Ok, I drove the car 39 miles home from work tonight with no issues. Granted I took it easy and never went over 2500 or so RPM. Took it apart and here is what I found.

1. The valve cover gasket has a small tear in it at the corner contributing to the leak, and the drivers side fron bolt was barely finger tight (must have loosened due to vibration).

2. The U-tube from the turbo to the air cleaner had about a tablespoon or so worth of oil pooled in the low spots, and of course had a fine sheen of oil over all of the inside. The turbo outlet itself had a few drops but nothing major, and the air cleaner had maybe a thimble full of oil in it. The last time I had the tube off was about 20K or so ago so the oil may have built up over that time.

My plan is to put it all together and run it for a couple of days and then pull the U-tube off again and see what I have. If it is full of oil or it unintentionally accelerates again, I'll see about getting the turbo rebuilt.

Based I what I have reported, do you think this is a sound plan, and do you think the turbo may be the culprit?
