I have a 98 Grand Prix GT V6 3.8 with 176000. My cars engine caught on fire due to a oil leaking into a spark plug. Since it has been at the shop I have had the plugs and wires change, o rings, all the gaskets, a new valve cover, and a cylinder head replaced and my car is still blowing white smoke. What else could be wrong?

How long have you run it? Sometimes if the cat converter gets coolant in it, it will take a hard drive to get the cat hot enough to burn it out, otherwise it will smoke for a while. Did you do both head gaskets? Why was one head replaced?

I am not sure how long they ran the car, and yes only one head was replaced, I was told the other did not need replace.

What about the head gasket? One head should never be done without the other in my opinion
