tightening torque for valve cover?

I would say its not that critical. You can always follow the same sequence as with the head and the torque would be like 20Nm.

Greetings Niels

The recommendation is to start at the center and work out.

The setting isn't critical, just replace the gasket and work your way out from the middle with a ratchet wrench. More than a few guys have gotten themselves in trouble by misreading the foot inch reading used for many valve covers as foot pounds and setting a torque wrench accordingly.

_____ No, 20 Nm looks too high! The nuts are probably a 6 mm metric thread size. If yes, then torque should be about 108 inch-pounds = 12 newton-meters (Source page 24-2 Haynes VOLVO 240 Series, ISBN 1 56392

136 7). A torque of 10 Nm corresponds to the recommended maximum torque of a M6 8.8 grade bolt/nut. Info about bolt torque can be found on the internet or in any decent Mechanical Engineering Handbook.

many thanks to all
