there more then usual white smoke coming off the exhaust. I have a 1990 with ss dual exhaust. is this normal? and it smells like oil when you drive behind the car. any info would be helpful
thanks

 

how much is comming, white smoke usually indicates burning coolant, its possible that your coolant seals are starting to fail which can only be truely fixed with a rebuild. there are many threads that cover how to fix this with radiator sealer stuff (not sure about the exact name) and it seems to work pretty well for most people as a temporary fix. -alex

 

just a little when you start it up. when the engine warms up it doesnt smoke

 

thats pretty normal i think most fc do that, thats either left oil in the chamber burning off or just cold

 

IF it smokes when cold, then the smoke goes away, thats just signs of an older motor..

 

before i got my cats in i smoked mad dark blue after high rpm shifts.. the old owner thought it was coolant leak, but it went away after i changed my cats.
ive heard alittle smoke on startup is okay.. hell my brand new honda would smoke on startup.

 

If it smokes white(sweet smell) when cold it means a blown/cracked coolant seal. When it is cold the cracked coolant seals allow coolant to seep into the chanber.........once the car warms up the seal expands and coolant no longer leaks in. In order to get to the seals ou need to tear the whole engine apart so most people will just rebuild it while it is all apart................
