I am chasing a ticking sound in the right bank of my E320 4 matic (M112 E32 engine).
I have removed the covers and I noticed a side-to-side play in most of the rockers.
Apparently this is normal (?). How much play would be too much?
Could this play be the cause of the ticking sound?

(The ticking sound I am hearing is very light and I suspected the lifters. Seems a normal thing for these engines)

Thanks!

No, it's more likely the hydraulic lifters.

Thanks!
I am still wondering how much sideways play would be acceptable.
