I was on the highway and my car started go slower and slower and then i pulled over and it died and started to smoke white and now it wont turn over
water going right though it out the exhaust, put stop leak but it still losing water
Temp getting hot,and then cooling off.White smoke coming from exhaust.Used block sealer from part's store.Seem's to be working so far.
Scraped the car after the block cracked. It was cheaper to buy a newer used car then repair. The car is 22 years old. Just getting to the head would cause other parts to break adding to the price.
white smoke out of tail pipe
White smoke and radiator hose bad

I had hydrocarbons in radiator overflow, plus white smoke coming from tailpipe,it was over heating and loosing coolant.I used blue devil block seal on it two years ago and it took care of it ever since.
started it up to leave for work it was running rough so i give it a little and it started blowing smoke out of the tail pipe no warning at all the head gaskets was going to give out
