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 a price.
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.
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.
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.
Cylinder Head Re-Polish
UPDATE: INgrooves and Believe Digital have filed fraudulent strikes
against my YouTube Channel for this video. They do not respond to
disputes. If my disputes expire without first being dismissed by these
labels, I will never remove this text because others deserve to know about
the copyright abuse of the recording industry. Record labels file claims
on YouTube to content they don't own because they want to steal other
people's creative property, install their own advertising, and profit from
works they had nothing to do with creating whatsoever. It's their new
business model. They are doing to the public what they've been accusing
the public of for decades.
They and the artists they represent can not legally stake any claim against
my audio content as it was created 100% with loops owned and provided
ROYALTY-FREE by Apple Computer, Inc. These USAGE RIGHTS come with the
PURCHASE of Logic Pro Studio. APPLE INC. RESERVES OWNERSHIP RIGHTS of this
royalty-free content used to produce my audio track, not the artists that
these entities have fraudulently submitted for waveform scanning to the
Content ID system. The license agreement can be found here:

the equipment used to produce it, and possess the receipt, packaging and

4 other un-named labels have also filed claims on this one video. 2 were
dismissed within hours of submitting the dispute, 2 required more than 2
weeks of digging through public web forums until someone provided me their
private email addresses and it still required several emails. The two
remaining have completely ignored their responsibility to respond to the
dispute process, which takes 30 days to expire. One of them will be
immortalized here permanently as of October 10th, 2013.
YouTube is not taking adequate measures to ensure the record labels own the
materials they submit for waveform scanning. YouTube does not provide
contact information to YouTube partners for any of these entities who file
fraudulent content ID claims and then ignore disputes. YouTube does not
remove the works submitted by record labels that include public domain,
royalty free, fair use or licensed samples. It appears they don't do any
screening of the works submitted by the labels. YouTube needs to fix these
issues for the sake of your quality entertainment because uploaders are
suffering from the lack of these features, and this kind of e-bullying will
stop channels from producing and uploading quality original content for you
to watch. Time I spend disputing claims and ownership rights is time I'm
not wrenching, filming and editing. The recording industry has devolved
into a waste of everyone's time. Their usefulness in modern media
distribution has driven them to these desperate measures to remain relevant
and profitable. Now they just resort to harassing other self-made artists
that they don't represent over content they don't own.
Hey, you know this is just one of those extraneous things I have to do that
takes time. This car won trophies for this, and it has a reputation to
When we're putting this thing back together, there's a certain order I have
to do things in. Polishing comes before the final cleaning and parts
installation. After that, it never ends.
This is purely cosmetic. I created the soundtrack using Logic Pro.
Because I can. It's mine.
Hyundai Assembly 1 - Blueprint Everything
HOLD ON TIGHT! HERE WE GO!
We begin the blueprint and assembly on my 1992 Hyundai Elantra's
bastardized 4g63. The parts used in this are from a mash of different
brands and models outside of the typical 2.0L 4g63, but the specs and
standards I am following for its assembly are for the 2.0L DOHC.
If you want to follow along in your service manual to verify what I've done
here in this video, the processes we cover here detail pages 11C-95 through
11C-105 of the 1g Overhaul manual. I would prefer you not rip them from
the binding and throw them away, relying only on this video for
instruction... but rather use this video as a motivational guide, and as a
demonstration of the techniques involved in those sections.
You gotta do the cooking by the book.
I never had any intention of making instructional videos on this particular
car, but after it blew up I slowly realized it's actually a better case
study for how a 4g63 ticks than anything else in my driveway. There are
several reasons for this. One being that it's a mix of parts that
shouldn't be bolted together, and the other is that many of you watching my
videos aren't trying to build a 600hp engine out of aftermarket parts.
You're trying to put back together what used to be your daily driver. This
car covers those bases. Don't think for a second I won't go through this
same trouble and level of detail for the GSX. I will. When I do, having
this information in this video will give you a better understanding on how
and why I do things the way I do when I get there.
This was the shortest I could condense this video. I've never uploaded a
video this long, and I hope I never have to do it again. It took a month
to create on cutting-edge equipment, 16 hours to export, and 9 hours for
YouTube to process. My script for the voiceover is 6 times longer than the
whole script for the movie Pootie Tang. 6 times. Longer. Than a
