Just broke a #7 intake valve spring in a 2016 6.2L at 30k miles- valve dropped into piston and cylinder wall. New engine is going in next week. In a quick search, I see broken valve springs aren't that uncommon on the 2014-2018 6.2L. A few questions, though: 1) Why is it so common on the #7? Valve springs and valves broken. Somehow AFM related? 2) Have there been updates since 2016 to the valve springs, or to anything that might be contrubuting to this? I'm wondering if I should expect any different results from the replacement engine. 3) What should I look for in the way of additional warranty or anything else for having to deal with being out a truck for a couple weeks, towing fees, and now having an engine replacement black mark on Carfax, etc., potentially impacting resale? Or maybe the majority see a newer engine as a positive thing??
