the only way the oil can get there is down the push rod or from the pan being forced up the drain hole by G forces in the turns. see if you can put a baffle in the pan to keep the oil from getting into the drain back hole in the turns

There used to be a company named seals it.
They sold a boot type seal that kept the fuel pump from being overwhelmed with oil and pissing out the vent holes.
Not sure if they are still available but we used them for years till 2000 and something when we went to injection.

May be worth a search to see.Buy 2 if you can as they don't last forever but a couple seasons were what we got out of them.

We had to get the grinder out and open it up. Next time you have the engine torn down you may want to check that. That could definitely prevent proper oil drainback.
