Wayne - If you could just clarify a bit. If the compression numbers are good, then how can leakdown numbers be bad? Are we really measuring two different things, or is the leakdown test just a more sophisticated way of identifying why the engine is unable to hold (or build) pressure? If an engine is leaking badly, then wouldn't it be unable to build pressure to give good compression numbers?
