More is always better.

Not for everyone. Lots of people are happy with the 5.3 v8. and of course its the most common V8 in any GM truck. Everyone has one they are a dime a dozen.

 

[RedSLEd]

I have a 5.3 in my '13. Do I wish I had a 6.2? Youbetcha! I've always thought it best to get the biggest/most powerful motor available in a given vehicle.

BUT... I'm glad I don't have to buy premium fuel when it's $4.50 a gallon. It's already over $3.00 'round these parts. It will be pushing $4.00 come July. And with creepy Joe in the big chair, it could be $5.00 next year.

 

[MotorEng91]

Man, I really hope that doesn't happen. But if 87 octane is $5.00 and 93 octane is $5.50, its only about $10/tank difference still

I saw a 6.2 blow apart a piston i was like hmm that aint good. Which is why i am a little concerned

 

[green02crew]

I've spent a good amount of time behind the wheel on nearly every iteration of these engines. The new 10 speed behind the 5.3 is nice but the 6.2 even with the old 8 speed just rockets. The 6.0 is hearty but bagless. You can run regular in a 6.2 but you will lose a little performance from retarded timing unless you run it cooler. The 6.2 tows better than the 5.3 or the 6.0 but if you want 6.2 power and 6.0 longevity, the new 6.6 gas is your answer.

I follow this guy on YT that salvages engines. He's tearing apart a Vortec in this vid, but he says the most common coffin nail is cracked piston heads. Kinda fun to watch the pieces of raw metal fall out of the block on this one.

I suppose if you were really THAT concerned, a vehicle with any moving parts that can explode due to chance, poor maintenance, etc should be avoided. How much is a bus pass these days?

i don't care about engine blowing up seen it plenty of times. But a new 6.2 V8 blowing a piston inside the block damaging a cylinder wall right after a fresh solid rebuild that seems a little fishy to me. And yeah I'd save alot of money in gas with that bus pass how bout you?

There has to be a reason as to why a 6.2 Eco tech motor is having issues. Have you seen the 6.2 page on here ? Bent rods, loss of power, on and on and on. There musta been a bad batch in the production or something I havent seen an old LM7 5.3 cause that many issues nor have i heard about a 5.3 causing alot of up roar other then the AFM sucks in some motors rather then others. You see my point? Catch my drift?

 

[MotorEng91]

I see your point. The reason may be that people drive them hard because they have more power. Not trying to be argumentative but if I had a 6.2 I may be more likely to race it around than a 5.3

 

[jrabenaldt]

I'm one of the recent 6.2 lifter, injector, pushrod victims. Mines paid for and isn't driven like a rental. I want this thing to last but anything mechanical can go boom!

I know a guy who's 2015 or 2016 Denali (can't remember which) threw a rod at about 50K miles and had to have the engine replaced. He traded it in for the new Ram.

 

[crazynights]

I unfortunately am also a current owner of a 6.2 which has the 8 speed tranny issues and now is at the dealer for the Code P0300. 21k miles and the check engine light appeared. Made the appointment and went yesterday to hear about the code and how it's a misfire in the injector. I looked it up in more detail and it doesn't look good. This 6.2 was bought with 15k miles and a range was put on the day I bought it. Very disappointed as my 2007 NNBS was traded in at 150k miles for this (so wish I kept it) and never an issue. Guess my truck is part of the bad batch.

 

[10speedr]

My 2010 6.2 has been bullet proof. Just about to hit 80k miles.

Other than basic maintenance and fuel, I have not had to throw any money at the drivetrain to keep it on the road.

You got me looking and he just did an L86 EcoTec3 6.2 a couple days ago

Broken valve spring, broken lifter, valve hitting the piston, bent push rod. Wonder if it was AFM failure...

 

[jrabenaldt]

On mine last month they replaced 4 injectors, 4 lifters, broken pushrod (the pushrod happened on the test drive after replace the 4 injectors first and all of this on the right side) and the VLOM.

But it started with running very rough and an error code on cylinder 4.

Oof that hurts. How many miles did you have? Was any of it covered under factory warranty?

 

[jrabenaldt]

I bought it 2/2020 and added an extended warranty before walking out. No factory warranty coverage remained since it had 46k on it. The motor issues happened with 56k on it.

And even with this, the condenser having been replaced along with the front Magneride shocks (I did the shock replacement) this is by far my favorite truck.

 

[SuperOldSchool]

92k on my Yukon Denali

I had #6 lifter break. Replaced only the one under warranty
#5 injector failed
2 fuel pumps
Tensioner failed
Battery cable/ harness
Radiator
AC Condensor
HVAC fan motor

Engine wise it's been ok, but lots of other issues before 60k

New trans 15k
3/4 MRC struts replaced
New exhaust system
Many sensors replaced
2 headlight/taillights
GPS antenna
Prob more but forgetting

A lot for a freakn' $70k+ vehicle

In the next few years I was thinking of upgrading to a Tahoe, Yukon, or another Silverado or Sierra. I have heard a lot about the 6.2 v8 motors and I see some posts about some issues people are having. Are these motors pretty good or would it be wise to steer clear from them? I do have 3 trucks in my possession right now with the Vortec 5.3s. Of course the Vortec and Ecotech engines are similar but I am just curious as to how reliable the Ecotechs are. Sure all vehicles will have some issues but I would like to try a 6.2 I hear they are beasts and the 5.3 Eco tech are very nice too but not as much power of course, but they still get the job done!!

I here the 6.2 is blowing engines at 8000miles and 5000miles. I wouldn’t touch it with a yen foot pole!
