Im doing a basic budget rebuild on my 6 bolt motor. .020 oversize on oe style pistons and stock rods.
the crank will be getting a micropolish and new bearings.
I have never rebuilt a 4g63 before and my colt is really my first foray into turbo mitsu stuff. Needless to say im hooked. With this rebuild in mind i have been reading till my eyes bleed all about engine rebuilding. I came across information regarding the press fit balls on the crank that mitsubishi used to seal off the access holes for cross drilling the oil galleries.
one guy was saying how important it is to remove them and clean the galleries real well. Then tap and install set screws to seal off the hole. Now i cant argue with cleanliness but removing those balls and rethreading in set screws sounds like a lot of work
To the guys who have been doing this a while and have rebuilt many motors whats your opinion on that?
As always much appreciation to your prior experience
