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

[blueinkd]

Good luck... I guess before you first start the engine, you let it crank first without fuel pump relais, to make sure that oil is everywhere where it should be?

Got her fired up last night. Won't stay idling unless I hold the gas or disconnect the throttle body. Going to driver her to get driveability tune this morning. Sounded good, no leaks or weird noises. Valve train seem a bit louder, is that normal with the cam and spring kit???

Sitting at the tuner now. I went with Elvis Custom Tuning here in Houston. Had gotten several good references about them.

Today I replaced my front rotors and pads, and while I was at it I upgraded the OEM torx head caliper pin bolts.

Making progress on the rocker panel job. Should be ready for the road this coming week. Got some rust proofing done today, interior trim pieces put back in, and doors and wheels put back on. The body guy is going to get it painted this coming week now.

Found something interesting though as I was putting the interior back together. The trim piece that goes in the front corner of the passenger foot area had some black stuff that wouldn't wipe off as I was cleaning things. When I went to put it in I found that the shield at the blower motor had a hole melted in it. The wire connections are all made with wire nuts (which I'm confident is wrong). The blower motor housing looked to have a spot of melted plastic too. So not sure yet what I stumbled onto and if there's anything wrong or it's already been "fixed".

Changed out the blower motor resistor

Replaced brake hoses and changed the transfer case fluid. I dodged a bullet with draining the transfer case as it was way overfilled. More than a quart of extra fluid drained from the fill plug. It may just be me but I think the rig drives so much better and smoother after all the refreshes.

Did you overfill it? If you did not the transmission oil maybe leaking into the transfer case. Please check the level of the tranny oil.

 

[Gmg0547]

This is my first time changing it. I checked the transmission fluid after changing to see if it dropped at all but it still looks good. I'll continue checking this to make sure it's not dropping.

Less than 500 miles on the new motor and tune and some sack of garbage decides to side swipe me. No insurance or driver license either. Already filed claim and looking at a 250 deductible=/. Not bad but Damm there goes my oem fender!!

I hope you shoot him, before he can damage other GMT 800?

Picked up a rust free Z71 body with good interior. Just gotta find the time to swap it.

No need ammo to expensive!! Hahaha!! I'm over it I got the claim in and should be taking it to the collision shop before end of week. It's and old truck, I know it but I don't spent money of full coverage for no reason!! Probably go get my alignment checked at firestone this morning since I got on the curb to keep from taking more damamge and luckily my wheels were not damaged!

I'd add that to your insurance claim

Today I changed the o-ring of my oil pump.

Therefore and to clean the engine as well I drove to the fuel station open my hood and tanked one liter diesel in my engine, drove half an hour and then flushed the oil.

The people at the fuel station really looked at me with a strange look.

After that I disassembled my oil pan and changed the O-ring.

How big of a job is this?

Not a big problem if you have a lift and a little bit experience. I think I need about two hours.

You must drain the oil.
Then disassemble the steel bar under the oil pan with 4 screws.
Then lose 4 screws at the differential to lower that, to have enough space to remove the oil pan.
Then remove all oil pan screws.
Then remove the oil pan
Then on the oil tube there are 2 nuts and one screw you have to remove.
Then you can take the oil tube out, remove the o- ring and everything return.
The oil pan gasket was attached to my oil pan with two rivets. I think this is still from production. I had to drill out these two rivets.
You should also use sealant on the corners of the new oil pan gasket because the front and rear covers of the engine come together and the oil pan can leak there. and you should urgently tighten the oil pan bolts with torque.
When inserting, I attached the oil pan gasket to two screw holes with two cable ties so that it stays in position, which I then cut off again before screwing it tight.

All in all two hours of work, no big problem and afterwards a good feeling, because this o-ring was in my stomach the whole time. If it fails and you don't pay attention to the oil pressure, you have an engine problem.

And by the way.
You need the O-ring, a oil pan gasket, some liquid sealing, the gasket of the oil lines to the oil cooler at the oil pan.
And additionally an oil filter and oil

Yeah the other thing on the Denali is the oil cooler line hold down bracket. You need to remove it and their is a certain sequence. I don't quite remember what but I remember having an issue where I had to put things back together in order to remove something. Also the long skinny bolts have a low torque value in inch pounds they are easy to strip out if you are not careful.

Do you mean the hold down bracket of the transmission oil cooler line? That is only mounted with the small screw you can remove and afterward tighten it again. It is a little bit narrow to work there, but possible.
Yes I had no torque for the two long screws, but due to experience my magic hands are like a torque wrench...

No the engine cooler lines hold down, it's right near one of the front axle bolts
