low compression.. all cylinders? - reply

[John Hertog <crossram@xxxx>]

Mike,

I agree with Don. ; the only way to know for sure where the compression is
going (leaking) is to put a cylinder at TDC, then put compressed air in that
cylinder and listen to hear where it's escaping. Out the tailpipe = rings
froze; out the intake or exhaust = bad or frozen valves. Repeat procedure
for each cylinder and you will know exactly what you're up against ! If
coming out intake or exhaust, sometimes rapping the affected valve with a
BFH (Big F... Hammer) will unstick it.

Look at it this way - things could be a lot worse, you could be here in the
Northeast freezing your butt off, instead of in Phoenix working in your
driveway in a t-shirt !
