It looks to be coming from the air intake pipe that enters the turbo. The reason for this is, even with the standard petroleum based oil, the scavenger side of the oil pump is marginal for the motor. I will also realign my oil pump (although I did that when I did my 95 conversion and put cam chain tensioners in) and replace breather umbrellas in my heads. It has been leaking for some time now and i have followed where it goes. Leakage then drips down where it appears to be coming from the breather pipe. Noticed over the last two weeks my cam cover is leaking oil, I guess the gasket needs replacing.
