We my ol blue truck has done something. Blowing steam out tailpipe and water running out end of manifold where it connects to the muffler. Im thinking head gasket. It didnt overheat or anything i stopped in the store to put some gas in it and when i came out it was steaming like crazy. Is that pretty costly. Shes been a dandy for 2 years but if it cost alot i might ship her to the junkyard because the heater dont work and mirrors are ripped off and it dont have a straight piece of metal on her haha. If its a simple fix i might fix it but i aint puttin a 1000 dollars in it ill just use that 1000 + junk price and get me another beater somewhere.
