Valve Cover Torque Spec
Does anyone know the torque spec for the valve cover on my 300CD. I tried doing a search and couldn't find one, the only thing I came up with for torque specs is 9 Nm on a 190 2.3-16. I am guessing that it is probally somewhere around that on my 300CD, am I correct?

On the OM617 engines you can't really "over-tighten" the bolts as the valve cover itself sits on the head surface, however 8mm studs shouldn't be torqued more than 15ft lbs.
The factory spec is 15Nm & that is close to 10ft lbs. Have fun!
