Squirt some motor oil in number 6, turn it over a few times, and repeat
the test. If the compression on No. 6 goes up, you have a problem with
the rings or cylinder wall.

Subject: [oletrucks] Engine Blow-by
The 235 engine in my truck runs as smooth as silk, but seems to
have an
excessive amount of blow-by coming out of the draft tube (or
from the valve
cover cap if it is removed). I did a dry compression test which
revealed
that cylinders #1 to #5 were right around 130 pounds, but #6 was
105. Are
these two problems likely related? What are the possible
causes?
Thanks,
Mike Auser
