Smoke out of the Kidney's? - BMW 3-Series (E90 E92) Forum

ni8shadow · 12-11-2009, 07:08 PM

Just got back from my communte. Been raining here and is fairly cold for the area. Anyway, I park the car with the engine still on and I rev it up to 5k...haven't heard her talk in a while

, and after I see some wispy white smoke coming out of the passenger grill

?! Like exhaust smoke but thinner. Is this something to worry about? I am guessing it is the h20 from the rain evaporating from the extra heat of the rev.

thanks

I would not worry about it again unless it happens again. It was probably just the rain evaporating off the radiator.

The smoke sounds normal. But revving to 5k while not moving is something I tend to avoid.

Forgot to mention that.

Ahhh. The radiator. Thanks.

What are the cons of revving up? Not enough air flow? See the guys in the exhaust sound clips doing it.

I dont think airflow has anything to do with it but I may be wrong. All I know is that revving while not moving is bad, everybody says that. I would never do that. A tech guy will have to explain it better.
