    Not to promote another source but go to Rennlist. com search the turbo forums for Kevin from Ultimatemotorwerks. He goes into great detail, including pictures, why oil in the I/c tubes is a sign of failed turbo seals or worse. Don't know if he's still around but he knows his stuff, and his work is/was aerospace quality.

    My I/c hoses have zero oil in them. Oil in the air flow is not a design feature. It will cause all sorts of secondary issues as it gets ingested and burned in the combustion process. Turbo-side (turbo to intercooler) is where to look for oil contamination. You may be better off with sand in the turbo's than coked oil, at least the oil filter will catch it- coking is forever until disassembly. BD

    sorry brain freeze

    Your turbo's bearings are on the way, if not already, shot. They're looking at a turbo rebuild or replacement. The oil gets coked up in the bearings from the latent heat after engine shut down, and just grinds away at the tight clearances. The pressure created under boost then blows the oil across the bearing 'seal' into the air passages. Did the former caretaker do a cool down before shut down? I let my turbo cars idle about 2 minutes before I shut down just to let the oil cool a little, since oil flow is the only thing that cools the turbo's. I also switched to Delvac 1 5W-40 which although a heavy duty diesel oil, it's rated SL for gas cars and is designed to resist the high temperature coking in the turbos of diesels. Not entirely kosher as far as Porsche's recommended oils goes, but what do they know anyway? ;)

    No offense Golden, but how in the heck do you prime the oil filter in a 996tt? The canister goes in basically upside down and there's a drain valve built into the housing to facilitate removal w/o spilling oil all over the place. BD

    Bad plug or coil pack? If you are changing plugs, go with Bosch FR6 instead of Beru. Did somebody try to adjust the turbo waste gates? If you put too much boost the ecu will try to protect itself. Bad diverter valves (mechanical) usually honk like a goose (no joke) when they go bad. BD

    Good luck, BD

    Front radiators full of road debris, coolant reservoir leaks, grease stripes on front door windows, minor oil leaks, MAF issues with oiled air filters, automatic spoiler issues, smoking on start up. Sounds worse than it is. Most everything is minor unless it's been flogged. BD
