The head has not been removed from the engine since the issue occurred. We have been trying to diagnose the issue before disassembling the valve train and the head. I feel I have a conundrum on my hands. If I don’t find the offending issue then I don’t know what to fix.
Air pressure test of 21 lbs overnight showed no leakage and wet pressure test of 32lbs showed no leakage.
I am planning to replace the copper line that feeds oil to the valve train and I might have to pull the head, magniflux again and try that. However that is just changing stuff and spending money because nothing seems cracked with either or we should have pressure leakage on the coolant tests
