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

[Bigkevschopshop]

A 2012 Escalade with 46K and 6.2 sounds very enticing. That being said, I would keep the LT Suburban and the lack of payment. At 123K, it’s just getting broken in. Out what you’d put towards a payment away and after a while you can step up a few more model years or have enough not to have a payment on the next one.

Yeah... after some soul searching... You guys hit the points that were in my head like a roofer hitting nails... 6.2 would be nice... but I got what I ultimately have wanted for the last 12 years since the 07 came out... Like the Tahoe-burb front end better anyways... Hell I could just 6.2 swap this old gal if the AFM eats itself and have the mail hauling machine I want. I have done all fluids except the coolant, was going to do that probably a water pump and thermostat when it gets cooler out just as preventive.

You guys are some of the reasons I like this place so much... Feel at home!

Guess I need to work on ditching this superchips tune and go ahead and do the BB.... Thinking a 2/4 may come before the end of year.... Spend some money on fun for once...

Thanks for all those who chimed on with good voices of reason... I know she is getting broken in... Actually rides better than that mag ride for sure.....

This guy is sitting on a 30 hp boost theoretically..... Impressive....

Anyone want to guess on the make of this picture? The problem is circled......haha

I don't see anything circled--unless I'm missing it. Looks to be a ford tho.

I kicked myself in the rear for years for not getting a 6.2, lol after some years of improvements on them I got one and the mileage I get works out to about the same as what I was getting on the 5.3 years ago about 10mpg, currently it's sitting at 8mpg though I can only assume from so many short trips around town.

Hmmm, new mod I must’ve missed... will have to try soon...ive done the vise grips under motorcycle trailer for a 3000 mile road trip then 2 years until i went under to fix something and found them mod...

Yea was more of an impulse mod after the wife slammed the door shut and then a thud of the window falling down. New regulator will be here Wednesday and the vise grip mod seems to be holding up just fine.

That’s how my caprice looked over the weekend. Most annoying part is the grounds on the back of the heads (don’t know if the hoes are the same, haven’t done mine yet).

I ordered a set of Akebono brake pads from rockauto.com. They were only $2.00 cheaper than Amazon after adding shipping then applying the forum discount, but $20 -$50 cheaper than other online vendors for the same model numbers. Also good to use a supporting vendor.

I've had good results with Akebono pads on other vehicles, and others have posted positive results in this forum, so I am sure they will work just fine. I went with the ProAct Part numbers ACT1363 and ACT1194A. I didn't go with the Performance because I don't tow or haul often.

I can't believe your heater core T-connectors are still in one piece. Might want to attack those while you are this far into it.

Been there! Done that! Mine was #5 Intake lifter on my 2007 6.2L. Roller locked up and scrubbed the cam. Got to it before it made it through the hard candy shell into the soft nougat center. Motor had 120K on it.

Ever notice the oval around the ford script. They circled their problem.

Finished up a nice labor day NC to DC round trip, averaged 17.5(18.9 on the way up) anyway it's not about the MPG.. but it's nice to know it's not 13.

Need rear brakes next, that's for this weekend, I imagine I can make the rest of the week of commute(8miles) on the backing plate

I think you should be able to muster better than that, unless there is a lot of idling

And Chevrolet dressed theirs up with a bow tie.

This reminds me of the words spoken by Nasser Abo Abdo, the former president of Audiobahn: "You can't polish a turd, but you can always chrome it!"

Dropped the heads off at the machine shop at 10:30 and picked them up at 1:30. Only $120 to cut them and hot tank

Actually, years ago Mythbusters did prove you can polish a turd

it was on 10 for a long time then I reset it 3-4 months ago and now it just sits on 8, i'm going to pick up one of those infra red thermometers and check my cat temp's. I have a heavy foot but not driving any harder than I was a few months ago, truck runs great, just thirsty lol

Would a failed VVT solenoid actuator cause this? I can’t recall right now which way the cam defaults too, but just a thought.

no idea but no codes and I've checked everything basically, fuel trims are good, fuel pressure is good, no misfires, no leaks, nothing has changed but the mpg
