Default Re: LT5 Assembly Project

I tried putting the outside bolts on, as suspected, it made no difference.

I then swapped bearings, no difference....I also checked the surface of upper and lower block, smooth and no issues.


I had the crank checked, fluxed and polished, no issues

This is weird

This is probably a silly question but did you mark the caps before dis-assembly and then place them exactly where they were before?

I'm not familiar with the recoated bearings, could they be too thick. Plastigage, or micing it as A26 mentions might verify where the problem is. Sounds like it would off to the machine shop, if all that checks out. But since it's the same crank and block, seems strange it won't fit all of sudden.

Dropped off the block bearings and crank at the machine shop, will let you know what they find.

Still waiting; race season means daily driver stuff goes to the back of the line at the shop

Lee did you have all the bolts run up ( main and girdle ) ?

I know when I did mine it was kind of locked. I had to work the crank front to rear (thrust). Then worked it normal rotation. After that it moves freely, with a high break away feel. The block definitely moves around. The liner are about .003 -.004 out,tapper without head or tq plate.
