Gen 1 cam cover seal

[PL2112]

Anyone else that does their own servicing use sealant on the cam cover gasket?
I recently done the 18000 mile service and the seal ring seemed fairly well stuck to the cylinder head so I left well alone. Unfortunately I had a small leak from the half moons on the LH side so have had to pull it off again. The seal was partially stuck with what looks like 3 Bond. Would it have come from the factory like this?
I've done plenty of bikes with this type of seal and usually they don't need any sealant.
Interested in what others have come across?

Yes, I've never opened one up myself but from everything I read and seen, it's a silicone RTV sealant https://www.s1000rrforum.com/threads/timing-cover-gasket-help.171353/. On my bike, there's a thin gasket next to the sealant after my old dealer opened it up. I think they cut a paper gasket instead of resealing it with sealant. I've had no leaks.

The thread you linked to refers to the cam chain cover on the right hand side of the bike. I'm asking about the valve cover on the top of the cylinder head.

When I did my 30k km service the rubber gasket was as you say, stuck to the head...I removed the gasket and cleaned all sealing surfaces as best I could and then did indeed use the Honda specified "Three-Bond" sealant on the gasket and half moons. I believe BMW use a similar sealant. Just be aware there are tiny little rubber tabs all along the rubber gasket and it's possible to "miss fit" them unknowingly, especially at the front, if one or more are not positioned correctly, it will leak. be sure to check all are in the correct spot.

Here's an example, (below), of the little rubber tabs on the rocker gasket on my bike. Hope it helps.

Same, cleaned it all up, thin layer of sealant, job done as always.
