I have kind of an odd post to make here, but anything you can offer up is good. I am at college and I got some awful news today. My mom was driving my T4R around today on the highway, and she broke down. She described it as the engine started making noise, then lights started popping up on the dash, and she began to lose power. She managed to pull the truck over, and she said that the exhaust was blowing out greyish whiteish smoke. I am pretty far away and I wont be able to check it out for at least a month. I am just asuming the worst right off, blown head gasket. If it could be anything else, please give me some good news, but if not, just confirm my suspisions. Thanks a bunch, Sam.
