Okay, yesterday I pulled the crossover pipe. Holy cow, it was like the La Brea tar pits in there. I couldn't believe it. Black, soupy, wet oil deposits all the way through and into the intake manifold. That must be my problem. The turbo. So I pulled the rubber intake hose off and in the turbo air intake side, there was about what would amount to 1/4 teaspoon of oil sitting in the aluminum allow intake sleave.

I would have not been surprised with a little bit of oil. But this was thick caked. I think the turbo is sucking massive amounts of oil or the valve cover vent tube that goes to the rubber air intake duct is pulling oil.... Which I don't think it is. There was some oil in the rubber duct but not a massive amount. I would expect some there too.

Anyone have any ideas?

Has anyone rebuilt a turbo on a 603.971? Is it difficult? Can you get parts? If so, where from?

Any and all replies greatly appreciated. This is new territory for me!
