Volks,

An unsettling lack o'compression in cylinder #3 has me investigating the
procedure for adjusting valves. (BTW - the PO had the heads done some miles
ago).

A leakage test shows no leakage in cylinder # 3, but it intermittently reads
low on compression

Reading the Bentley manual, there doesn't appear to be any specs on valve
clearance (adjusting valves and measuring gap w/ feeler gauge, e.g)  All I
can find is a description in the section on assembling heads where it says
something like "at TDC, back all adjusting screws so they're flush w/ Rocker
arm, then turn them til they're tight up against (pushrod?) then back them
up (or sock them down) some fixed # of turns".

Any advice?  It seems like there should be some specs that I need to adjust
the valves to...
