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

[Doubeleive]

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

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

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.

There is, I replaced mine on the 02 and I hardly get anything in the catchcan now.

Gen3, Gen4... it's all pink insi- I mean, they're all the same under the valve cover.

Is it for the pcv nipple/deal? I remember that being different between my 2.

That did change a time or two or three throughout the years. But, this wouldn't matter if you had a catch can like you should cuz you'd just slip the hose over the nipple and secure it with a hose clamp.

Finally new headliner, went with the new car style knit. Almost forgot, here’s my old pickup oring. Kind of cylindrical instead of donut shaped, didn’t have low pressure before, but it did raise 7-8 psi

Yup.

Drove around the other day, watched a guy in a Maserati bury his car in a foot of slush. So funny. I wouldn’t even drive my Denali through that. That’s him, probably on that phone when he did it. View attachment 271181View attachment 271182

The skinny jeans tells me that he makes great decisions in life

I decided to make an instrument cluster repair harness. Rather crude, but does the job.
