Stick a fork in her, I think it's done! Daughter's 1995, 3.4L with 192K just started smoking a few days ago. I had been doing a little work on it over the past few weeks since it had been hard to start and running rough. New fuel filter, air filter, injector cleaner, plugs and plug wires. Anyway, today went out and started it, after a few minutes white smoke starts coming out of the tail pipe. She says it gets really bad when she is driving and then comes to a stop. I know it's burning coolant because I checked the res and it was low with no signs of a leak. My question is this: with this type of motor and the miles that are on it, is it most likely a bad head gasket, cracked block or cracked cylinder head. If it's a bad head gasket I might try to fix it myself. Any suggestions!?!?
