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

[Sam Harris]

Started the Hoe to get some pizza and I get a loud tap coming from under the driver side valve cover.

Fuuuuuuuck

Are you sure an exhaust bolt didn’t just pop or header gasket blew a hole? It sounds very similar to lifter tick.

I will double check later today. That would be best case scenario.

Drove it yesterday. Picked up a 06 rcsb cheap last week. Will be pulling the 6.0 out of the Yukon to go in the truck eventually

Why?

Why?

A friend of mine has a bagged and bodied nbs rcsb. He’s having a full chassis built to help get the shop name out. I’m buying the rolling chassis. Swapping my 6.0 in it along with the body

Nice.

Here's my motor noise.

Any opinions welcomed.
Here's the condition of the header bolts.

I replaced that crappy little plastic connector for the heater hose at the firewall while on the side of the highway today... yeah, that kind of day

Pull the valve cover and inspect it, sounds like you have a bent push rod.

You really think so? I hope not.
