Hi,

I broke a timing chanina and bent the valves in this engine. I have the engine repaired and i am putting it back together, but I have a fundamental question on the valve adjustment on these engines. The pivot appears to be hydraulic with a pretty sizable amount of adjustment, how important is the valve adjustment on this engine? Does anyone have any advice or cautionary notes on adjusting the valve clearance? Also, do I have to have the Mercedes valve adjusting wrench to complete this job?

Any help would be greatly appreciated.

Thanks,
Ben
