You ask more questions than anyone ive seen..

Generally with ACL ive gotton .0014-.002

i like anything between .0015-.002 have had great luck with that clearance... the Factory clearance is a little tighter than that..

Im just overly paranoid and like to double and triple confirm stuff sometimes. Just had a lot of bad luck with my car.

Appreciate the replies though thank you

What do you think of .003 clearance for the main bearings? That was a common number I came up with when searching and mine came out to right about that on each one

So I re-downloaded the FSM and found that the copy that I was using was missing a lot of pages

I found this page which shows the clearances to be .020 to .040


ImageI know this is Factory not ACL butt where did you look up the specs for those numbers
