[s-cars] Smoking after startup

[Lee Levitt]

I wrote about this once before and haven't figured out the problem. My
mechanic went through the car and found nothing wrong. However...it's
*still* smoking (intermittently).

Here are the symptoms.

The car must have been driven and parked, then driven again a couple of
hours later. On this second drive, if I start up, drive a bit and then idle
for 30-60 seconds or more, the car will smoke quite noticeably. It does not
smell like coolant. Instead, it smells just a bit like burnt or scalded oil.
If I rev the engine or put the engine under load, it will clear in about 15
seconds and not happen again. I'm running Mobil 1 10-30 oil and the car has
about 145K miles on it, stock engine.

Help! What could this be? Head gasket? Turbo seals? Demonic possession?

Thanks!
