[oletrucks] Engine Blow-by

["Mike Auser" <auserm@hotmail.com>]

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,
