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

They have fixed and portable remote emission sensors in various locations that measure the emissions as you drive by, and the results are collected along with your license plate number. Just another data point *they* store about us. Although in this case it can be a convenience (if the truck passes...).

haha, they didn't catch all those factory cheating Volkswagens though, lol
How effective is Opus remote sensing?-


Our programs have collected more than 150 million valid inspection records since the 1990s. We have identified over 3.5 million clean vehicles that earned exemptions from their next periodic emission inspection and notified over 30,000 high emitters of the need to return for re-inspection. We have also evaluated entire vehicle fleets and inspection programs and surveilled certified vehicle models to detect manufacturer defeat devices.

So true about the Krautmobiles. And I've never heard of anyone in Colorado getting a notice about excessive emissions -- maybe it's something we don't do here or maybe because my vehicles never failed (except for the gas cap test, and they make you come back with a new cap and re-test the thing).

Yeah I actually had my Civic pass by enough times I didn’t have to take it in for testing one year. Once.. lol. It’s cool when it works. There’s a portable station often setup on my route home from work. I drive by probably 15-20x a month.. funny thing though.. the guy sets up the green “sniffer” box, a couple cones, and then leaves.. not sure how well that can work when the truck that operates the equipment isn’t there! Probably leaves for an executive lunch and just says f-it..! [emoji23] I am very skeptical about the accuracy of these anyway.

Denver emissions is fun, especially when I had a wrx and they toss it on the awd dyno.

my diesel emissions is/was a pain in the ass. Thankfully I now have collector plates so only need it every 5 years.

Drove it hard and fast, then put 23 gallons ($69.00 ) of Chevron 93 Octane in it.

Does anybody have little specs of ‘glitter’ in their catch can? This is the first real oil change on this engine so I’m not too worried but I may dump the contents of the can into an oil sample container and then take a sample of engine oil and send both off to Blackstone for oil analysis.

edit: I should also say that the can is only up to this level in the can after a few thousand miles

If the particles are so fine that they can remain suspended in the oil vapor of the PCV system, then I wouldn't be too concerned with it being from a new engine. I'd still have it analyzed because that can help narrow it down to bearing coating or iron (oil pump rotor, valvetrain, etc.), just so you'd know the source. At this point, I'd bet that it's just parts breaking in.

Replaced the rear passenger window switches.

I found this on eBay @Rocket Man . Figured you may be interested in it. I’m trying to find one for my GMT900

My GM rubber floor mats arrived! They feel super high quality and I have to say I’m very impressed. I will be throwing them in tomorrow!
