Would you buy an 04 6.0l that's already had the headgasket replaced?
It's an F-250 with 80k mostly highway miles. Headgasket, EGR, and some other stuff were replaced by the dealer at 60k. The truck in question seems like a decent truck, seller is open and honest. Haven't run an OASIS yet.
I'm going to use it initially for towing a bumper-pull 2 horse trailer, about 6k#. Later, a gooseneck horse trailer weighing about twice that. No intent to mod, plow, or lift it.
I've been reading/learning what I can but I'm still trying to find the answers to these questions:
1) If a 6.0 has had headgasket work done already by the dealer, is it going to happen again? (In other words, does the dealer just fix what's broken, or do the fix the root cause so that it won't happen again?)
2) Is there work or reliability mods that I could do to prevent it from happening again?
3) Are all 6.0's with headgasket history just best to walk away from as a buyer?
