WHITE SMOKING & LEAKING COMING FROM EXHAUST ON 94 CADILLAC STS

There is white smoke coming from my exhaust in my 94 Cadillac Seville. I am getting crappy gas mileage and my car is running different then usual.
It feels like it is ideling hard & shaking more then the usual.
Is this a head gasket problem?
The car has 172,000 miles on it & I have put way more money into it then I think I should have already!
Just replaced the alternator for the 2nd time this month!
If it is a head gasket, I wont concider paying for it to get fixed, its not worth it at this point! I would like to know if the Liquid Sealent will work as a temporary fix until I can get a new car?!? HELP PLEASE!!!!

    I had a couple more questions for you, I was wondering if this could be the intake manifold.

    Or is something warped?

    I had my intake manifold replaced a while back...



    Also, does that liquid sealent work at all?

    I want to give it a try, but dont want to damage the vehicle anymore then it has already been damaged!

    Have you pulled the oil dipstick to see if there's a milky/light brown residue?

Yes, unfortunately it sounds like you have a blown head gasket. You can check your oil dipstick to see if there is any water in the oil and also check your coolant to see if there is any oil in the coolant. If so then you have a blown head gasket. The problem can only be resolved by having the heads machined and replacing the gaskets.
Please rate me and let me know if this helped.

    The intake manifold gaskets do not require any sealants on them. They are made to go on smooth clean metal surfaces. I am sorry that you have this problem. I lost a vehicle to the same thing. I too get attached to my cars!!!!!

My 2002 cadillac overheats and now the change oil message goes across the dash. When i check the oil it looks fine but the anti freeze is all gone. radiator stays cool but car gets really hot...what could...


Sorry to tell you, these vehicles are notorious for head gasket problems. Sometimes the coolant gets into the oil, and will make the oil look like a milkshake, but not always. The coolant could be burning out the tailpipe, but that is usually associated with some serious white smoking from the exhaust. Or it could be leaking externally and coming out on the ground. no matter which, it is a very serious, and expensive ordeal.

My car smoke alot and no heat


If it smokes out the exhaust it is a head gasket.If it is smoking in the engine area then look to see where it is leaking coolant on the engine.

White smoke when pulling off fron idle


White smoke coming from the exhaust of a vehicle is almost always burning radiator fluid. Go in to a local shop and have them drain the oil and check it for any sign of water. If you are a DIY kind of person, drain the oil into a clear sided bucket and check to see if there is any separation in the fluid(oil is heavier so water will rise to the top).
If it so happens that you have water in your oil the most likely culprits are cracked cylinder heads, or a blown head gasket.

I have a lot of white oily smelling smoke come from the exhaust when I start it after driving over 30 miles at one time. Doesn't do it if I just drive around town. Held a cloth over exhaust and no residue...


I concur with emissionswiz; it sounds like a typical sign of a leaking of 'blown' head gasket and the white smoke could well be coolant+water.

White smoke coming from exhaust, smells like gas


Check the fuel pressure regulator. It should have a vacuum line attached to it - disconnect the vacuum line and turn the ignition on - if fuel come out then that's your problem. DON"T do this while the engine is hot or you could start a fire!
