That means you engine is good and strong. I wouldn't worry about the 150
number, I would worry about large variances among them. The tester he used
could be out of calibration enought to read a few psi higher than it should.
The relative difference among adjacent cylinders is more important than the
actual numbers you get.

Me too. I wouldn't give it a second thought. I would spend the time it takes
to pour water or ATF down the intake to get to my favorite wheeling spot.

Hi Bill,
You have a really good battery and starter. ;-) Anyway you
definitely don't need rings, just replace the stem seals and your puff
of smoke should be gone.

March and was worried about the condition of the engine.

Thanks all,
