Hi all, some more clacking/ticking here.
(I'm sorry Rick, I don't have a solution yet)
Since a few years my V2K also started ticking in the top end of both cylinders, and I'm fairly convinced it's the HLA's. So I opened it up. Everything looks OK, but there's one thing that I don't understand.
As the HLA's rely on oil pressure for their operation, I checked for clogged up oil passages etc. It turns out that all oil flowing into the top end is forced through a filter built into one end of a rocker shaft. I've never seen this type of oil filter/screen before. It's made up of tiny brass balls, pressed/fused together, so the oil is supposed to flow through between them.
Then I found this:

Now if I try to blow through the screen, I can only manage to blow a tiny stream of air through, even though I'm blowing so hard my face turns purple.
But the strange thing is, after the oil flows through the screen, there's lots of holes where the oil flows out to lubricate some part. It even goes through the pushrods!
My point is, if there's so little flow through the screen, but there's so many ways for the oil to go once it passes the screen, how will there be enough pressure for the HLA's?
Or is my oil screen clogged up real badly?? It doesn't look dirty at all though.
