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

[Tonyrodz]

So I do have to replace my knock sensors. I got some stuff to clean the intake ports and fuel injectors. Aso some red rtv I think I'm going to do the valley cover since I'll be there anyways.

But side note. What kind of OBD2 scan tools are you guys using? I was looking at this bluedriver scan tool which is bluetooth and $99 but iirc scans airbag and abs codes

Make sure to do that rtv mod. Protects the knock sensors from sitting in water.

Yup that's what the rtv is for

It is a very popular choice and seems to do quite well. It is a great option for someone who isn't wanting to go the tech2 / bidirectional route.

Tech2 is way too much

I dont need one it's just gonna be easier thn having to go to advanced all the time

I actually have two different ones. I bought one of the cheap obd scab tools and just a free app. It was ok. It would pull engine codes and could clear them but that was about it.

Amazon was having a sale on the BlueDriver for around $75 and I bought that one. It definitely has more options and pulls more. I was having issues with the rear heat not blowing hot air on my XL and it pulled error code for that. So I would watch the BlueDriver as I’ve seen it on sale a few times for about $75.

Thanks man. I want a scan tool bluedriver looks pretty good and has good reviews on videos on YouTube and Amazon I'll keep an eye out.

Ordered knock sensors, harness, throttle body gasket, intake manifold gasket, valley cover gasket and injector o-rings.

I also have some red rtv, got an inch-pound torque wrench and some fuel injector cleaner.

I found the torque specs for the intake manifold (44 in/lbs for the first pass then 89 for second) but was wondering if anyone had the specs for the valley cover? Also is the knock sensor "well" in the valley cover? Meaning if I remove the valley cover will it be easier to clean the holes the knock sensors are in?

Can you take a picture of the back of the headlights? I would like to see how the projector is mounted. I know anzo uses the same type of mounting points as stock. If these do as well k may pick up these lights and swap my retrofit into them

@Bombsquad85, Haynes says 18 ft-lbs, near the bottom of the page:

Retrofit by Lightwerkz in NJ this morning.







Had to hit the adjusters with PB Blaster and the drivers side still wouldn't raise the headlight enough. At this point it only clicks when you turn it but no adjustment. Headlights are aimed to low. I was able to wedge something between the grill and headlight assembly to get almost another 1" but I still feel like there is more room for improvement. Looking for a set of used Denali headlights. Hopefully I can get adjusters that will go up adjust enough. I have heard that the Morimoto H1 have a sharp drop off and I hope that's not the case here. See below for what I am talking about.





This is just before I wedged something between the headlight and grill.

Denali?

All black everything Should look quite sinister with the paint matched grill and hd hood .

You’re cut off looks like mine. Did you use mh1 7.0’s? I wish I would of done a little more research before I did my retrofit because the mh1’s aren’t very good for distance and they put a ton of foreground lighting, which is the opposite of what I need with all my leds and fogs.

Thats cool you had lightwekrz do the retrofit though! They are legends. I remember finding out about them in 2010, when retrofits were more underground and everyone was running ****** PnP hid kits.

He did use MH1 7.0. I have the same retro ut mine doesnt drop off like that.

I do have the same strange cutoff like his wall shot.

I really wish I went with a d2s projector... I think it would have been fine trimming some of the housing theres an awkward lip that looks like you could easily trim it to fit a larger projector
