Blackarrow: Yeah, that sensor has gunk all around it. Was definitely going to replace that guy while the motor was torn apart.

RooK: I saw that one as well but I went with the one that contained the newer bolts b/c of the update that went out from GM. I figured if it had the new bolts, that it had the newer gaskets as well.

Now I'm not a design engineer, but on the surface it seems pretty stupid to have the pushrod guides built into the gasket. But that's just me.

Thanks to everyone for all the good info. I'll post an after-action report if anyone's interested. I've never tackled anything this serious by myself before. Wish me luck!

Thanks again everyone!
