Question about 2002 Buick Century

3 Answers

I have a 2002 Buick Century and soon after I start it white smoke comes out of the exhuast pipe. I don't believe coolant is getting in to the oil, so I was just wondering if I can keep driving the car without damaging it further.

If the white smoke comes out for 15 to 30 seconds your engine is ok. Condensation does build up inside the engine and as well as the exhaust and will burn out in that amount of time. If the white smoke is continuely extracted from the exhaust pipe you do have coolant leaking through the head gasket

Hello and welcome. this is usually caused by one of two things, the lower intake gasket is leaking coolant, or it has a leaking headgasket. in most cases it is just a bad lower intake gasket. to answer your question, driving with this problem can cause severe engine damage. the problem is coolant in oil causes damage to the engine bearings, causing a major engine failure. it would NOT be a good idea to drive until this concern is repaired.

From your description this may indicate a head gasket leaking into one of the cylinders.As far as driving it in this condition it would not be advisable.

White smoke Audi 2.0 non turbo is this connected to excessive oil consumption is a 60k mile engine A4 reg 2001.


White smoke is usually coolant burning, but you say no loss of coolant, so must be oil burning. PCV is possible fault, especially since you say smoke is intermittent. Part itself should be cheap, less than $20. One your car I believe it is located in a pipe running from intake to valve cover.

Milky oil dipstick, white exhaust smoke, coolant in spark plugs


*White milky oil on dipstick = coolant in oil.
*Coolant on sparkplugs = cracked head or blown head gasket
*White smoke = burning excessive oil in the cylinders, which can be caused by a number of things including valve seals, cracked head or blown head gasket.
***All three of these symptoms together, however, means its the head or head gasket. Both are costly but better the head gasket than the entire head.

Is there a squealing noise like the pulley may have locked up? Make sure you don't have wiring getting hot.Check all areas near the exhaust and at the firewall area where the EGR piping comes off the exhaust.
Make sure nothing is laying against the exhaust or catalytic converter. don-ohio

Car over heats both fans working and i have a new thermostat.Even checked water pump to make sure it's ok. very frustrating1!!!!!


Flush coolant system out. If this does'nt help check for white smoke coming out of exhuast while its running.White smoke from exhuast would mean that coolant is getting into one or more of the cylinders,which would mean more than likely a blown head gasket.A blown head gasket would cause it to over heat.If you are loosing coolant and don't no where its going would be good sign that its blown.You would need to proform a leak down test on each cylinder this would let you known which cylinder is the problem.

My service soon and low coolant lights are always on. I do forget to check the coolant. this morning, my car was running very rough and I stopped at the service station, and noticed that the car smelled...


Check your exhause smoke. If it looks like steam, then more than likely you could have a blown head gasket which would make the lights come on. If there is no steam in the tail pipe, then check your oil to see if it looks milky after the car has been running for a while. That means you have water in the oil. This could mean you may have a cracked head. If these things check out ok, then I would find the leak for the coolant.

I have white smoke coming out the exhaust pipe


If you are having a lot of white smoke all the time the car runs then check for coolant mixing in with the oil,look for water in the oil when you check the oil or milky brown oil. This produces a white "steam" that is very thick to come out of the exhaust. If your engine temp. gauge is very high and over heats you probably have a blown head gasket. If it has a bluish tint look it may be burning oil. Indications might be how much oil is currently in the car i.e too much oil, or if there is a leak in the line you may be adding a bunch of oil over a short time. If it is only when you first start the car and the engine is cold, then it may be that your valve seals are bad and need replacing. Hope this might help or at least give you some ideas..

I have an 02' Jaguar xtype sport 3.0. For about a year now at start up it has alot of white smoke coming from exhaust, its not o/h. Could this be the cc


Hi Kevin,

White smoke is indicative of water (or coolant) evaporating in the heat put out by your motor. The good news is that it stops. The likely cause is condensation that formed over night is burning off.

So, riddle me this:

Do you experience loss of power?
Coolant levels inexplicably getting lower?
White froth on the dipstick?
Oil in the coolant?

If not, there's probably nothing to worry about. But let's err on the side of caution. Have a compression test done on all cylinders. This is the easiest, cheapest and fastest way to tell if a head gasket has failed.

Best regards
Mike

White smoke is not good. But it may not be what white smoke typically is, which is coolant leaking into combustion chamber... but rather a backfire dislodging exhaust particles.

Get the error codes read and you will be able to know where to go next.
