Gm will pay for it in lost sales to Ford and Toyota. The elephant in the room is the Active Fuel Management system that causes premature lifter failure, high oil consumption and untimely engine rebuilds due to gummed up piston rings.
When there is a plethora of aftermarket parts developed like the Range Technologies plug in module, and AFM delete kits, then thats a sure sign of an engineering failure. (In an exaggerated Hispanic accent, mileage? We don't need no stinking mileage. We don't care about a mile or two per gallon, what we do care about is an engine that doesnt disintegrate before 100, 000 miles!
Furthermore, if someone is looking for a low mileage 20008- 2012 used GM truck, they'll also have to contend with cracked dashboards, shoddily designed door handles, and difficulty getting replacement air bags.
GM did it to themselves, they had an opportunity to make a dependable 5. 3 liter, but they squandered it.

god, this video helped me so much. So simple yet clear. I just purchased a re manufactured motor from advanced powertrain solutions. Stay Away! I had just primed the oil pump and was just adding coolant when bolt #14 had a leak on the passenger side. I hadn't even turned the motor over yet. It already had a leak. They wont fix it. They are providing me with a 50 hour labor rate and a all data 8. 1 hour allowance. I live in california. Our minimum hour labor rate are much higher than in most states. let alone skilled licensed employees. I cant find a shop charging anything less than 1600 to do just the labor.
I was skeptic about a crack in the head. This video made me a believer Thank you for sharing this with us.

I have found that the 100k super long life coolant has smaller molecules and Will find a way to leak or find a porosity problem sometimes if you switch to the old Green coolant the problem no longer exists but you do need to change your coolant more often

Awesome video. I Wish i would have watched this vid before ending up 50 bucks poorer and wasting two hours pulling intake manifold only to realize the intake is a dry head. Guess thats what happens when an I&e tech trys to play mechanic

I thought this only happened on heads with the castech symbol? I just bought a used motor with 862 heads that does not have the castech symbol. I thought I was in the clear but now Im worried.

Love my Toyota vehicles. Learned my learn 25 years ago. Buy Toyota or Lexus vehicles only. None of my Toyota vehicles have ever left stranded on the side of the highway.

I have one now leaking. It's also the passenger side only. Is it safe to only replace that one side without touching the drivers side? Thanks for any help.

If you leave this leak go, where does the coolant end up going? Out the exhaust and intake valves? Would this show same signs as a bad head gasket?

Hey, do you have the follow up video of replacing the heads? That would be HUGE. As always, thanks for all you great videos.
