[s-cars] RE: Did you fix your car?

Hi Ed;

If you suspect the turbo seal, pull the Michelin man hose and look for
excess oil or coolant inside it. There is usually some oil inside this
hose.

It almost sounds like a condensate cloud. This is no stranger to us Canuks
on winter days - the car will "smoke" a long time at idle when cold, but
driving off warms up the exhaust and the condensate cloud vanishes ( except
at 40 below, but that's a different story). Unless your engine is making a
lot of water ( or pulling coolant) you shouldn't get this on a warm day,
which brings us back to the coolant issue.

Hi Jeff, thanks for asking!  I have CC'd the list, maybe the group can
help...

To answer you question, due to an unavoidable circumstance, I missed my
appointment with the dealer... so I am still in the clouds, so to speak.

Here is what I know:

-In the 500 miles since this started, the car has not used any
coolant(perceived).
-The car *may* have used a little oil (< than a quart over 2,500 miles
since
last change)
-Spark plug deposits appear normal.  Not too clean (burning coolant), not
too dark (burning oil)
-There is no coolant in the oil or vice versa.
-If I start the car in the AM, and just let it idle, the smoke/vapor will
gradually  increase, to a point, and then hold at a constant level of
output.  Out of sympathy/embarrassment for my neighbors, I stopped idling
the engine after 3-4 minutes and drove off.
-If I start the car in the AM and drive off (slowly) after a 10 second warm
up, there is little to no smoke/vapor at all.
-The car is otherwise flawless.

The vapor/smoke dissipates quickly.  Maybe after 15 feet of drift in a
light
breeze.  It is white/light gray in color.  The total size of the moving
cloud is roughly the same as my car. If I hold my hand to the tailpipe, the
exhaust fumes are cool and my hand stays dry (not oily or wet).  The
smoke/vapor is almost odorless.  It does not have a sweet coolant smell,
nor
a foul burnt oil smell or raw fuel.

-Any ideas of what is burning?

-I don't think its a head gasket because the car doesn't overheat, there is
no apparent mixing of coolant/oil, the plugs appear normal, the car pulls
as
well as a similarly equpiied URS, no significant consumption of oil or
coolant.

-Could the turbo have blown a seal allowing traces of oil or coolant into
the intake track?  I ask specifically about the turbo because the all
started soon after I installed the MTM 1+

THANKS!

Ed

Hi Ed,

Curious to learn what you found with your car.. did you get the white smoke
resolved?
