      Sequence doesn't matter for the valve cover bolts, only the head bolts.

      Yep - 89 inch pounds is the spec we found when replacing the VC gasket on my 2007 Aveo. We couldn't find a sequence (nice to know it doesn't matter, Daox) but we started in the middle and worked out, alternating L/R). It's been over two weeks now and no more leaks!

      I think if someone spends all day turning wrenches, and does the same jobs repeatedly, they can probably get very good at "estimating" torques. Being an amature DIY mechanic, I don't have any confidence in my ability to torque accurately by hand. The extra length of the torque wrench creates different leverage, and this can cause a shorter handled wrench to be apples-to-oranges (to me anyway). Although I've done other similar gaskets having just about the same torque spec, I'm always a bit surprised how these rubber gaskets seem to settle in, as the bolts get turned down. I end up making more turns than I originally would have expected, in order to get to the specified torque. So, that being said, finger-tight + 90 degrees SOUNDS like not enough to me. But who knows - maybe your fingers are a lot stronger than mine are . Bottom line is a loose gasket would cause leaks, and your spark plugs wells to get filled up with oil, so you might want to consider buying the inch wrench and checking the torque, in order to make sure this doesn't occur.

      yes absolutly correct i do plan on getting a inch torque wrench i used to work for a gal doing hvac and i borrowed hers for a day when i was rebuilding my harley the clutch plates needed to be torqued to a inch lb torque it worked perfectly its just right now money is tight i have gone back and checked the wells where the spark plugs are and no oil so what i did is ok for now and i will be rechecking perioudically until i get that wrench and set it then i know its right
