4G63 back from the ashes---First half of engine rebuild
After over a YEAR of promises that I'd get this vid done, I went halfway and got the engine pull and most of the shortblock work edited and documented. Here for your viewing deliciousness is PART 1! (link to torque specs for the engine here: http://bit.ly/17KDEED)
CRANKWALKED? 7-bolt teardown 1080HD
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.
6-bolt 4g63 shortblock rebuild parts
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
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
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.
My Galant and the process of rebuilding its engine
6-bolt 4g63 Kiggly Main Girdle Install
Ballos Precision Machine was nice enough to let me into their operations
and film the installation of my 6-bolt Kiggly Main Girdle. They let me do
this as a gift to all of you.
THIS IS NOT THE FINAL INSTALLATION.
Though all the parts were cleaned prior to pickup, they will be extensively
cleaned again, and the fasteners installed finger-tight with red Loctite
exactly 15mm above the surface of the main girdle and torqued in the proper
My main caps were level and straight, the crank bore was straight to begin
with, and had never been line bored following the original assembly at the
6 bolt 4g63 in 2g Eclipse GSX cylinder head removed in under 10 mins
Removing the head of a 4G63 in 10x speed.
The project got delayed a few months. After finishing it and cranking it
over, Interference in the cylinder was discovered. Shamefully, I admit my
mistakes were: 1) Not putting the spark plugs in immediately after
installing the head. 2) The bad habit of using my Valve Cover as a parts
tray and 3) Putting off the project too long, so I didn't recognize a
missing bolt from a custom fabrication.
The head needed new valve seats, valves and some welding. Wiseco and the
machinist both thought I'd be OK running the piston after smoothing out hot
spots, but I ordered a new piston not wanting to risk the deep gouge in it
with the high Boost I plan to run.
Peace of mind is priceless.
The danger in being over confident is sometimes you skip triple checking
stuff. I've built that engine at least 5 times and got careless.

4g64 DOHC Build-up
Here's a short video of my 4g64 with 4g63 head Build-up.
I still need to tune the motor a little as you can see or hear in the
video, the motor sounds a little rich specially after 7000 rpms. Dyno video coming soon... Hope
you liked it..
Piston Wiggle in my DSM
So im going to guess that whoever put this engine together had no idea what
they were doing. All four pistons have a wiggle to them. You can almost
tell in the videos that the gap is too big. Almost as if they were the
wrong bore or something. Oh well, out with the old and in with a fresh 6
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.
