If I had to have oil at the drivers side I'd pull it off the gauge port. Much cleaner and the lie of oil velocity would die.
Read post one. Robert thinks its a velocity issue. It's not. Its a leak issue. AT 8500 plus a bit I was using a machined down pump. I think I still have the rotor and scroll out there and maybe the pump body. I think it was at 85% of a standard pump. And it was on the big side.
Stop the leaks. Control the oil to the rockers. Fix the inlet side of the pump. That's good enough for 99.9999% of the guys posting here.
