I was going to stud it and Ford says if I do anything to the engine it could void the warranty including the studs. I had planned on doing a lot to the engine like BPD oil cooler, EGR cooler, exhaust, Coolant filter, oil bypass, studs,switch to ELC coolant etc since my warranty was going to end in 2014 but now since I've had a lot of of problems with this engine over the years and this time it completely died. I've lost a lot of faith in it. I had thought the problems were fixable with what I planned on doing but this problem could happen again at 146,000 miles even with all my upgrades.I'm not sure I want to sink a bunch of money into it especially since I'll have a new two year warranty. I'm thinking about doing nothing to it and just sell it or trade it in a year or two but definitely before the warranty is up. It's just left me stranded too many times over the years and I go way overboard on maintenance to have the problems I've had. Heck in the last five months I've got a new intake manifold,alternator,batteries,thermostat,oil cooler,turbo,egr cooler,egr valve and I'm sure more I cant think of. I see a 6.7 in my future if Ford doesn't try to screw me over on this one. I just hate the the thought of more truck payments but I hate the thought of breaking down and no warranty also. Sort of damned if I do and damned if I don't' you know.
