  1. Hey fellas, I purchased a 09 Yukon Denali. Had it for 160000 miles in Feb 2017. Good truck. However, I’ve been putting the wrong gas. Gave me a tick. Took it to a performance shop to get an opinion. He suggested a rebuild since the motor was detonated. I was game. I then asked about getting a little more power. He suggested a slightly bigger cam. I was game. I paid him. He swapped my motor and gave it back. The piston cracked and got stuck in the block damaging the heads and block . I took it to texon motors to get it evaluated and they suggested we call it junk. I was game. So now I am looking for a 6.2. L 9 H . My question is . Would I waste money buying a used motor and getting it rebuilt vs buying a Reman. I’m just looking for input to make a good decision before I get stuck again.
  2. John Goreham Contributing Writer, GM-Trucks.com 12-12-2018 Wards has named the General Motors 6.2-liter V8 engine with Dynamic Fuel Management (DFM) to its 2019 Wards 10 Best Engines Award list. “General Motors’ thundering 420-horsepower V-8 in the Silverado exemplifies how engineers continue to find ways to improve efficiency without giving up something in return. DFM determines 80 times per second exactly how many cylinders require fuel to meet power demands. And, incredibly, it uses as few as two cylinders to propel the full-size pickup down the highway,” says Wards' Senior Content Director Drew Winter. “The truly amazing part is the cylinder deactivation is imperceptible, so seamless that the only thing the driver notices is fewer stops at the pump." Coincidental to the award, GM-Trucks.com has just taken delivery of a long-term tester with this very engine. “Chevrolet first introduced its Active Fuel Management cylinder deactivation system in 2005, and Dynamic Fuel Management is a natural progression of the technology,” said Jordan Lee, Small Block chief engineer. “Dynamic Fuel Management enables only the cylinders needed to deliver the power you want, seamlessly delivering the best balance of power and fuel economy.” The full list of Wards' 10 best engines is as follows: 3.0L (B58) DOHC Turbocharged I-6 (BMW X5) 6.2L OHV V-8 with DFM (Chevrolet Silverado) 5.0L DOHC V-8 (Ford Mustang GT/Bullitt) 3.0L DOHC TurboDiesel V-6 (Ford F-150) 2.0L DOHC Atkinson i-VTEC 4-Cyl./HEV (Honda Accord Hybrid) 120-kW Fuel Cell/Electric Propulsion System (Hyundai Nexo) 150-kW Propulsion System (Hyundai Kona EV) 2.0L DOHC VC-Turbo 4-Cyl. (Infiniti QX50) 2.0L DOHC Atkinson 4-Cyl./HEV (Lexus UX 250h) 3.6L DOHC Pentastar eTorque V-6 (Ram 1500)
  3. Hello all, just picked up a 2011 Sierra Denali here and the truck is missing any type of manuals. I was wondering if someone on here could either provide me a link to an online version or copy me the 100,000 mile recommended maintenance? Thanks in advance!
  4. I have a 2018 Sierra 6.2 with Kooks headers, Kooks cats and K&N CAI. I've been thinking about installing a Whipple or a Procharger but I'm considering nitrous too. I'm looking at a Nitrous Express 20936 kit. I just want the extra occasionally and I'm concerned that the supercharger noise will be annoying. Anyone using nitrous on their similar truck?
  5. GMT-K2xx 2014-2018 Brand new in the box GM/Borla 6.2 exhaust. Part number on box shows dual side exhaust but laying it out it's a dual out the back exhaust, not what I wanted so its for sale.

