Thought you guys might find this interesting. These are the original cam gears as we found them in my father-in-law's '91 318i with 266,000 miles on them. Also found behind the upper and lower covers were all of the original guides, intact and showing some wear although not much more than mine at 125k. The tensioner piston has at some point in the past been updated, perhaps the reason all the timing components are still in good shape after all those miles.
