If so, I suggest you remove both screws, clean the screws & the tapped holes with brake cleaner & blow dry before reinstalling with Loctite 262 (red high strength) You absolutely do not want it to come completely loose & get caught up in the timing chains. It has happened before.

Otherwise, I understand the plastic facing was firmly attached to the steel guide. Correct?

It could be moved slightly, side to side, but I can?t get it off with just my fingers.

I did take a look at the timing chains and noticed something very strange. On the passenger side there were all these scrape marks on the side of the head. It was hard to get a picture of, but I attached a few that turned out ok. Is it possible for the chain to move this much with a bad tensioner and cause that? That would explain the metal in the oil and the elevated aluminum and iron that the used oil analysis showed. That cam cover did have 9/14 written under it in sharpie while the other side was blank, so maybe it?s old damage that was repaired?
