Blue/white smoke going up very steep grade ....quattro Digest, Vol 58, Issue 3

 Fay:

You stressed the engine somehow.


 Either got the motor real hot working hard to pull you and the car with A/C on etc.... up the steep hill.

It could have puked coolant out the overflow line.

The A/C will turn off if certain conditions are too hot.
Another is when the throttle is pressed to the floor (WOT - Wide Open throttle)
This will shut down items to get the most power out of your engine.

You either blew all the carbon out of the tailpipe, or burned the spilled oil off the exhaust manifold/pipe.
While working the engine HARD up the hill.

Check all the fluids and their levels while at home.
Keep an eye on the temp gauge as you drive around.
USE the A/C around town to see if any problems come back. Yeah I know its AZ.

Try the hill again keeping an eye on your throttle input and temp gauges.
BACK off the throttle if you are at the floor (go back to 3/4) or downshift a gear.

You may have had several elements which maxed out the motor output
OR came very close to ruining the motor/head gasket getting it too hot.

Subject: Blue/white smoke going up very steep grade ....

I just got back from Phoenix .... my 'check engine' light came
on yesterday ... so I took my car in and had them run the codes
and answer a few other questions.

On my way home (just had oil changed) ... only a very steep grade
I noticed a bunch of white or blue white smoke coming out exhaust.
At that very same time my AC went warm ... I turned it off and when
I was level, turned it back on and no problems at all.

I have driven 3 other cars back from Phoenix on that grade, ChevyS-10,
Audi 100, Audi A6, and on none of them did the AC change on that grade.

I was going somewhere between 60 and 75 up the grade today, I have gone
up that hill at 90 mph and never had trouble before.

Does that sound like the valve seals ?

It turns out the mass air flow regulator or something like that caused
the 'check engine' light to come on ... they adjusted that and the
light went off ...

could *that* cause this smoke on a steep hill?

if it is an engine issue instead of a regular, and it is just up hill, is this
something that I can live with without it getting a lot worse for a couple
of years?

meaning if I don't beat the car will it stay about the way it is?

(and, how high is up?)   LOL
