    torque specs on valve cover

    my clymer manual lists the spec at 4.5 -7.0 ft/lbs. i hand-tightened first then set my torque wrench to 5 ft/lbs, criss-crossed side to side and front to back. i got a hairline crack beside the left-center-front bolt along with an oil leak. i will j-b weld tonite, but... tomorrow i will hand-tighten and only proceed to tighten further if there is any seepage. hopefully this will help someone from having the same problem.

    Valve Cover

    I had a problem with my Valve Cover too. When I tried to tighten them to spec. One bolt broke, and it leaked out the front. The Head and the cover were very clean and a new gasket. I finally used a thin coat of silicon gasket maker with the gasket, I don't have the stuff with me now or I would tell you what it's called. I guy at the shop said I should not have to use anything like that,but it worked. I never could tighten them to spec. Someone else on here can help you better than me. But that's what happened.

      A torque wrench that will read accurately at those low readings is VERY expensive.

      Use your hands and your brain.

      Also, on 16V engines it's easy to get the valve cover hung up on a dowel pin and crack it.

          If you really want to follow specs, you need to get a torque wrench that will do inch pounds, not foot pounds, and covert. They are in 1/4" drive, which should not be an issue.

            Yeah, not wanting to buy an expensive second torque wrench right now, anything under 10 I do by "feel"

              I just use a cheap one from HF, but keep a few weights in the gagarge in case I need to do a quick calibration check. For cover bolts, I also do it by feel. Cam and head bolts by torque spec.
