of course i am being over-dramatic. the point that i am trying to make is why do anything if we are just going to wait until it fails? do you test oil pressure differentials on a recip? if it is close to the trip point but not tripping would you not try to stop it from catastrophically failing? have i replaced a compressor based on an oil sample result? not yet. but I have diagnosed problems and repaired them before failure based on oil sample tests...high copper content was a semi-recent issue. I haven't changed out a functioning compressor due to megger results, but I have investigated and remedied issues on compressors in the past.

Someday, I hope to be just as brave as Harry Stamper.
