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

Well good afternoon gents, its been awhile!

You had better have one hell of an update on that build after deserting us for so long.

Literally the only issue of noticed, besides the elevated oil consumption, is that either exhaust leak or valve train noise, and the exhaust leak is completely unrelated if that's what it is, and the valve pick, has slowly been getting worse over time and didn't happen until maybe 6 months after it overheated when I noticed, so likely also unrelated.

I'll probably just measure the bore both directions down every cylinder in the top middle and bottom just to check for uniformity and make sure that's not an issue, just trying to save down time when I rip it all apart.

Set aside a whole day for it, and it's boringly monotonous work, but I'd strongly recommend a thorough compression test before you tear it down. Closely document everything you find. Pouring a little oil into each cylinder and testing again would differentiate between rings and/or bore and valve sealing issues. Measuring after you have it torn apart would tell you how much, if any machining you should do.

yeah, i def want to to comp and leakdown before i tear it down.
pretty sure i have pics of previous numbers...cant tell what cyls from pics though.

Another news, ran to home Depot with it to pick up some bug killer because my house plans have a ton of gnats all of the sudden. Ended up picking up lavender plant in the meantime since actually have some right now. Had to put it on the passenger side floor mat because I have so much crap in the backseat and cargo area... I really needed a garage about 10 years ago.

What up?

Finally swapped the white DRL bulbs back out of the turn signals and swapped in amber led bulbs in. Also changed the cabin filter. Wasn't too bad actually.

And I guess I didn't test it thoroughly enough yesterday when I was installing them. But I definitely have hyper flash now even though the tail lights are still the original bulbs.

you will need resistors or bulbs with resistors built in, the only seller I have seen with resistors built into the bulbs that actually worked is auxito
you have to get them from this guy though because others are fakes or not work

changed out the right side fan motor that was questionable, burnt the connector and one pin was obviously getting hot, motor was about 4-5 years old
