4. Tighten the valve cover bolts to 89 inch lbs. (10 Nm).
   
5. Connect the ignition wires from the spark plugs.
   
6. Connect all of the necessary vacuum lines.
   
7. Connect the CMP sensor connector
   
8. Connect the crankcase ventilation tube to the valve cover
   
9. Connect the breather tube from the valve cover

13. Connect the negative battery cable

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

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

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!

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

I hear you about the $$ situation - don't think there is anyone from that 1% group on these forums. But you're all set with the plan you have. If you see any oil in the wells, you can just give all the bolts another small tweek. And who knows, when you finally get around to checking the torque, it may turn out that your fingers actually did A-ok ;)

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

Thank you all for this thread. It turned the unknown into an afternoon's chore. One more point: keep track of firing order; the wires get pretty scrambled as they're pulled to the side.

Good Day could some one please assist me with this problems? My Aveo bend outlet valves when waterpump cranked up, i sent the car to be fixed, after a while the following issues arises

1) When i start(Cold Start in the morning) my aveo 2007 it smokes white smoke, soon as engin is hot it go's away

2) My car also leak oil through the head just above the plug closest to the battery side

the head was sent to an engineering works where they skimmed and reseat all the goodies

They say that the aveo 2007 does not get re torque is that true or must it be re torque?

if one new what i can doe or has a solution please assist you are also welcome to mail me direct on multi-master@vodamail.co.za
thanks
