Hi, I am getting ready to go on a long trip and I would appreciate any
help/advice on this issue.  I was changing my oil today and managed to
get a poor seal on the new filter (totally my fault - just stupidity)
and the oil that sprayed out (yes there was quite a bit) covered the
driver's side of the engine compartment.

Well, I got that fixed and cleaned up - filter is fine, all new oil,
good pressure, runs well...but now my car won't shut off (without
hitting the red stop switch).  I cleaned the engine (as much as
possible) and don't know if a sensor got damaged or oil covered, or
something that I can't see - and I really don't know where to start
looking.

As I mentioned, I am going on a long trip this week (which is why I was
changing oil, filters, etc) and would really like to fix this.

Any ideas???

The vehicle is a 1984 300 D Turbo.

Thanks
