Yeah, I probably should replace them with the updated versions, but they ain't cheap and I am. I'm not even sure that cleanign them would necessarily make a difference.

I have the clatter isolated to the IMS/crank tensioner and I was hoping to just take that one out and clean it without having to go through the cam lockdown drill.

As an aside, the Pelican DIY for replacing the IMSB doesn't require the cam lock, it just uses set screws to lock the IMS before the tensioners are released, so I thought maybe I could get away with just removing one without the cam lock.

Other than the annoyance, is there any long term damage being done by the start up clatter?
