<VV> Fix or rebuild 65 110hp engine?

[J R Read]

I guess that I'd like to know what was included in the 1980 rebuild - before 
even attempting a guess at the problem.  For example - new pistons?  What 
kind?  What rings?  Heads through the machine shop?  What done there?

0 psi is telling me a holed piston or stuck (open) valve - possibly a loose 
seat holding it open.

Anyway - removal of the right side head will likely answer your questions. 
It is possible that it is nothing more than a broken ring and (if so) how 
did the CRs on 3 and 5 look.  Head is off, I'd do the whole bank with fresh 
rings so long as cylinders are in spec.

Ramifications?  A much better running engine....   the goal anyway.

Later, JR
