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

[Fay Kelley]

Hi

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

thanX     Fay
