2012 w/ 92K miles. Maybe an occasional chain clatter on a cold start, but no real issue. I might be hearing something else, as well.
I'm about to do them preemptively, however. That is really just because of the known issues, my plan to keep it until it rots in place, and it will make me sleep better at night if I am 25 miles from pavement. Also, I guess because working on that rig is my relaxation and I have a Rover specialist about 4 miles from the house who is good to me. Might pay him for 5 hours of shop time to yank it and put it on a stand for me to work on.
Planning to yank the engine out the front, do the timing chains, guides, accessory chain, walnut blast the valves, water pump, both crossovers, rear main seal, either replace or send the injectors off for rebuilding, add an oil catch can and any other sundry items I stumble along in there, as well as give it a good cleaning. Hoping that will set her up for another 150K miles or so.
Other than the air struts and compressor, pretty much every consumable item will have been done on the rig at that point.
ETA: Debating replacing the cam sprockets and oil pump while it is opened up since those cannot be accessed without breaking it down again. Interested if anyone has any thoughts on those.
