Re: R60/2 Question on rocker arm movement.
On my /5 I gave up trying to adjust one of the rockers and bought a used set. The sound caused no problem, just irritating.

That's why I asked the question. Here's Duane's discussion of butterheads:

I am definitely concerned that I may have a butterhead problem. However, back in 2007 the previous owner sent the heads off to Memphis motor works and you can see by the invoice in the picture substantial work was done. Of course, that won’t keep the problem from reoccurring.

Re: R60/2 Question on rocker arm movement.
There’s no doubt that I have butterheads. I base this on all the work the previous owner had done on the heads 14 years ago and what is going on now. The issue is, what do I do about it? From what I’ve read nothing catastrophic is going to happen. The heads will just continue to deteriorate. My plan is to do a full rebuild on the engine over the winter. I’m somewhat reluctant to buy used LK heads off of eBay. Really no idea of what I’ll end up with. On the other hand, Bob‘s BMW is selling reproduction heads. Anybody on here have any experience with them? They still take short reach spark plugs. Here’s the link:
