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

[Tonyrodz]

So, you can't pull the pan, to access the pump?

I was told it was probably too late. I actually have another motor, I just have to buy the usual--knock sensors, gaskets etc. I think I just rather do that instead of paying to replace the oil pump and related gaskets, only to find out it didn't work. For a motor swap, my buddy charges $500 just for labor. That's including getting it to run. I know to do the oil pump would be at least $400 just for labor--since I can't do it myself.

Seems like what I did for my old '88 GMC truck..... At 220,000 miles, I needed a valve job ( valve seals were bad)...... My mechanic told me to get a 350 cid, 4-bolt main for the same price.
That engine was fire breathing all the way 'till I sold it with 392,000 on the clock.

That’s low mileage. Barely broke in.

Not bad at all. It's worth more to me as a running vehicle that what I would get on trade or selling it. So its gonna hang around and be used seldom

Sure....No problem..... It is attached to a 1970 Chevelle. ( The engine is fire breath'n )

Well I have about 7 codes showing up including 3 codes for Bank 1 Sensor 1 O2 sensor, MAF sensor and Knocj sensors (again) . Trucks running like a pig and I'm getting shit gas mileage. Bit the bullet and got a new 02 sensor, maf and know sensors and harness again

Me, being from west Canada, and lived in Kalifornia,.... I learned to VISIT the snow..... only visited Big Bear Lake, Lake Tahoe & Frisco, Colorado......then got the hell outta there!

But, that photo shows a nice contrast to your Tahoe.

im good with 2 or 3 month winter. But I don’t even want that anymore. I’m sooo over it

So parts came in earlier than expected. Bank 1 sensor 1 O2 sensor was a ***** it get in. Had to have my wife help because my arm was too big to fit between the exhaust and driveshaft.

MAF was a breeze.

Got the new knock sensors in. Built the dam higher this time. Also found out that I had a pretty big oil leak from the oil pressure sensor so I cleaned and tightened that. Turns out that my socket didnt fit fully around the sensor without removing the valley pan bolt closest to it...

Removed the valve covers and thoroughly cleaned them. Tomorrow the harness for the knock sensor will be here and I'll put it all back together. Hopefully no CEL this time.

I was gonna paint the valve covers but decided against it.

I'd just scrub the vcs clean with some degreaser.

That's what I ended up doing. I used a bristle brush with some simple green. Once the majority of the grease was off i used some long tipped cotton swaps for the grooves and tough to reach spots and a wire brush for the stubborn parts. They arent perfect but they look 100x better. Maybe some day I'll pull the motor and give it a solid clean up... inside and out
