Scroll down to pic 4. That little plug would be easy to overlook. Since it works like a freeze plug there's always an off chance that it's in crooked or a hair under size. The only issue is that you'd have to pull the front cover to check.
If you do open it up I'd also be looking at pickup to pan clearance, o-ring pinched, pressure relief valve sticking, plus whatever else I could see while I was there.

And this to keep the oil pick up tube mounted flush to the pump.

1200-1300hp probably have large bearing clearances. That can lower the pressure if you do run heavier oil and the oil pump spring change.
To check pan to pick up clearance I like to a piece of tape over the pick up screen and put a piece of clay on it, then set the pan and gasket and snug a couple bolts, then remove and measure the thickness of the clay.
