[aaron87turbogn]

Yesterday I did a leak down test and seems as if my calves are good and my piston and rings are good but when I put pressure in cylinder in the middle on driver side air was pushing out the 2nd push rod hole in in the 1st cylinder but cylinder 1 had 150 psi compression and cylinder have problems with is 30 psi has brand new head gasket

It is not unusual for newer members asking for help, but with very little info and background on an issue it is hard to give an intelligent response instead of a wild-ass guess?

Did you have an issue that was recently repaired, or 30 psi suddenly appeared?

Either way, the head needs to come off to be repaired, or the head gasket replaced.

Could also be a crack in the cylinder, but that is only a remote possibility.
