968s sucking oil into engine somehow???

[Frank A]

I have a 2000 Boxster S that smoked just like yours when I bought it.
If I took a spirited left hand turn the oil smoke was amazing.
I changes the AOS, cleaned the intakes, and still clouds of oil.
While I was changing my IMSB I noticed my pass side oil pump was installed wrong ( Keyed to 2-6 not 1-3) so it was not evacuating the head of oil.
My motor has over 120,000 miles so I'm sure the valve guides are hard and leak, but from the time I keyed the pump proper no more clouds of smoke.

Good luck

Yes, a backward installed scavenge pump will certainly cause this.
