Rocker arm failures

Seems to be a trend with rocker arm failures, I don't believe there are any internal differences between model years but it seems that between 80,000 to 120,000 miles some people are starting to see failures. Lets try to keep this simple and if you have had a failure click the appropriate year and comment if you like what year, mileage and what your maintenance schedule is.

Thanks

2008 F350. Failure at 145,000 miles/3,450 hours. Oil every 5,000 with 5w40 Shell Rotella. Fuel filters every 10,000 miles. Followed severe duty schedule on everything else. Deleted at 90,000 miles with DPF-R.

i don't think its driving round miles as much as hours. Everyone drive different so if we see the milage and hours on trucks with lifter issues, it might add some go info to this thread!

I wonder if there's a correlation with idle hours and rocker arm failures. A couple of videos I've seen indicate that not much oil makes it to the rocker arms at idle. If this is the case trucks that rarely idle may never see the problem.

Do you guys let your truck idle?
