I won't hold my breath.
Until then it didn't happen, except in the imagination of some crackpots spreading Internet rumors.
Did you take pictures by any chance? Or just gonna stick with the "reuputable builder" story?

I'll throw my two cents, i've owned two F-250 a 1999 7.3 & a 2008 6.4, i changed the oil on my 7.3 every 3,000 miles & 5,000 miles on my 6.4. I've used ROTELLA, DEL-VAC, GTX, MOTORCRAFT, & DELO, whichever was on sale & have never had an engine problem. BTW most of the time I used a FRAM oil filter
