Consumer Description

The vehicle experienced a rough idle and white smoke blowing out the exhaust on a cold startup. It did have coolant loss over a period of time with no visible leaks. I waited until I got a check engine code that revealed a misfire in cylinder 4. Upon further diagnostic testing it was revealed that the head gasket was blown between cylinders 3 and 4. I paid for the repair out of pocket only to see that this is a very common issue with the 1.5 turbo engine.
