[TPR] Asa's Engine rebuild update

Sat Jul 21 08:54:41 PDT 2012

Asa, I've never done that (shimming), so not sure.  I've always checked clearance with oil (operating conditions) on all bearing surfaces (not dry) so not sure if that makes any difference.  I also use oil or grease to hold the plastigauge where I wanted it.

Hopefully you'll hear from Russ or some other knowledgeable engine guy.

Anyone?
JB, any opinion on the use of shim stock to tighten up the tolerance on 
the main bearings?
