    14 tahoe 4x4 poor fuel mileage help

    I'm not sure what to tell you, but in my experience when you deviate from OEM as-built specs, you're bound to have a negative change in mpg (not all the time, but there is usually a trade off for more power, etc). I'm not sure what affect the VVT delete has on these motors. There are MANY...

    Best way to support engine

    Or, do one side at a time. Use the exhaust pipe to lift that side of the motor (gently) and they slide right out. 1 at a time keeps things lined up as well.

    2011 Escalade - worth repairing?

    With those miles, needed repairs (you mentioned front transfer case - did you mean front diffential?), rust, and wanting another 100k out of it I would personally sell it as is and look for a southern or western vehicle with less miles and no rust. The corrosion will slowly eat away at their...

    Dreaded Effing lifter tap...... - SOLVED

    I am in that boat now.......had it towed to a dealership due to an ongoing claim. It happened after the accident, while at the bodyshop, so it's an insurance thing now. I was at the dealership this morning for a loaner and #4 had a bent pushrod. Not sure HOW that even happens......never had a...

    Arlington plant closed temporarily - Open Now

    Moat definitely have the parts in hand. A slight of hand move to delay production because lots are full of 2024 models they can't sell for their absurd prices..... I've been to FL a lot over the years, and I can tell you there ISN'T a ton of manufacturers there supplying the big 3. It's...

    There are just some days I wish I didn't turn wrenches

    Welcome to the rust belt mechanic life! LOL GM uses some god awful loctite on the caliper mounting bolts for sure. It's blue and wicked......I never reapply any sort of loctite....ever, there's enough left on the threads for another 150k. A MAPP gass torch might have been enough if you...

    How many labor hours to replace struts

    What year and model. 2wd or 4wd?

    96 Tahoe 5.7 leaving me stumped.

    The first thing I'd look at is fuel pressure. The fact you were key cycling it 2 or 3 times which then degraded into giving it a shot of fuel to start leads me to believe you need to look there. 1. Check fuel pressure as stated by @strutaeng 2. Replace the fuel filter on the frame rail. Your...

    2021 MagRide blown strut

    This is all you need to know as @Joseph Garcia just stated. I concur 100%. I've done these style up front and they are cake to install. Having the proper spring compressor is key. I never had to reprogram any struts I put in. IF there aren't active codes present, I'd put on a pair and be...

    100,000 mile club

    Everything I own is currently knocking on the 200k door.......my 2017 is the furthest away at 160k. Keep up the good maintenance and you'll be able to easily turn that 1 into a 2 at the front there.....

    What is this bracket called.

    Be careful if you are going to attempt a repair. There's a lot of potential energy stored in those bars. I haven't personally replaced one, but I'm pretty sure you need to release all the torque on both bars to do any sort of service work that involves that cross member.

    2016/2017 Yukon Denali long term reliability

    Great info! I had a 2009 Denali just long enough to like the minute changes in the motor, but never ran it on true E85. I will say that my 2008 Denali LOVES E30 fuel (or equivalent blend of E85 and 87). You can feel the added torque when causing down the freeway. And, fuel economy is still...

    Dreaded Effing lifter tap...... - SOLVED

    The EPA is what drives this nonsense. Auto makers have to keep getting creative to increase power output because the engines have to run less efficiently to make "clean" air. It's a completely screwed up system. If engines were designed and tuned for "efficiency" you'd see many more diesel...

    Dreaded Effing lifter tap...... - SOLVED

    I forgot to mention I have HP Tuners. I used it to turn off the crummy AFM. My thought is to get my hands on a 2021 truck and copy the ECM files. Then, in theory I should be able to paste all that stuff into my tables and let er rip.......fingers crossed

    Good advice. I'll dive into it this weekend and see what transpires.

    Dreaded Effing lifter tap...... - SOLVED

    Agreed on all of the above. Equity is all mine, so nothing hanging around my neck in that regard. I'm hoping option 1 works ans I'll trade it off. If not, then a 6.6L is probably the best option and I'll run it until the wheels fall off.......

    Dreaded Effing lifter tap...... - SOLVED

    So, after 120k miles of no AFM, 160,370 on the clock I got a lifter noise. The truck was in the body shop for 1.5 weeks and probably got started and moved 10 ft a dozen times......go and pick it up and it's ticking. The guy says " we see that sometimes, probably just need to drive it." Man...

    Baffling Oil Leak

    Oil cooler adapter gasket possibly. Or, you have a rear main housing gasket that is compressed and leaking. The rear of the engine has a cover that holds the rear main seal, as well as provides a block off to the high pressure oil valleys in the block. The gasket material gets stiff, then weeps...

    2023 yukon denali 6.2..what to do

    I'm going to play devil's advocate and ask why you feel the need to do that on a new vehicle? OEM stuff usually lends rhe best driveability and longevity. It was tried, tested, and approved in a manner to get the most from it while delivering reliability. The only real way to improve on it...

    2023 yukon denali 6.2..what to do

    Depends what you are putting after them. If stock setup, then probably not too much change.

    What would you do? Truck Needs Engine?

    Then @Nel2son spend another $500 with HP tuners (or find someone who has it) and go in and toggle off the AFM in the fuel section. Super easy to do if you end up going a route like this.

    A couple of squirts of lube out of the boot.

    Does it have a rip that you can see? I've never had that issue other than a small rip causing it. If it's not ripped, the clampis still tight, then I'd say run it. But, if there's a way for water to get in, you're just running on borrowed time in the long run. Axles are cheap and easy to...

    2016/2017 Yukon Denali long term reliability

    I currently have a 2008 Denali as my DD with 192k on the clock and love it. My wife drives a 2017 Denali 6.2L, 8 speed with 160k on the clock. I can tell you that both have been great vehicles and shine each in their own way. The 2008 vintage you and I drive, are pretty bullet proof, easy to...