  6. I just bought my 2019 Sierra Denali with the 6.2 and the 10 speed auto 😀 has good power just wondering about a tune especially which should wake this bad boy up if anyone has the new Silverado/Denali let me no what y’all think 🤷🏼‍♂️
  7. Seen alot of posts like this but none that quite answer my question. I have a 2018 Sierra 1500 Denali with the 6.2. I am thinking about installing an electric exhaust cut out before the muffler. (For arguments sake let's say my best friend is the warranty manager at my local dealership so I am not concerned about warranty mumbo) What I'd like to know is if I am going to run into any check engine light or any other messages popping up that she will pissed at me about it. I noticed alot of people with '14s and '15s not having issues with them but I feel like this 2018 has so many sensors and is so touchy that I'm hoping to hear from someone on here with the same year that has done it or knows of someone who has? I dont have any oxygen sensors back that far but is this engine computer smart enough to realize there is no backpressure from the muffler or something like that. I may just be being paranoid but really dont want to have to look at an idiot light over it. Wouldn't be worth it..or would it Any logical input would be very appreciated!
  8. I recently bought a new 2018 Silverado 1500 Crew Cab LTZ with the 6.2 liter & 8 speed transmission. I bought the truck in Idaho (great deal) and drove it home to California. Since then I've only put a few hundred more miles on it, 1181 total miles to be precise. Yesterday the tranny started shifting really hard & clunking on downshifts. Today, when I put the truck into drive it barely moves! Obviously, the transmission is slipping as the engine revs but the truck doesn't really move much! Any info on if the truck can still be returned at this point or am I stuck rebuilding a brand new tranny? Doesn't seem right to have to go through this so soon! I hope GM will either let me return the truck completely or give me a brand new transmission. Any insight on what may happen would be appreciated! Thanks in advance!
  9. Wondering if these engines will be tune-able as usual? Currently have my 2500hd LBZ, but am I'm looking to get back into a half ton for 2019. Ideally would like a 6.2 again.. Only concern is issues with tuning them like the new L5Ps uncrackable ECM. Want either Armageddon twin turbos or a supercharger with a mild cam down the road. If they're not, looks like I'll stick with my old truck.
  10. My 2014 Sierra 6.2 has 36k on it. Occasionally when I floor it going from the 1 to 2 shift and 2 to 3 it will make a backfiring noise and puffs a little dark smoke. Has anyone else heard of this issue or have any idea what would cause it? It's weird because it seems to come and go. It's stock tune with an airaid intake and gm Borla exhaust. I didn't notice it was doing it until I put the exhaust on. I've been considering a black bear tune and thinking that may help if it's a tune issue .
  11. Hey Guys, I have a 2010 Chevrolet Tahoe PPV with a 5.3L LMG and a 6L80 Trans (MYC) looking to drop in a 6.2L L9H. As far as I understand it is a direct swap. Would I run in to any issues or codes as far as the L9H not having AFM/DOD? I plan on using the 5.3L PCM and having it re flashed to work with the 6.2 Or do I look for a L94 that has FlexFuel, VVT, AFM like the LMG does?
  12. Hello everyone, I have a 2009 6.2 L9H planned for a project. Looking for info on what is needed, how to make a stand alone harness with the e38. Intended vehicle is a pro 2 truck with no luxury items needed. Mated to a th 400 manual valve body trans. Thanks much
  13. Okay so I bought a new Silverado last year, the day I took it home I installed a number of things, one of those things being a wix "coolant" filter Part #33032. GM actually has a perfect quick disconnect on the fan shroud so I just unclipped that and slid the filter into place. Why? I've just always been curious on a brand new truck. Does it actually matter? I don't think so because the trucks don't have a coolant fed oil cooler that could clog like the corvettes do so I actually might recommend it to those guys who do. What I found interesting was once I opened the filter there was a ton of gunk of a muddy type consistency. I've included a few pictures keep in mind the truck only had 7500 miles on it or so when I took this filter off. I don't see this playing a huge role in the lifetime of a vehicle (which is why GM probably doesn't include one) but I'm sure the gunk would clog small radiator/engine passages over time (years) of course.
  14. Hey Everyone, I am about to pull the trigger on a 2017 or 2018 Sierra 1500 SLT. My main issue right now is do I buy one on the lot with the standard V8 (5.3) or do I order one with the 6.2 L? I tow a 5000 lb travel trailer often and a smaller 10 foot utility trailer. I am coming from a Diesel Volkswagen Touareg with over 400 lb feet of torque. This will be my daily driver. I am not concerned about the money to upgrade the engine but more so whether It is worth it. I really like the power ratings of the 6.2 l but is it that much more noticeable than the 5.3? I don't want this truck to feel "slow" since I am coming from a torquey vehicle. Thank you

  16. 325 PayPal, or 275 PayPal gift shipped 2 day priority. Mails immediately . Around 10k on it. Never cleaned the filter as it’s not even dirty. But I’ll clean it and oil it before shipping as well.
  17. I was wondering if anyone has had a valve stem break on the L86 exhaust valve.
  18. I was wondering if anyone has had a plugged catalytic converter? the truck is currently in the dealers shop, The truck has 4000 km on it lost power and stalled on the side of the road no warning no cil before. The dealer is replacing the catalytic converter first they can't get it to run and GM will not let them do anything until they replace the catalytic converter. i don't know if the catalytic converter got melted down or plugged they had not cut it open yet.

  20. Oil Catch Can

    has anyone invested in an oil catch can? if so, what one and what kind of success??? Worth it?
  21. I have a 17 with a 6.2. It's left me stranded two times. 4800 miles. Problem is when I turn the key on I get stabilitrac failure/ power steering failure/ trailer brake failure/ low washer fluid(it's full). I have abs light, CEL, traction control light on. The screen goes to back up camera (in park). Also turn signals in mirror will stay illumanted. It'll start run for 30 secs and sputter and die. Then it'll just turn over. Wait for a tow truck and after the hour or 2 wait I'll get in to put it in N and everything goes back to normal besides CEL. Starts/ drives everything is back to normal. First vist pulled ecm codes and replaced the ecm. Got about 30 miles and 2 days and exact same problem again. Stranded until wrecker then cleared up and could start and drive. Any ideas? I'm nervous to take it anywhere. Only mods is MIT tube and catch can.
  22. I would like to know what superchargers are being used out of the three I am considering. Why you chose the one you have or which one you would buy being it Power output, Efficiency, Cost, customer support or any other benefits. Installation seems to be pretty easy with all of them, did you buy with or without tuner. Any thoughts, suggestions, info will be greatly appreciated 1. Magnacharger 2. Whipple 3. Edelbrock RT
  23. Finally took delivery today of my 2017 CCSB 6.2 max tow. Ordered it back late October and Chevy picked up the order Nov 3, Other than being a little slow it was uneventful until it was built and shipped. Trying to track it for more than a month I finally got a call from my buddy who is my salesman saying this was going to be the weirdest conversation he had ever had to have. He indicated GM had notified the dealership that there had been a partial train derailment and that my truck had made it to Michigan but was being held for a quality control inspection. I did a little Googling and did end up finding out the train was hit by a tornado in Thrall Tx and it derailed 12 autoracks . My salesman said their dealership had 3 vehicles that GM ended up buying back as they were damaged. I got lucky and mine had no issues. Couple shots of it at the dealer next to the 14 6.2 max to it replaced and one after I got back at my shop. Just got done installing the fold a cover and hope to swap out the factory rubber with some Cooper Zeons in the next few days
  24. Thinking about a new truck. Current is a 2014 LTZ Z71 5.3 with 3.08. I'll need to plow my personal driveway with this truck and one other short driveway. Anyone have a 6.2 that plows? I'm also looking at the 6.2 for some summer time fun with the added HP over the 5.3 and pushing snow. The 2500 is not an option for me. This truck will be a custom order and I would like some input before pulling the trigger. Thanks.
