Hi, the 15 nuts that lock the valve cover in 16v redblock they have a specific tightening torque and sequence or goes to hand? thanks
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.

_____ 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.
