thanks, the head bolts came loose when the car ran away from me the other day and the temp was 280+. From that day the car doesnt work right, the head bolts are tight . Around the sealing surfaces of the head it has some paste around it. I would try to clean it with alcohol and put some rtv on it and try it out again. I will keep you posted but its going to be saturday or sunday intil I try it out. my pull cord stop working. thanks
