Not only did they change the bolt to smaller for the 07+ (which I already knew), but I just noticed today that the bolts come with a blue lock patch on them from the MOCO. I'd a thunk that they would have a red lock patch on them, but that's just me.
I've also read that the bolt is too long or the washer is too thin. I know that mine will clatter when I pull off and don't get the rpms way up. The dealer has had to tighten it.
How ya know when the compensator nut is loose? I've got a chatter at 4000+ rpms and can't quite tell where it's at - other than on the left side of the engine. On the other hand, when the engine gets HOT, can rev above 4000+, seems to get to 5000+ before I hear the chatter.
Also wondering about the Feuling lifters I put in.
