make a super long story short, just by taking the valve cover off can you see a broken spring or do you have to take the rocker assembly off? its a 04 C15 MBN thanks

yes....

yes the rocker assembly has to be removed? aparently i have a broken valve spring on the same cyl i just did the injector in. there was a tick in the motor.. they said it was the valves out of adjustment. they test drove it the tick came back. turns out they removed the rocker assembly and they found a broken valve spring. same cyl the injector was done.

Sorry...my bad......Yeah...remove the rocker assembly to check the springs.


Did they charge you for the broken spring? It should have been on them....IF they had done the injector.

lucky enough for me it was under warrantee..
