Thanks Shawn for the welcome. I joined becuase i'm not very auto savvy and I''m having a big issue with my truck. tell me what you think, my truck dies on the side of road and when i cranked it up there was knocking in the engine. so the dealership tears it apart and says i need a new engine. That a piece of metal got inside and rested on top of the piston smashing and destroying the engine. ???
