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
clean up and use again. You'll be seeing a lot of it and because of this,
this video deserves to be here. I fixed what I broke, and this was my

Blueprint 104 - The Crankshaft
It's important to know what you've got even before dealing with the
machinist. If you want to inspect a crankshaft, this is how you do it. I
detail the process of removing the crank and what to measure. All
specifications in this video are illustrated with a 6-bolt 4g63 turbo block, but are all actually the same for
7-bolt engines with the exception of the rod widths.
Block Preparation Part 1
Preparation for powder coating and Glyptal application. Audio track is an
original performance by Rojo Del Chocolate.
My block is being powder coated rather than painted. It's just something I
do. The GSX had it on the last block so it's getting it again.
Since the tools are so similar and the mess is the same, I'm going ahead
and preparing it for the Glyptal application as well. These 2 coatings
will require being baked separately. The powder coating is baked on at a
hotter temperature than the Glyptal, so it's going first.
The surface preparation instructions for Glyptal is as follows:
Surface to be painted should be dry and free from dirt, wax, grease, rust
and oil. Remove all grease and oil by washing surface with mineral
spirits. Wipe or scrape off all loose dirt, rust or scale.
The last sentence is what's covered in this video. The 2nd sentence
happens next (although it's already degreased), and I'll get it back from
powder coat with it in the state described in sentence #1 completed. If
following these instructions to the letter of the law.
Second and third opinions in... the main journal is fine.
You'll notice that I didn't coat the main caps, or "suitcase handles". I'm
not going to. You bang around on these installing and removing them, and I
don't want to risk chipping them once they're coated. They're below the
windage area, and there will also be an un-coated main bearing girdle down
This video covered 25 hours of actual work. Yes, I kept changing into the
same filthy clothes every shoot because I wanted it to look consistent.
You have to take your time doing this kind of work, and be VERY VERY
CAREFUL! If for some reason you're crazy enough to attempt what I do in
this video, you do so at your own risk. This is an elective treatment that
I've never done, but I am by no means the first person to do it. I'm
learning about it just like the rest of you.
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.

How To: Pressing Press-Fit Wrist Pins At Home
This video describes an easy method of pressing wrist pins into pistons.
This method is better than using a hydraulic press because it doesn't put
stress on any of the components.
Of course, luck would have it that the pin I was pressing for this
demonstration stopped short because I didn't have everything lined up
perfectly, so it snagged and the rod cooled before I got it the whole way
through (like I said, you have to work QUICKLY! :) No big deal though.
The particular piston/rod set I was working on at the time was a set of Evo
9 pistons and 1G 4G63 DSM rods to be put into the block that is seen behind
