would this be the same for a 2007 aveo and what sequence do i use like start in the middle and work out?

Yes it is the same.

[klunk]

Yes it is the same.

thanks for that reply i did not have a inch /lbs torque wrench i was told to finger tighten bolts then rachetb tighten another 90 degrees which i did i see no leaks although i dont like doing that you really dont know how tight the bolts are i will get the inch / lb torque wrench and do it right

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!

thanks for your response i ended up finger tight then another ninety degrees it was a sunday and could not locate the inch torque wrench

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.

hello I have a new problem was wondering if you could help I have a clunking noise in the dash passenger side near the window or about that area how do I get the dash off on the right side to see what is rattling when I hit bumps in the road it sounds like a clunking noise I looked up under the glove box but could not feel anything loose

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