Spark plug issues were only the early years. V10's never got cam phasersI thought there was spark plug/ cam phaser problems like the 5.4?
Very reliable engines. Many have no issues going 500k+ if properly maintained.
Yep. Know a guy with one of those in an F550 flatbed that's always overloaded - yet's he's turned over 400,000 trouble free miles so far.
Mine has only 66,000 miles on it so far but also so far nothing but oil and filter changes done to it.
The only issue I can think of for that particular application is cracked exhaust manifolds. If you are constantly loaded heavy and have a heavy foot you will crack exhaust manifolds. But that goes for any 3/4-ton and up gasser...
Sounds like the perfect excuse to buy a set of headers...![]()
