Check out this 4g63 rebuild

[Pimpin Dsmstyle]

I think it's something more along the lines of he worked with someone that was a freak about building motors. Granted, I think that's part of his job now, but I doubt he's built 100's of motors or anywhere close.

Alot of the points he showed was common sense things. That and he was rebuilding a 7 bolt, no point - waste of time. With those 2 problems, that was most of his errors on the assembly.
