First time posting here...great newsgroup!
I have a 2001 Chevy s-10 pickup, 4 Cylinder 2200 SFI engine, ~153,000
I am having serious problems with my truck. Here are several symptoms
that all occurred near simultaneously:
1) When I first turn the key, the engine would turn but not sound
"right". It's hard to describe...but the initial try sounded harsh -
like a starter that doesn't engage the flywheel. The engine would
engage on the second try.
2) There is a nasty electrical problem. If I turn the left signal,
both the left and right rear directionals actuated. I also hear the
fast clicking from the front directional.
3) When I tried to start the engine, I notice smoke come out of the
4) After struggling with the truck for a day, the engine now doesn't
start, the starter just spins.
I took off the air duct and you will see the oil in the air box just
before the throttle body. You can see in the second pic where the
smoke came out of the throttle bottle. There is also evidence of oil
on the spark plug.

Has anyone else had this problem? I think the big question is why oil
is getting into the combustion chamber - and whether this is related
to the electrical problem. Something has failed but I am not sure
what. I should also note that I am pulling a P0420 (catalyst) error
code - which is probably from oil junking up the 02 sensor. Any
insight is greatly appreciated, TIA!
