unintended acceleration! Kinda urgent

[psaboic]

Need some help.

On the way to work today, about 15 or so minutes into the drive, I noticed the car suddenly being VERY sensitive to the accelerator pedal. If I was going above 50 mph (about 2500 RPM according to the tach) I could feel it trying to accelerate on its own. Letting off the pedal and lightly applying the brakes brought it under 50 and it acted normal.

A few minutes later it started doing it again, but a little stronger. I slowed down to a stop and put it in neutral and it instantly revved up to about 5 grand. I shut it right off with the key and it shut off fine, but there was a cloud of black smoke in the air.

I waited about 30 seconds and started it up and idled fine so I drove away. All was fine until about 10 miles down the road when it started doing it again, but this time it was lightly pinging and I saw blue smoke out the rear window. I applied the brakes, brought it under 50 again and it was fine the remaining 10 miles of my drive.

I got to work, and popped the hood. the whole front side of the engine, the firewall, and the IP and linkage are covered in motor oil, as well as the injectors and lines. I just replaced my valve cover gasket and I think that is the cause of all the oil as it is simply not sealing well at all. But could that cause it to try to runaway?

I'll check the oil level in about 4 hours to see where it is at, but could a leaking gasket and oil spray cause my sudden acceleration issue? The car is a 83 300D turbo, and since the shutoff valve and brakes work fine, I think my vacuum pump is ok.

Gotta drive it home today so any ideas are appreciated.
