So, I decided to do this replacement on my own on our '05 Aveo hatchback. Everything comes apart pretty smoothly- the oil around the spark plus tells me I should have done this awhile ago.
After trying to replace the cover for an hour with the gasket falling out, I went out and bought some RTV. Great! Gasket stays in place!
Snap a bolt using my torque wrench, the last bolt on the cover. ARGH!
Ok, I can handle this.
Take the cover back off, I'm able to remove the broken stud. RTV the heck out of that area, replace valve cover. Tightening bolts... snap the 6th one. Two snapped bolts- I don't think I'll be using my torque wrench anymore.
Autozone does not stock this part.
So, I laugh maniacally, come to the forum and find the part#. Looks like I'll be visiting the dealer's parts dept. tomorrow.
