So, your engine was a fresh rebuild? Not just a valve job, or ring/valve job?
Given the small amount of looseness (1/16 turn) that you found, and only four hours of operation, I’m guessing you left something out, or did something wrong, during the rebuild.
You could just try a fresh head gasket, making sure you get it right. If you get the same results, you’ll want to pull the engine and go looking for the problem.
It’s likely NOT the drainback holes. That’s mostly an issue of external oil leaks. You’ve probably got a pressurized transfer somewhere. That could be head gasket, cylinder o-rings, head gasket o-rings, cracked head (or block).
Remember, your engine makes more oil pressure than water pressure. Oil in the water only is one thing. Two-way transfer changes the likely sources.
