So I picked up a friends S4 for a daily but now I noticed a white smoke, someone please tell me its anything else but a coolant leak. also how long do I have before it goes bang of if I just overreacting.

 

when does it smoke? how bad is it? does the exhaust sound sweet like burning coolant. On a wet/cold day, these things throw out some smoke untill they get warm because of condensation in the super hot exhaust.

 

well i started it up warmed it up and only a bit of white smoke came out so I flored it to see and all of a sudden a huge white cloud of white smoke was in the shop, if I dont recall it smelling sweet like coolant but then again I m not a 100% sure. but when i was slowing down to get off the highway it was puttsing around like the engine was stuttering like it was misfiring or something but it was constantly smoking but not excessive but a decient amount.

 

to me sounds like you got a bad apex seal. thats what happen to me on a 91 n/a. it only happens when you start it up rite??? but after it warms up it stops????? yea i replaced the seals and it neer happened again.

 

what do I do to replace the seals?

 

basicly rebuild your motor..........might as well, when did you get the car???.......how many miles does it have ??............ and did your frend rag on the motor when he had it........some of the questions you got to take in before rebuilding

 

sound likes what happen to me when i was racing my 91 n/a something is bad i dont know what but its going to happen soon with your motor ............... is it a n/a or turbo........either way your going to need a heart transplant for your sveen.

 

it is a na s4 88 i think yeah I might as well look for another engine as rebuilds could be a pretty penny.
