I see a lot of valve coking on DI engines at my job, I also mess with firearms and there's a trend toward nitride coated barrels due to it's properties. I was curious if the OEM intake valves on our GTDI engines are nitride coated by chance if anybody knows.
Just a conversation point, not like I'm going to pull the heads off my vehicle just to install treated valves if Ford hasn't provided some type of treatment, but it makes me wonder. Also, what's the most important oil spec to look at-flash point?
