Ark, I took my first ride in the HHR about a week after you posted pics of your cams and head, I could hear that chain big time. You're the reason I took it apart.
Do you know the torque spec for the new bolt?You narrowly avoided the fate of my first donor's engine. It was painful to see rockers broken off and laying all over the place in the engine. I'm happy yours survived.
Anyone reading this that has not done it, install a new-style tensioner and a Dorman bolt.
66 ft/lbsDo you know the torque spec for the new bolt?
I agree with Ark 66ft/lb is a lot for a 6 or 8mm bolt. I mean if it stays in one piece it will definitely be tight though66 ft/lbs
After seeing how this bolt is made. It is 55 ft/lb. for the bolt. Dorman Instructions The original 6mm bolt was only 89in/lb. since this is using the threads for the plug it is a lot higher.Hmmm.....according to Chilton DIY the original timing chain guide bolt for my '10 SS/TC should be torqued to 55 lb ft.

That video says to tighten it "according to the factory specifications for the access plug."After seeing how this bolt is made. It is 55 ft/lb. for the bolt. Dorman Instructions The original 6mm bolt was only 89in/lb. since this is using the threads for the plug it is a lot higher.
Sorry Torch you were closer than I thought. But I still say at 55 lbs it will be tight
What is crazy is I have Alldata full version not the DIY one my specs are different. I looked up a 2005 2.0 SC and my 2009 2.2 NA and both say 55 lb/ft. ??????Thanks for the hep everyone.
I got the 66ft-lb number from the Cloyes video on Youtube. That is the torque spec for the plug that RouteAbel pointed out. Interestingly enough, when I got to a desktop last night I checked alldata (duh, I dont know why I didn't think of it earlier. Guess because I've never had it before), and their number matches Cloyes. The interesting thing is that its different than the cobalt ss/tc and HHR ss/tcView attachment 10935
Anyway, thanks for the help.
That is weird. On a seperate note, is it really possible to get 22ft-lb and another 100 degrees? We got about 80 and things are making wierd popping noises.What is crazy is I have Alldata full version not the DIY one my specs are different. I looked up a 2005 2.0 SC and my 2009 2.2 NA and both say 55 lb/ft. ??????
