My comment about the venting is not wrong--the problem is where the vent is located--in an application like yours and the ones you mentioned that use a lot of aero devices--the pressure balance over/around the vehicle will pull the oil out---thats why your stated about 1/2 BELOW the baffles works---

EVEN IN AN FE engine you can pull a vacume in the pan---the pan doesn't know what kind of engine its on--if you can't pull a vacume with a decent modern pump, you haven't got your engine sealed up

The last engine I have numbers on pulled over 20 HG all the way to 9500 rpm and was making 1370 HP. It was a pump will the lobed gears--the same type package with the older geared pumps pulled steadily over 10 HG at about the same rpm/hp numbers----

If you can't pull the vacume instead of trying another pump, fix the engine.


It has happened----yep _ _ it happens!!!
