hollywoodj10 Posted October 8, 2007 Report Share Posted October 8, 2007 After solving my overheating problem my 98 Seville is letting off alot of tail pipe smoke. What could be possibly causing this issue? Do you guys think this is a head gasket issue of something else? Link to comment Share on other sites More sharing options...

hollywoodj10 Posted October 8, 2007 Author Report Share Posted October 8, 2007 yes its white and it smells a little like coolant but dont quote me on this. It comes out real heavy while im in park but it eventually stops once i actually start driving Link to comment Share on other sites More sharing options...
joeb Posted October 8, 2007 Report Share Posted October 8, 2007 you have to ask yourself why the cooling system had an excessive amount of sealer? flushing it may have helped your overheating problem but now you may have a small internal leak to deal with. keep an eye on your coolant level. you were not driving the car a lot due to overheating so try and put some miles on it and see how it behaves.

BigCat83 Posted October 8, 2007 Report Share Posted October 8, 2007 If you're worried about the possibility of headgaskets/headbolts, take the car out on the highway and get on it. Watch the Temp Guage; if it climbs rapdily or spikes you have serious problems. You may only have some heavy condensation on initial start-up.

Ranger Posted October 8, 2007 Report Share Posted October 8, 2007 Sounds to me like you already have serious problems. Do a cylinder pressure test to confirm it. Link to comment Share on other sites More sharing options...
BodybyFisher Posted October 8, 2007 Report Share Posted October 8, 2007 Stick a fork in it it's toast, no doubt testing will confirm the worst. If you decide to get it fixed make sure they timesert the block. Your options are 1) head gaskets with timesert (+$2,500, 2) Rebuilt engine (Jasper-do search), and 3) Scrap Yard engine a risky choice). I hate to sound negative I do but at this point you need to do some diagnostics, 1) the hydrocarbon test and 2) a pressure test, good radiator shops can do this.

I was hoping that it wasnt the heads so soon. I was still shopping for a engine but didnt want to rush into buying one. Ill get the hydro test done and give you guys the update this weekend. Thanks for everything Link to comment Share on other sites More sharing options...
