Maybe if Ford didn't try to develop their "OWN" fuel and electronic systems for the 6.0 they wouldn't have such a HIGH warranty cost.
From what I know International is using the VT365 (6.0) and has had very few issues with it. The international is using a 235hp/620ftlbs of torque engine where ford is using 325hp/570ftlbs of torque.
HUMMM Wonder why they cannot keep head gaskets on these engines?
Ford is pushing these engines at 95% of their peak MAX HP.
Honestly in my opinion Ford hes to eat the warranty costs since they fooled with the design of the engine.
