6.7 engine replacement


Staff member
Vince, do you think that TSB 12-11-11 applied here? I see it was a 2011 F-550.

Is there any physical difference between the factory supplied block and the "long block" that is directed for replacement? Do you know if there is any documentation on the design change to the head that prevents the valve insert from releasing?
Yep, thats the one that I followed. You get paid 18.3, and it took closer to 30. Only difference I saw was different glow plugs are used (overall same length, but seat to end of glow plug is shorter.
