What did you do to your NBS GMT800 Tahoe/Yukon Today?

may as well ask now while I am waiting for the covers to ship, what is the torque spec for the valve covers?

Haynes says 106 IN-lbs in three or four steps for the V8.

ya not sure if it has the updated cover or not and don't really feel like cleaning it and I don't have a parts washer and she drives it everyday, easier to just buy the latest one and be done with it. I have a catch can I can put on it also if need be.

I didn't know there's an updated vc for the nbs.

I'd be curious to know if the new VC is different from your old one. If you think of it post up some pics of the inside of both VCs when you do the swap.

I know what it should look like inside if it has the updated one I just don't know if it has it or not yet, if it does and it's not nasty looking then I can just return the one I bought. either way I will post up some pics in the process.

ya that inch pounds has got me before lol when I did the knock sensors, I was like hmm this seems a little tighter than what it "snap" should be

the pictures I saw online showed 3 different versions, one with like 3 round holes and with small rectangular holes in the baffle, and the latest one with basically no holes and just a small pin hole on the opposing end from the pvc.
