Jay, are you sure that leak down tester is working? I can't imagine how any
cylinder, let alone all six, can be that high.

I agree. I never saw one over about 76 in 30 years of measurements on
a new O-320E2D.

We've seen 79 here a few times. Typically mid-70s on airplanes that
are flown every day. O-320E2Ds.
