Re: What would allow good leakdown, but bad compression?
Posted to Technical Discussion Forum on 4/6/2016 2 Replies

One option not suggested yet:

Water ingestion -> hydrolock -> bent connecting rod -> Extra volume at TDC therefore lower compression test readings.

Pull a couple plugs and compare "depth" guage readings to cylinder top at TDC. Login to read more.
