My son changed the head gasket and manifold gasket when he borrowed my truck, he said it blew the head gasket. So, when I got it back it kept overheating, so I completely flushed the system and burped it thought it was fixed oh yeah and I removed the thermostat. It did okay for a few days then I noticed that it was overheating again and no heat from heater. I pulled over to let it cool off and was going to start it and it made this grinding noise and acted like it was vapor locked. I kept bumping it over and it finally started got it home and the head gasket was blown again. I flushed the system and used blue devil, it worked beautifully for 24 hours, and it made the grinding noise and acted vapor locked again and blew gasket. Any clues what could be going on? I can't afford a mechanic so I'm doing it myself. I just pulled water pump and it has oil coming from bottom right bolt hole. please help.
