Loosing my mind

Doesn't sound right to have two different readings. Sounds like maybe a valve was hanging open during the second test?
I know your very mechanically inclined and not trying to offend you.
Compresses air into the system is only one obvious sign of a blown HG between the CYL and a water jacket. It could still be blown elsewhere. Maybe start it and remove the oil cap. See if your getting excessive pressure into the crank case? I know it's not typical to have loss of compression and oil in the hole at the same time but if it was a typical problem I don't think you'd be on here for input from others.
