Valve adjustment OM615, 616, 617 FYI.

[whunter]

Needed every 15000 miles.

FYI: for new members.

It is important, especially for winter starting!!!

If you DIY, do NOT mix up intake and exhaust valve positions while adjusting.
A hand drawn check box diagram to document each valve, intake and exhaust position, will save much confusion and effort.

The feeler gauge goes between the cam shaft and rocker arm, graphic drawing in post #22...

You will find the MB valve wrench set handy, or you can make your own...

Here is a nice DIY with pictures, but I disagree about using an offset key, IMO you are better served by rolling in a new timing chain.
