White Exhaust

When I start my car up on a nice warm day I can still see white exhaust smoke coming out from the exhaust tips. It doesnt leave any white residue behind. The car seems to be driving fine. This white smoke doesnt really have me concerned too bad but would like to know whats going on?

Anyone have any ideas?
 


sounds like your burning oil its kind of a hit or miss type thing with 3800s out 2007 GT burned oil at 40K miles but my 1999 GTP doesnt at 176k miles
 
they probably already replaced the LIM already on your 99 with the aluminum one it should only have to blow once before you do that and than you will get alot more life out of them

the white smoke usually means coolant getting into engine and the usual culprit is what I had said to asite the LIM gasket tends to go out pretty early regardless of mileage just because the dexcool eats the **** out of them

Smoke color

Blue = Oil
White = Coolant
Black = Gas
 
couldnt that mean you have a bad LIM gasket and oil/antifreeze is leaking through to the exhaust?
 
i would be amazed if my LIM had already been done, my buddy with a 2002 monte carlo ss just replaced his LIM and his car has white smoke coming out his tailpipes on start up i mean white and blue smoke are hard to distinguish sometimes
 


I am Catless now since my header install.

LIM gasket were replaced a year and a half ago so they are good but I will still check gaskets out.
