I am in the process of a pre buy inspection, the piper arrow has about 430 hours on factory new cylinders but upon checking the compression today after a 1 hour flight they were all over the place. We bored the cylinder and they all had visible pitting, valves looked good. I would think the pitting would be minimal, A&P said it wasn’t really bad, one cylinder was 42 the first check and 44 the second check.

I don’t want to buy a problem engine, just curious of your thought.
