Will try to blag a compression tester, but plugs seem a uniform colour so I'm
guessing compression is similar across all
4.

Rocker area is uniformly wet with oil, over all pressure is good.

Noise returns immediately on startup after the first adjustment, subjectively
worse when hot. Spot checking revealed no
change and all nuts still snug.

Well a couple are rounded now... ;) But still tighten fine.
Did you tighten the lock nuts enough when setting the

End float yes, up/down no, but then there's always a couple of springs pushing
up on it so I wouldn't feel any virtical
play even if it were there I'm thinking.

That last one.

No, likely not, however I'm thinking the problem could be the rocker arm shaft
and bushings, and since the springs will
have to be out maybe I should replace them for spacers at the same time....
Thanks for the links, I'll check em out.
