[6pack] Fw: compression

[DLylis at aol.com]

Al,
Wet test.  Take out the spark plug and squirt oil into the  cylinder.  Do the 
compression test.  If the results change then the  rings are contributing to 
the compression readings.  If there is no change  then the issue may be with 
valves.  Understand, of course, that it may  be both to some degree.  
 
Leak down test.  Introduce compressed air into the cylinder and put an  ear 
to 1. carbs; intake valve leak 2.  exhaust; exhaust valve leak  3.  sump; 
piston rings.
 
My guess is that you have excess positive crankcase pressure because of the  
oil leak at the sump gasket that doesn't stop.  IMHO
