One of my valve covers is leaking and I am tearing it apart. I need to know what to torque the bolts down too. I am amazed how many bolts have to be remove to get the valve cover off. Can someone tell me what the torque specifications are so I can stop the leak.

If this is like your valve covers then 8 nm or 70 inch pound dont go over this torque setting or it will leak out again

That is not the same valve cover mine has the sparkplug wires goimg through it.

The 3.5 V6 M272 engine spec is 12 Nm first pass ,,,followed by another 90 degrees or quarter turn on the second pass.
Begin centrally working progressively to the outer and front and rear bolts.

Are you sure it is leaking from cylinder head cover? Most common leaks are from plastic back plugs or centrifuge cover.

Then perhaps you should include the model and year of your car rather than leaving everyone guessing.

Under the big T ,,,for Tim ,,it says 2006 E350.

The car is a 2006 E350 it does not leak bad but I hate seeing the engine compartment smoking when I come to stop open the hood after driving.

I would like to thank the two guess that posted the pictures they are going to be very helpful. I am fighting to find out where the last bolts are that are keeping the valve cover from coming off. I will post the results later today. Thank you

Thank you for all of the help, the pictures made a huge differance. The Benz is back together and now time will tell if I got the leak fixed. Again thank you.
