What I refer to is the head bolt stretch issue on some 6.0 engines, not emissions related issues, thought I'm sure there are some...
There was a heat treat issue with some head bolts that allowed them to elongate over time, resulting in perforated head gaskets. Not all engines are impacted but some are and like I said, the only way to pull the passengers side head is to pull the cab. The rearmost 2 headbolts cannot be removed any other way....
I suspect the 'elongation' is accelerated by hopping up the engine as well and that is a popular thing to do today.
Glad I have a 7.3 Navastar OBS. Not the most power but pretty bulletproof.
Ford's overhaul / maintenance issues began when they shortened the hood and set the engine back under the firewall
Ford has a 'better idea'...lol
