I was second guessing my choice of oil at the time, but the store didn’t have any rotella in stock. Although I think heavier oil will help, I have a gnawing feeling that there is more going on. If the freeze plug really is leaking I’ll pull the engine and check bearing wear, etc. I’m going to get it up on stands tonight and go looking for the leak.

Late update-leak is definitely coming from behind the flywheel. Motor is coming out. Warmed it up and had 25psi at cold idle again, dropping quickly as the coolant temp came up.
