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

Changed the valve cover gaskets... hoping that fixes the oil leak...

How difficult was this to do?

Isn’t there some minor design flaw with these GM engines that causes them to slowly burn oil off? I seem to remember reading something a while back about the placement of a valve or port or something causing it.

Halloween around 1987. I'm driving down the road and two kids throw eggs at my car and I quickly pull over and wash it off at a nearby gas station. Just then my buddy pulls up and we go down the street they ran and catch up with them. They see us coming and start running, my buddy passes me, they run into their house and into their bedroom. The windows are open, my buddy pulls right up onto their lawn, jumps out and showers them with BBs from his new automatic bb-gun! Bet they never did that again! We skedaddled after that right quick before their parents realized what happened and came after us!

The PCV systems are known to cause oil consumption. A lot of people use something called a catch can to catch the oil before it enters the intake. There’s a lot of info on them here.

Can’t read it. Zoomed, it just looks fuzzy.

How long did it take you? I need to do the same to my Yukon Denali.

Grab him, put an egg in his mouth, then smash it! Bet he'd never do that again.

Or shove it up his ass.

Upgraded to 22" replicas. Before, during and after pics below along with story...but I do have a question for anyone running 285/45/22 on this body style...what PSI do you have? I put them at 35

So with my state inspection coming up in September I knew I'd need new tires, and two of my TPMS sensors were bad as well. So I was figuring over $700 for 4 with 2 new sensors and mounting/balancing. Looked on LetGo and found these 22" chrome replicas with pretty decent tires for $500. Some light scratches and one of the tires has been plugged but I'm calling this a deal considering I had to get new tires and what I was able to get for less.

Now I need to figure out what to do with my OEM 20"s. They're not in the best shape, NY Winters have not been kind, any idea if they even have a value since they're OEM?
