3v Problem Areas
Just recently picked up a 2008 super duty with the v10 and have been reading about some of the problems they have. Aside from the common exhaust leaks and factory spark plugs breaking, it seems like they had issues with the roller rockers failing during some years, and also suffered from insufficient oil pressure to the top end, especially at idle. Are either of these issues (or any others) something I should be concerned about? Did certain years have issues or is it all 05 and up engines? Thanks

that’s what I thought too but after reading some more, it seems like the top end can have issues, especially with high idle time

I'd say keep good oil in it, change it ahead of schedule, don't beat it all the time, and it will probably be fine for you for a long time.
Keep in mind that a lot of 5.4s and most 6.8 V-10s saw hard lives with less than stellar maintenance.

while the OP states 2011 to 2013 that thread pertains to the 3 valve 2005 and newer .and in all regards since the v10 is really a 5.4 with 2 extra holes, sharing a lot of parts,what goes wrong in a 5.4 can possibly go wrong in a v10

How many idle hours is your truck showing?
I always refrained from extended idling but if it was necessary I did the high idle mod to help compensate some.
From what I read it is a real issue but to what extent is hard to say.
