nooks and crannies while
applying that coating. The casting is very complex on a 4g63 head. There
are hydraulic galleries for the lifters elevated above the valvetrain
surface which make accessing each valve bore with precision measurement
tools very difficult. It's because of this that you need to do some math
to get these values correct.
Stuart is going to show you the process for obtaining the stem height and
spring height values on a 4g63 head. Using these numbers you can determine
other work necessary to correct the spring height value to correct seat
pressure, and ensure you have adequate valve travel for your springs to
It looks like rocket surgery, but really it's pretty simple. The ultimate
goal is to get every valve spring in as close proximity to one another as
you can, while doing your best to nail the recommended specification
PROVIDED BY THE VALVE SPRING MANUFACTURER.
Loose valve springs can result in leaky valve seats, valve bounce and
deflection that will drastically shorten the life of the valvetrain. If
valve bounce is severe, it can cause engine-killing interference with the
Tight valve springs can cause excessive valvetrain vibration generated by
the force necessary for the camshafts to push them open. On the narrow
side of the spectrum this can increase friction on the cams which can wipe
lobes and shorten their lifespan, and on the severe end in not only
increases the likelihood of wiping a cam lobe, it can lead to binding valve
springs and crashing the valvetrain.
You have to hit the sweet spot.
Valve springs specifications include several variables that help you
achieve these goals. The manufacturer rates their springs for their
installed pressure and height. They have a compression limit referred to
as valve spring bind which tells you how far you can compress them from
their installed height before the coils begin to bind and the spring stops
The valve springs used in this video are rated at 97lbs @ 1.440" installed,
and .500" lift. This means they should bind at .940", but my cams will
only generate .433" lift, giving me plenty of head room at the top (.067")
to prevent binding if they are installed correctly. One thing we found
which I wasn't expecting is they're a little on the stiff side of spec. We
measured 100lbs at 1.452", so rather than risk setting them up too tight,
that's where we set our tight specification. This decision was made
because if the rated pressure is lower than our actual measurements, this
would in theory decrease the lift specification and increase the
possibility of binding. Our install pressure ended up still higher than
spec with a barely-larger-than-spec spring installed height.
I don't consider this a defect. It is close enough within the margin of
error that it shouldn't cause any problems, and anyone doing this job right
will measure and check all of these specifications to ensure these parts
are what they say they are. That's what you watched us do. I'm confident
that this will work because the 4g63 utilizes a hydraulic self-adjusting
If the stem height is too high, it can be reduced by grinding the ends of
the valve stems to shorten them. This will have no affect on spring
installed height when the parts are assembled, however; it will change the
amount on paper that you'd need to subtract from the stem height in order
to accurately calculate spring installed height. If any of the valves have
been ground to shorten their stem height, all of the valves should be
measured separately with their retainers and keepers assembled, and that
new value subtracted from stem height individually to obtain each spring
installed height. You can't reduce this value any other way short of
replacing the valve seat.
If the valve stem height is too low, you can modify the valve seat or
machine the valve spring perches (seat or retainer) to increase the size of
the spring installed height. Another method would be to cut the valve seat
deeper to recess the valve.
In my video, we show this whole process on a brand new set of Supertech
valves. All of them are identical, and all of the retainers are new and
identical. Because of this (and yes we checked it), and because no valves
required any grinding, we only needed to use one value in our math for all
Hopefully this video clears up the process and covers the options available
for making changes if they're necessary. If you land within 3% of spec,
you've done your diligence in achieving correct valvetrain geometry.
Calculate Your Compression Ratio
This is everything you need to do to calculate your compression ratio. No
foolin'. Every equation and process demonstrated. Find all your
variables. Know your exact compression ratio in every cylinder. This is
how you do it.
Just because your service manual says your car is 7.8:1 or 8.5:1
compression doesn't mean that it is. Whenever there are casting
irregularities, variations in piston height, parts that have been machined,
non-OE parts, or changes to your head gasket selection, your compression
ratio WILL change. It's highly probable that you're only CLOSE to spec if
you've never touched your engine at all since it was "born", and that it
doesn't MATCH spec. Even if it did, how would you know? This.
V1 Swept Volume
V2 Deck Volume
V3 Piston-to-deck clearance
V4 Piston dish cc's
V5 Head combustion chamber cc's
The ratio math:
V1+V2+V3+V4+V5 = volume of combustion chamber at BDC
V2+V3+V4+V5 = volume of combustion chamber at TDC
The ratio is...
