Hi..
 
thanks for the quick answer. Actually my problem seems to be worse than yours, not only do I hear the noise that sounds like hydraulic lifters bleeding down u describe, what bothers me the most is the loud cranking that occurs when i steer to the left / right.
 
I own the car for three years and that's the first problem I ever experienced with it, after warm up it runs like a charm.I was very concerned when it start happening and took it to the mechanic right away but they couldn't pinpoint the problem. This is my third winter with it and never had this problem before, i guess that's because this one(season) is really a bad one.Really cold.
 
In any case you put my mind a bit at ease if ur mechanic reveals that he never heard of engine damage because of that.have about the same amount of miles and always use factory oil and filters whenever I do an oil change. I'm gonna keep on driving it like that and see what happens when the season's over.
 
I'd like to thank u for the input, very thoughtful . Keep me updated if u have further info. I'll do the same here.
 
A great year to you and your family.
 
Tony.

It seems I had same problem with you.Brought car to mechanic ,sit in shop waiting for a cold starting in morning.Next day , Called in and he said everything fine, starting very quiet, no problem.Then he drive my car parked outside.It's 32 F outside. In the afternoon, I came to get the car, I start and noisy again.He look at and pinpoint right away that noise came from steering wheel pump,not the engine.No need to worry. Day before car parked inside shop, it's heated space so everything is normal.
Took car home, next cold morning, check again and noise is exactly from steering wheel pump, weired hummy noise when I steer left/right.Tap / warm with hair dryer, still noisy, but as usual dissappeared after couple minutes.
Note that my car parked in unheated carport, And can't explain, after that morning, the noise dissappeared forever.Every thing normal now, 24 or 28 F still no noise.
Can't explain but happy.Share this experience with your guy. My car was a 2001UL / 80K.
