oil cloud when running hard

[Jake Raby]

Is the pic of the scavenge pump taken on bank 1 or bank 2 of the engine? Its not totally clear.
Have you taken the scavenge pump apart? It is symmetrical and the body can be assembled out of phase and still fit, but have this symptom.

Before pulling engines wouldn't it be prudent to test the pump output on the bench (or even swapping / comparing pumps with the other cylinder) and if OK, pressurize the pump discharge port in the head to make sure that there is no blockage downstream of the pump.
Even oil from a hand operated oil can should be able to create enough pressure to see if the oil discharges into the sump.....

Thanks Jake and Steve for responding, This is on the passenger side head on a Boxster. I have taken the pump apart twice and it is phased correctly on the plates. When I hand turn the pump clock wise when looking at the pump shaft it pumps out of the correct port in a bath of oil. The valve cover 'oil pickup port' is clear. I removed the oil pan again and blew air into the presure port and air freely comes out of the Drivers side swirl pot.
