I like this new interface. It's nice and clean. Good job guys! Anyways........Me suby is blowing white (well, that's what my mom and sis say) smoke when I stand on it. I'm not loosing any coolant, what might it be? :confused: Could it be oil?

Could be a number of things, but here's one idea (same thing happened to me)!!.This is only if you have an auto tranny though..

Mine was blowing HUGE white smoke & long story short, I replaced the vaccuum modulator on the tranny..Haven't seen the slightest bit of smoke since then!!
Check the vaccuum line that goes to the modulator on the tranny for signs of tranny fluid inside it..If your modulator is bad, the vaccuum line will suck tranny fluid & it ends up going straight into your intake manifold along with your fuel..Hence the white smoke..

If your not losing coolant, then it could be running rich. That will also produce white smoke of a constant nature.

Sorry, GD, but I just went through a problem where my wagon was running very rich. (I have an air fuel ratio meter that showed this)
Not to "dis" your reply but
running rich produces black smoke.

Ted, if your car sits for days between use or you only use it for short runs, moisture will build up in the exhaust components and this moisture will be
dispelled during periods of high flow rates (read -standing on it) This produces white smoke as white smoke is an indicator of steam aka vaporized moisture. (note: Burning ATF will also make white/ble smoke as Slag says)
This steam is of no concern if after a thorough warm up the vapor ceases. Be forewarned your exhaust may rust through faster though.

Possible leaking master cylinder, brake booster. Engine could be ingesting brake fluid, which smokes white.
