Well I replaced the rocker with the $22 part from ebay

and the $60 part from amazon to compress the spring. (really well made part FYI)

And this rocker came off easily....almost too easy thought I broke something!

Shows a little wear, haha. I can see how the tick happened with that much clearance.

I took some 200 then 400, 800 and 1500 grit and smoothed out the cam.

The whole problem started due to a blocked oil drain tube above that cam so it wasnt getting oil at idle. Also got those replaced for $10 for both sides and simple fix, just the parts have to be broken off to replace them.

I was almost hoping the thing would tick so I could be done with it and just part it out.

SURPRISE, no tick at all??

I am thinking of changing all these out on my 560SL after how easy it was and I have the tool.

I will change the oil since all kinds of junk got in around the valve covers.

Easy fix for a car with 170k mile that has many other issues....

Thanks for all the advice and help!
