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

[Sam Harris]

How does the inside of the valve cover look?

I don’t think I have a pic.. lemme see

Nothing big, just washed her today.

Does anyone know what this line is for? I thought it was a vent for the rear--it's not. Kind of above the spare tire.View attachment 373257View attachment 373258View attachment 373259View attachment 373260View attachment 373261

A drain for the rear ac?

I don't think that's it. Hose looks too small. I think a drain would be under all that stuff in the back towards the passenger side. I could be wrong tho. Thx Mark.

Emptied the catch can. On both chevys actually.

 

[MassHoe04]

I don't think it does. It looks like it's coming from above the rear diff--from the crossmember above the diff. I couldn't see very well, but I think it's tee's off of something up there. You can really see what I'm talking about in the last pic.

Did that rig have the load leveling or air suspension RPO codes on the glovebox sticker?
But, then again, the hose doesn't look like anything that would handle any kind of pressure.

Must be a vent or drain. That appears to be a factory clip attached to the chassis.
How far can you trace it back?

Nekked no more!
My Z71 has a proper roof rack now!!!

I was in a pinch when I bought my Tahoe. It ran so good and the interior was super clean, I had to jump on it. After I bought it, I realized it was missing the special Z71 roof rack with the canoe/kayak roller bar on the back. I was bummed about that, but determined that I would get one back on there someday. They are not cheap, so this was a long-term wish.

One of our good TYF members @06 Taco saw my post about wanting one and told me he had one available. He installed an Escalade rack on his Tahoe, so he could clear the garage door on his house. We worked out a deal, drove them from FL to CT for me (shipping was going to be cost prohibitive and a deal breaker for my budget) and he even helped install the Z71 rack on my Tahoe. What a guy!!! Thanks Jay! This is what the forum is all about!

I like that a PO de-badged (leaving only the Z71 plates). If you squint just right, you can't see the rotten rocker panels and looks half-way decent... Much better with a legitimate Z71 rack on her now!

I don't think it did. It was already pulled. I THINK he said it came from a Z71, but I'm not sure. I traced it as far as the crossmember above the spare. It looks like it goes into a "T", but since it's lowered I didn't have much room under it to move around--since I didn't jack it super high.

Any chance it is an EVAP vent tube that might have connected at the fuel pump or filler tube? Does it reach over to that area? Anything by the fuel tank look like it is missing a connection?

The guy who did it is gonna do the ball joint on my van this Friday--I'm gonna ask him. Hopefully he'll remember.

I installed the new coolant overflow tank that you guys pressured me into buying today and tidied up a bit under the hood. Now I can see the coolant level, what a bonus! The old one was pretty ugly for sure.

I can't believe you put that filthy hose and rusty hose clip on that beautiful overflow tank!

LOL - I know that you know I am just kidding in good-natured fun... Apologies, if it triggers the OCD too badly!

Love the rig! You ain't kidding calling it a rocket!

...pressured... I see what you did there.

New GM/ACDelco Combination Switch. I think PO put aftermarket one in. Was very stiff and would get hung up or down.

Your dash looks good/clean!

 

[S33k3r]

This is not true. Limited lifetime means as long as you own the car and no damage to the part that would come from incidents outside it's normal operating condition. Now nobody wants to just throw parts under warranty at a problem.

Also, just take it to a different Autozone when it craps out again.

Come on man you’re killin me! I cleaned the hoses up and used Silk Shine on all the rubber and plastic. I did not paint the clamps because I figured it would flake off when I opened them up to install ‘em. I actually bought 3 different sizes of expandable woven wrap as well as big enough heat shrink to install on the smaller hoses in order to look like braided line but discovered I couldn’t get it to look right where the tight bends are. I have only received one size of the wrap and no heat shrink due to shipping issues but I did slip that over the tube and taped one end to simulate the heat shrink and then tried pulling the other end to make it tighten up. I have used this on regular, non- formed hose that doesn’t have tight bends and it looks awesome. Not with this hose though, the sharp bends make it look terrible because there’s no way for it to be tight on the inside of the bends. I may revisit this with different hose that I’ll have to buy. So as you can see…I did try. I also swapped out the lousy ribbed plastic overflow hose that came with the tank with my rubber one.
Edit: OCD was in full swing, no prodding needed!

That vent line looks like the one that attaches to the carbon canister.

I wonder if you could put a small
Section of shrink over the top
Of the braid where it makes sharp bends, to hold it in the corners..?

The evap lines on these are hard plastic. It goes somewhere else.
