    97 Deville overheating and smoking

    Hey guys, my 97 Deville has been overheating. It is blowing white smoke out of the exaust and I can smell antifreeze. I'm thinking it's probably a head gasket. How much do you think it will cost to get it fixed? What else do you guys think it could possibly be? How much do you think it will cost? I just don't want to go to a shop and let them know I have no clue what I'm talking about and have them soak me.

    I understand what your going through. a friend of mine is talking to me about his everyday, everytime he looks at me. The dealer is telling him $5800.00 for a new engine. we are trying to find a cheaper way. someone hinted some time ago that some bolts are probably loose and could be tightened if the head isnt cracked.

    your speaking head gasket so you may be able to just tighten bolts. {hopefully}

    Sorry I couldnt answer your question very well.

    "Thats gonna be a rebuild."

    pretty much , seen numerous times where coolant that gets into the oil system and messes up main bearings , ususaly less than 4k from the head gasket change

    tho im talking 6.x diesels and 2.2 chrysler turbos , northstar may be diffrent , and he may be lucky and only blew the gasket between a combsution/waterjacket seal , that would limit the ammount of coolant down to just the ammount entering past the piston rings which isnt as much , a few times in this case we got away with a headgasket job alone

    at any rate he probably shouldnt run the engine till he knows what is going on

    It has about 96,000 miles. I will have to check the dip stick next time I am outside (at work right now and car is not here) but last time I checked the oil there was no milky substance on the dipstick.

    I should also note that it doesn't smoke all the time. Only for a minute when I first start it up for the first time of the day. After a few seconds, it stops smoking. And if I shut it down and start it back up, it doesn't smoke anymore. Even if it sits for a few hours, it still doesn't smoke. Only smokes for about 30 seconds on the very first startup of the day.

    you would know if need your head gasket needs to be replaced, beside by checking the dipstick, it would run hot whenever you try to use ac/heater, and also you would notice that if you floor it, it won't go anywhere. Also it would cutoff alot. It would also be cheaper if you get a hanyes manual, and do it yourself, it's not difficult to do, it would save you thousands, if that is the problem.
