[s-cars] Smoking is hazardous to my sanity

[Walsh, Edward]

Thanks Bjorn.

The smoke does stop (almost) immediately after startup (less than 30
seconds).  Once its gone, it is gone for good.  Also, Paul mentioned Valve
seals.  I don't think its the seals because, from what I have read, the car
should start smoking after a long downhill descent (causing a high vacuum
situation).  It does not.  I still don't think its a HG because I have
driven about 2,000 miles this way with no coolant or oil loss.  Plus, the
car runs perfectly.

General surfing of the internet keeps pointing to white smoke plumes as a
sign of a bad turbo....

This is why I am going looney!

Ed

More smoke in cold weather=coolant leak. Simple math.. Even if you don't
have any measurable loss of coolant, the signs are unmistakable.
I'm just a bit confused about you not smelling any coolant in the fumes,
but you might have the red coolant stuff? (I don't know what that smells
like.. Anyone?)
Excessive fuel (at least the amount that makes any smoke!) will be dark
gray to black, and you will make a smoke trace. (or it will at least
hang in the air for some time..)
Sad to say, but you have a leaking gasket somewhere, probably the
headgasket. A crack is also possible, (haven't I read about that
previously here??) and that will certainly behave just like you describe
it. I'd get one of those moisture measuring thingys that will replace
the spark plug, and check one cyl after another for moisture. (You'll
have to let the car stay for at least two days for each cylinder.)
I don't think the turbo is leaking, cause then the smoke would stop
immediately after startup.

Just my .02c..

'92 S4  Ahh.. Defa Warm-up is pretty nice! :o)
