WOW absolutely great shots! Unfortunately I just cannot find marks like those anywhere on my cam plates.

I have these two "Tools" and neither one helps locate any marks like the ones you pictured. I am currently attempting to determine whether I have a M276.8 or M276.9 Engine. I believe it is a .9 but the service rep from MB should be calling me back with the specific number. Once I know which tool to use, I'll attempt to align the cams with it.

I searched with both tools on both backing plates on the cams and cannot see any marks like the ones you show. I sure wish they were visible.

I will check again after the sun goes down a bit to eliminate some glare.

I understand that WIS AR05.20-P-6010GQ shows positioning of cams at 53 degree timing mark, with the valve cover mounted. I am going to try that.
