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

[Scottydoggs]

The flashing MIL was a random cylinder misfire code.

Been watching cam bearing videos, I guess my first step is buying a cherry picker.

flashing cel is like two things almost always, you needed a tune up like 6 months ago, or your cats are clogged up.

It has been throwing a catalyst code, for like 500 miles. I figured this was related to the low oil pressure, but maybe not.

low oil pressure should not be causing misfires or cat codes.

if its not knocking yet, op is not that low. most gm techs will tell you 6-7 psi at idle is acceptable. as long as it goes up when driving it.

then again, these trucks are known for the o ring going bad on the oil pump pick up tube to pump.

Already changed the o-ring, my oil pressure has crept down from 20 at idle to 0 the other night, died at the toll booth and was knocking afterwards. So it probably just needs cats and the engine rebuilt really. Eventually I will have replaced everything though I guess

damn that blows. back to that cherry picker plan. around here ive got rental places where i used to rent a hoist before buying one. used it a couple times and now it sits.

I have noticed my OP @ about 30 at idle and just over 45 psi when rolling. My rig over 260k but the pump and timing set were done before I took ownership of it about 3 years ago

I'm still around, just haven't been here for awhile. I still have my escalade, bought it 6 years ago with 105k, now she only has 128k. I did buy a set of springs for the rear, supposed to be 2" and ended up being 3". I also added the 2" shock extenders and the shortend level bars, I'll probably just add some 2" spindles this coming spring.

Got a dusting of snow this morning so I tested the AWD out in The Beast and my other beast, Kinjo. Both performed as designed I’m happy to report.

Mark...
Snow !! " It's getting to look lot like Christmas"....
I used to drive up to Tahoe..... Now I'm in sunny Florida..... " Not so much"..

Like my Mom used to say ( in Canada)..... " If you are cold,..... you are not dressed right".
