Courtney,
Sounds like a coolant leak to me. Probably the easier leak fix would be a
head gasket replacement (if the leak is there), or a turbo replacement (- if
it's used you can probably get a turbo for cheap (www.car-part.com)
Engine leak: Try this test: get a fair sized pickle jar - without the
pickles in it of course - and hold the open end towards the tailpipe
when it's emmitting the plume. When you get a fair amount of condensation
in the jar, put it in the freezer overnight - if the condensate has frozen,
it's water. If it is unfrozen, it's coolant. If it's green, you didn't
wash the pickle juice out before the test .......You can also try a
compression test with the engine hot - large variations even within the
allowable pressure range can mean a coolant leak. Then there's the usual
checks - oil in the coolant, water in the oil, whitish discoloring of the
spark plugs. After the car has run at operating temperature for a while,
pull the plugs and hold an inspection mirror over the plug holes - fog is
coolant leakage into the cylinder.
All in all, it doesn't sound good. Letting an engine coolant leak go will
eventually destroy the engine, as the coolant washes the oil off the
cylinder walls and enlarges the bore through metal:metal contact.
Cheers!

If It's white, not blue or black, are you sure it's not just
condensation from the exhaust? If you're not losing coolant or oil or
getting oil in the coolant/coolant in the oil and the car performs OK I
wouldn't worry.

My '91 Audi 200 Turbo usually emits a cloud of white [not blue or black]
smoke on initial startup each day. After warmup this doesn't occur at
startup. It has about 335,000 miles on it. I'm assuming this probably
has dire consequences if it's cause is not determined and repaired.

From worst to least damaging, what are the possible causes ?

By priority of easiest to do, what should be the testing sequence to
determine the cause ?

Any hints on conducting tests would be much appreciated.

Gratefully,
Courtney

Probably oil from the turbo bearings burning off directly into the exhaust.
Looks just like the white smoke from stunt aircraft!
Just wear and tear, could be like that for ages. Worry when it does not stop

White smoke is oil. Black smoke is gas. You get white smoke when the
oil leaks past the valve stem inserts onto the valve seat and burns
off during the first minutes of engine run. Then engine heat swells
the parts and prevents oil from draining past.

You get black smoke after start up but usually reappears each time you
accelerate from a stop when your rings are worn out and sometimes
continuously during driving when the rings are really worn bad.

Either way all these things are typical of an engine with the number
of miles you have on your car and no amount of oil changes will
prevent it. Its worn out and you need a top end job at least. Best
have the whole engine rebuilt while it down though or junk it and
start over.

Dear Scar,

What do you mean by 'top end' job, and what's the difference between it
and a total rebuild ?

Thank you.
Courtney
