What did you do to your NNBS GMT900 Tahoe/Yukon Today?

Nice! Check the rear coolant crossover gaskets too. Probably wouldn’t hurt to invest in a new VLOM while you have it apart but that’s up to you. And the oil pressure switch and screen too. Did you have any of the disintegrated foam under there?

What is a VLOM?

Interestingly the rear coolant crossover pipe isn't present in my 2012. Lol the only new VLOM I'm investing in will be one without AFM when I delete it. The foam was acutally intact, but the front piece wasn't in its place.

Lookin good. Are you gonna get everything done in time before you move?

Almost, my gearhead mechanic is completing the custom exhaust, running fuel lines, and external fuel pump.

Had an intake manifold leak to tackle today. Sounded like a choo choo train on a cold start when the engine idled down. Lot of caked on dirt and remnants of disintegrated wire loom under the manifold. Three of the ten vlom bolts were finger tight SMH.
Did an injection service yesterday in anticipation. At 150k miles, the upper part of the cylinder head ports still had some gunk on the walls, but you could see where the injector spray was hitting them. The valves were pretty clean as expected.

Im in the market for control arms. Never seen these adjustable ball joints. When would someone need these? Im at stock height on 22s with the autoride.

For someone who is lifted, lowered or was in a car accident.