(V1+V2+V3+V4+V5) ÷ (V2+V3+V4+V5) : (V2+V3+V4+V5) ÷ (V2+V3+V4+V5)
BDC ÷ TDC : TDC ÷ TDC
First you fill in the variables, then you calculate volumes, then you add
the volumes, then you reduce the ratio (fraction). It's that easy.
Here are your magic numbers:
0.7854 = Pi quartered to the ten thousandth
16.387 = number of cc's in a cubic inch.
If you divide any number in cc's by 16.387 it gives you inches. If you
multiply any number in cubic inches by 16.387 it gives you cc's.
Quartering pi lets you use the calculation:
BORE x BORE x STROKE x .7854 = volume of a cylinder
π x (BORE ÷ 2) x (BORE ÷ 2) x STROKE = volume of a cylinder
Either way is right. You get the same result if you calculate pi to the
ten thousandth. While I apologize for all the math, no I don't. I'm
really not sorry. You actually clicked here for it whether you realize it
or not. This is ALL the math, the tests, and the whole process to
calculate your cylinder volumes and compression individually even if you
don't know any of your variables yet. All of my numbers are present for
those who want to calculate out the last 3 cylinders out of curiosity just
to see how it affects cylinder volumes and compression ratios from one
cylinder to the next. Why would I do that for you? Why would I deprive
you of that practice?
Just assume that all 4 of my combustion chambers are 41.75 ml if you do
Clicking like share and subscribe helps a channel grow. It also motivates
me. Don't sweat the camera. It's enough to know that so many of you care
about what I'm doing here. From the bottom of my atmospheric dump, I thank
you all! This gift horse's teeth are all over the place, but he sometimes
poops gold nuggets.
PS: Use ATF for your piston dish volume tests, not alcohol. Of course
it's better just to use the spec sheet included with your pistons... but
not everyone gets that luxury. Water is just fine for head combustion
chamber tests. Dry and re-oil all parts that water touches.
Porting an eBay 20g turbocharger
The price of this turbo will make it a
popular purchase, so I figured I'd air out some tech about ways to improve
it. This thing is not for everybody. I wouldn't feel comfortable bolting
it on my car the way it comes out of the box. I could complain about its
flaws except that so far absolutely none of them have been a deal-breaker
for me. To me it's like an empty canvas. I promise to eat those words if
it happens, and share my poop. Usually I can easily correct these flaws
myself and so can you.
If this thing turns out to perform well with what I do to it... It could
easily be a cheap, quick ticket to an 11-second car. Something you could
do with a free running 1g, a hacksaw, and about $500 worth of fuel
upgrades. Yeah, that would be ridiculous, and I'm bolting it onto a
well-modified car... But that being possible speaks volumes for what a DSM
can really do.
This is no big deal to me. I'd rather guinea pig my car for you in HD so
you guys can decide whether or not you'd spend your money on this. Really
it's an experiment because this isn't my daily-driver, and it contributes
to building a better Colt.
Tools I used involve:
Milwaukee model ???? 1/4" straight-shaft electric DIY grinder
Cone and ball-shaped double-cut burs
180 grit high-speed flap wheel
Dremel with a flex-shaft and a tiny 320-grit flap wheel
a zip tie
10mm combination wrench
tiny flat-blade screwdriver (00) for the e-clip on the wastegate
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.

How to Rebuild a Turbo - Part 1 of 2
Rebuilding a td05h 16g turbo. This
process can be applied to many journal bearing turbochargers. :) It definitely comes in handy to
know how to do this when you are in this type of hobby.
4/25/12: Small explanation on the balancing of the rotating assembly since
I get so many comments regarding it. This particular turbocharger, td05h, has its rotating assembly
components balanced separately. This means each individual part (compressor
wheel, turbine wheel/shaft) gets balanced separately. This allows for easy
interchangeability of parts in case they need replacing. This is why I am
able to install a td05 20g wheel on this turbo without having to balance the entire
rotating assembly. THIS IS NOT THE CASE FOR ALL turboS OUT THERE. You need to research whether
your specific turbo (if it's not td05h)
was balanced as an assembly or "component balanced" like I explained above.
I hope this information helps. Good luck in your projects. Stay Boostin'
