Your car has white smoke coming out of the exhaust It is a 1997 Buick Regal LS and has around 95000 miles on it It smoke a little after it starts and goes away after about a half a hour in idle?

Answer 1

White smoke from the exhaust is one of two things. In the winter it can be nothing more than condensation. But it can also be a blown head gasket or a cracked head. You say it lasts for an hour, so this would make me think you have an internal engine problem such as a blown head gasket. Does the white smoke smell sweet? Are you loosing coolant with no apparent leak. Do you notice the oil level has increased above the full mark? Is there a white foamy substance on the underside of the oil fill cap? Is the engine overheating or running at a slightly higher temperature than normal? If you answer yes to any of these, you have a serious problem. Stop driving the car and have it looked at by a professional. If you keep driving this car with a blown head gasket you will ruin this engine.

: The smell is kind of like deisil or something not really like burning coolant though. (1) On December 14, 2008 at 00:37 am Hunt3r [0] said:

: I flushed the coolant, changed the oil, replaced a valve cover gasket and tried putting sealant restorer into the oil and coolant. Yesterday I put a gallon of gas in it and some engine cleaner in the gas. After this it stopped smoking for a while but today it starting smoking when I started it. The coolant is still clean and oil looks normal. Also it seems to run well and doesn't overheat or have power loss. this is my first time using wiki answers so i didn't know where to write this, its also in discussion
