I have a 2008 ford f350 with 92000 miles on it. I have recently had to lock out the cam phasers, replace the transmission lines for the external filter, and replace the starter. It just started to burn a little antifreeze, should I replace the head gasket or just swap the engine, I would imagine those head gaskets are a nightmare and if I was going that deep I would probably want to replace the timing chain and cam phasers at the same time.
Before even thinking about replacing the head gasket or swapping out the motor, check the head gasket and make sure it isn't blown.
