Question about 2001 Cadillac DeVille

1 Answer

I have smoke coming from both of my tail pipes on a 2001 Cadillac Deville. I can't really tell whether the smoke is gray or white. The car has not ran hot. I did change the radiator cap but that is the only thing that I have done. Please help!

If your loosing coolant when it cools off and draws it out of the resevoir,you know it is water and then maybe white smoke.
You could warm it up without the rad cap and look for bubbles. It will push out air and coolant anyway,so that will be a difficult test.

Dual exhaust issues,should be common to both banks. I would go with coolant and intake gaskets first,may have a crossover in manifold,so you get both pipes effected.

White smoke from the tail pipes, rough idle in start up minimal driving will stop smoke and rough idle

i think you have a water leak maybe the head gasket is going bad any way gasoline produces water and is normal with cold weather.

I have white smoke coming from the tail pipe of my 1996 Cadillac DeVille. Not a blown head gasket, no water in the oil. Could it be my pistons or just needing new seal. Am I burning oil or have an oil leak...

hi... it all depends on the colour of the smoke... usualy blueish smoke will mean it is oil burning and your piston rings may be getting worn if it is black then it might be running too rich etc.. a little bit of water is fine infact usualy it is a good sign that your engine is not running rich or lean so it is pointing towards oil seals... also if it was running rich it would probably do it more when it was cold
