Hello,
Sorry for the title I couldn't resist . I recently purchased a 1988 GMC Jimmy with the 2.8 engine---sorry it was cheap. It was in good shape and drove fine for two months with no problem, but a faulty starter. I let a friend borrow it and all hell broke loose.

1. The engine started running hot, so she put water in it and kept driving and putting water in it whenever it ran hot or did not start. Needless to say, the Jimmy didn't take kindly to this kind of treatment. The truck now spews out a tremendously excessive amount of white smoke from the tailpipe, enough smoke to cover the truck and obstruct your view. What does this mean, please help, this girl has killed my Jimmy and I need it back.

How much money am I looking at and what damage has she done, this crazy girl also started the car once, while I was doing an oil change and there was no oil in the Jimmy.

Please help, I appreciate any advice.

Thank you.
