Bought this truck over a year and a half ago with little to no problems. Just recently the truck started to run rough so brought it into Firestone to see what the problem was. Problem they say is head gasket. Tried Blue Devil and it seems to be working alright. Need the truck for pulling and I know not to be doing that until we get the head gasket fixed. My question is, is it worth keeping the truck? Can find someone privately to fix the truck but the amount of money that is going into it, is it worth the money to keep?
