tightening torque for valve cover?

Discussion in 'General Motoring' started by Telespalla Bob, Jul 22, 2007.

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

  2. Hi, the 15 nuts that lock the valve cover in 16v redblock they have a
    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

    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.
