Ok well I blew my heas gasket along with my water pump and a few of my coolant hoses on a road trip, I put some bars head gasket fix in it to get it to a safe place. I'm about 400 miles from home and pretty broke. I can get all the parts I need pretty cheap but I'm worried about the chances I cracked my Block/head. How Often dose the head warp when the gasket blows on the 7m? It runs but I know I have a fouled plug now cuz I have a miss fire and it smells rich. The bars stopped the smoke tho. Any help?
