So I was driving down the interstate today and I noticed that my temperature was very high. I figured I could make it to the next exit in order to add water (which I had done 2 days prior). I didn't make it. My car started making a clacking noise and then proceeded to stall. I opened the hood and smoke was pouring out of my heads with a smell of burning rubber. I called my dad up, and he brought some water with him. We filled the radiator up and tried to start it. Water started shooting out of the bolts that hold the top of the engine on. So we tightened those bolts, and the car wouldn't run. I think I screwed the engine up. Any input on this would be great. I would hate to think I would have to rebuild the engine. I would much rather change the cover and replace the gaskets. Does my car sound beyond repair?
