Has anybody taken compression and / or leakdown tests on a freshly
prepared engine and compared them with the engine condition after a
season of racing?
I try to watch them close. There are many variables re service life but
usually the valves will leak before the rings will.
Average fresh engine after run-in is usually 2-3%, some less. Once they get
into 2 digit numbers I get concerned (race engine). Street engines will leak
30% or more & still run well...
