There goes my head gasket maybe

[joecassie]

What does it mean when I start up my car and there is a little bit of white smoke coming out of the exhaust, and I just put a whole new exhaust system on it yesterday. Is it something serious? Or just caused by water?

How new is the exhaust? Used, or brand new? Mufflers, res, cats, etc? Did it blow smoke before you installed the new exhaust?

My exhaust smoked when I first installed it. I was worried. So I drove it a little ways and the smoking stopped.

all brand new just came out of the shop

Headgasket failure usually involves some combination of the following, besides burning coolant:

Overheating
Oil and coolant mixing - milkshake
Compression drop in affected cylinder(s), making for a loss of power

Upon startup water condensation will cause some white smoke. Once the car / exhaust is nice and hot it should be gone.

ok and my car will die after i turn it on but just once ND fter thT ITS fine. is that bad

Sounds like your exhaust is just burning off the oils & grease that is on the outside of the material. It'll stop doing that eventually.
