Seems like 6.2's going out around 19k is the trend these days. Mine went too buddy! New engine should be in this week hopefully. Thank god I didn't put an evil air intake on the truck yet or I probably would've had to deal with the same amount of BS you did. Good thing your trucks up and running.

I just want to add to all of this: From day one, as soon as the CAI was mentioned I got on the phone with K&N and they were 100% with me through the whole ordeal. They flat out said, if they pro

So here is an update since I have not been here in months. The engine failed due to a valve spring breaking and the retaining clip also failing allowing the valve to drop into the cylinder, the pist

There's two things that hold me back from doing it. First is obviously the financial side. The other is the High Country interior. A lot of people don't like the brown interior, but I absolutely love

First Ive heard of a 6.2 breaking, that engine is a beast!! The 2017 Aluminum truck's 6.2 is supposed to gain 25hp and get much better gas mileage, Iam already saving my money for one lol I also hear the 5.3 will be up to 390 hp and a possible Supercharger option. None of this is certain but we all know its coming soon, aluminum that is.. Next Fall could be interesting

Don't worry at least at 19 they're still under warranty. Unless you're tuned or something.

Thinking about trading in my High Country 5.3 for a Denali 6.2. As long as it's covered under warranty I won't be scared. That Denali has almost 20k on it so I should be good right? Lol

You won't be sorry. I've thought about ditching my Sierra for a second 6.2. I've found a new Sierra CCSB SLT in Alabama for $41K. I've traded trucks too often though and I'm afraid of the bath I'll take on trade in. :banghead:

I absolutely agree. I knew I wanted one of them when I first saw it. I don't think I'll trade my HC anytime soon, the Sierra however I'm not nearly as attached to.

Really haven't seen too many posts about 6.2 blowing. Any others having issues? If some are going now I wonder what the full life will be with these. The older ones would go past 300k with proper maintenance.

I wanted to alsopint out that GM officially added a 500 mile oil change interval for the Corvette back in December. A few Auto magazines with long-term cars have had their engines grenade. The consensus seems to be metal debris from the manufacuring process as the culprit.

 

How convenient! Just get an oil change with every fill-up! (I know, I know, you meant 5000 miles. :-)

No they really are requiring an oil change at 500 miles for C7 Corvettes. It's likely that the oil is picking up contaminants from the manufacturing process or engine break-in. Maybe the old timers that would change the factory oil extremely early had the right idea after all.

      It was never mandated.  Ever.    Automakers were incentivized to install it by getting CAFE credits to help with their vehicle fleet fuel economy scores.  They were being handed money/CAFE credits to install it.  Which is NOT a mandate.       The current admin removed the incentives that were behind them installing it.

      5 Best Slide Down Gameplay Tips! 

      By lanaderay · Posted

      Are you playing Slide Down endlessly but your score is still low? Are you constantly crashing into obstacles as the game speed increases? Don't worry, this article will share 5 invaluable tips to help you master the race and impress your friends. Golden Rules 1. Look one step further. The mistake of 90% of new players is only staring at their character. The secret of experts is to look towards the top of the screen (where the slide is about to appear). This gives your brain an extra 0.5 - 1 second to process the situation and determine the direction of movement before the obstacle approaches. 2. Use gentle movements; don't swipe too hard. Slide Down is very sensitive. Moving your finger too forcefully or with excessive amplitude will cause your character to be thrown off course or crash into a wall. Practise moving your finger with small, decisive, and precise movements. 3. Don't be greedy for gold in dangerous locations. Gold coins are tempting for buying skins, but life is more important. If you see a gold coin right on the edge of a cliff or next to a spike trap, ignore it. Our goal is a High Score, and your score only increases if you survive. 4. Make the most of Power-ups. During the slide, you'll encounter items like Magnets (attract gold) or Shields (temporary invincibility). Never miss them! Especially the Shield, it's your "get out of jail free card" to help you get through those deadly fast sections. 5. Stay calm when speed peaks. When your score exceeds 500 or 1000, the game speed will be very fast. At this point, don't try to think logically; let your natural reflexes work. Take deep breaths and don't panic. Apply these 5 tips to your next game, and your leaderboard will surely improve dramatically. Good luck climbing the Slide Down leaderboard!

      Why I Recommend a Desiccant Air Dryer for Cleaner, Drier Compressed Air

      By lingyuair · Posted

      If you use compressed air regularly, one problem you cannot ignore is moisture. Water in the air line can cause rust, unstable air pressure, poor tool performance, and even damage to sensitive equipment. That is why I highly recommend using a desiccant air dryer. A desiccant air dryer is designed to remove moisture from compressed air by using drying materials such as activated alumina or molecular sieve. Compared with basic water separators, it can achieve much lower dew points, making it especially useful for applications that require dry and stable air. For workshops, painting systems, pneumatic tools, CNC machines, laser cutting equipment, and industrial production lines, a desiccant air dryer can make a big difference. It helps protect equipment, improve air quality, reduce maintenance costs, and extend the service life of the whole compressed air system. Another advantage is reliability. Many desiccant air dryers are built for continuous operation and can maintain stable drying performance even in demanding environments. For users who care about long-term efficiency and equipment protection, this is a smart investment. When choosing a desiccant air dryer, I suggest paying attention to air flow capacity, working pressure, dew point performance, regeneration method, and maintenance requirements. A good model should match your compressor system and actual air consumption. Overall, if moisture is causing problems in your compressed air system, a desiccant air dryer is definitely worth considering. It is practical, efficient, and highly useful for anyone who needs clean, dry, and reliable compressed air.

      My brand new 2007 Silverado's wax frame was rust from end to end partway through it's SECOND winter here in MA. That stuff is completely useless.

      I went another direction after losing a trailer tire, thanks to not being able to access air at ANY of the 5 gas stations and garages I stopped at prior, with a Toyota Tacoma onboard, 50 miles from the Canadian border. They were either out of order, access was blocked, or the hose a few feet too short and I couldn't get any closer without risking damage to someone's property.   https://postimg.cc/gallery/X5QJ55w
