One thing I did with mine, when I had oil puddle issues out my Zork with a rebuilt turbo, was to install a restrictor plate in my oil supply to the turbo. This doesn't totally solve your problem, because if it is due to poor rebuilds, it really should not need it. But I made a small plate to fit under the banjo bolt, and installed a small/light spring on top of the check ball. Chris at TK offers the same spring mod and I think it is derived from the 964T. Above the spring I made a small plate (maybe it was from a washer - was a while ago). I drilled a series of small holes (maybe about 1/32") around the circumference in a line just inside the bore diameter of the banjo bolt. When I totalled the surface area of my holes up I was at about 1/2 the diameter of the previous oil line at that point. That is still in place several years later.
Regards
Alan
