Sounds like you have a viable solution to a costly problem. Wondering what your total cost will be, as it sounds like a more permanent fix than merely replacing lifters/camshaft, knowing subsequent failure is all but guaranteed.

Hope this repair/upgrade works out for you.

 

2010 5.3L 77k MILES.
All the stuff done over the years
2 years ago new pistons job.

Now rough idle. Pulled plugs. White part looks clean- no oil.
But down into plug sides are heavy carbon coated.
Still have 2 warranties. Factory and Major Guard.
Had closed but can reopen CAP case.

Sad day as I see this engine may be a lost cause.
Dealer said bring in next oil change as not a hurry- No CEL.

Lots of questions need to answered. What is problem are how real is it?
Then what options GM will offer.

My wife says junk it. I say all I need is new Create engine. Brand new with 5Y- 100k warranty. I would be happy as hog in mud. I like the truck. But I am scared what will happen after warranty is gone. No money for fix on my dime.

 

Bob,
I was in a similar situation to you. If I was you I would do what I did. Forget about the old style engine. Your 2010 is probably worth close to $15K-$20K. Chevy is still giving good deals (about $8K) on the new models with newer engine and bigger interiors. I got a 2014 from my 2009; and lowered my monthly payments too! Do the math; split the difference on the trade, $18K plus the $8K and on a $42K truck, you are looking at $16K to finance for a new model and a better truck!

my 2010 has 170,000 miles on it. Sent the oil into Blackstone labs with 7,500 miles on the oil. They said that it looked like it had come from an engine with 5,000 miles on it.
GM has changed it every 8K

 

And how is this contributing to the thread? I mean, we are all happy for you that you are not one of the tens of thousands that are negatively impacted by Chevrolet's lack of action to this problem, but your comment seems rather self serving.

 

It contributes by letting us know that not all engines are affected or are doomed.... I will be turning in my sample for my 2007 with the 5.3 to Blackstone in about another 1500 miles and am hoping for similar results at 109,000 miles... I added an AFM disabling tuner and am expecting to see much better results in the oil readings...

 

@Philntx: Great for you and I am glad your 2010 has given you good service. Having gone thru the nightmare of having my truck shut down on an Interstate from 65-70 mph, I would not wish that on anybody. Especially someone older or disabled like me. That's why I won't recommend dropping in a new engine or getting it repaired (unless you are a mechanic with access to cheap parts/labor or you are a big shot at Chevrolet) to anyone I know.


@in2pro: Now the post by the administrator is really out there. I am not advocating anyone think their engine is affected or doomed, only to those of us that it has already happened to. However for in2pro to minimize the problems, while at the same time DISABLING the AFM feature is disingenuous (there are other stronger words) at the very least! What a load of crap!


That is like what happened when the computer sensors on your anti-lock disc brakes malfunctioned in the past and your mechanic tells you, that you can disengage them and the brakes will still work! What a load of BS. You should not have to disengage a major feature on your engine in a $30,000 vehicle to reduce service costs. That is the most telling part of in2pro's post, that he had to disable the AFM feature to avoid problems, instead of FIXING the problem.


Just letting everyone know that I am 60 years old & still believe in Chevy, that's why I bought another of the same exact vehicle, just a 2014 model. My first vehicle was the 1962 Impala with the 283 engine, through a Caprice, another Impala, couple of Trucks, couple Blazers, and a

Exactly what is it about my post is disingenuous or a load of crap?!?

The earlier models of the 5.3L AFM are known to have issues, I experienced none in the first 100k miles or the 8 years I have owned her.
Knowing that the AFM that was used in earlier models, can be prone to failure, I opted to be pro-active and used a turner to remove the feature so I won't suffer that problem should mine be one of the unlucky ones, so disabling it IS very much a viable fix, as it removes the AFM feature preventing the engine damage, and the tune also removes a percentage of the torque management and improves shift points..

The fix is the rebuild/replace the top engine with new lifts and cam... that's not a project I want to take on with my daily driver. If you are expecting me to jump on the GM bashing band wagon, I'm not going to do that either, this is my 6th GM vehicle and I have no complaints about any of them...my first was a 1973 Grand Prix with a 455...

in2pro,


I am not going to spend time here debating the practice of disengaging engine or vehicle features that are major selling points to the consumer in the first place. That is not being pro-active. If you cannot understand that general point, there is no point in going further.


Suppose one of NASA's rockets had a design flaw that they burned up by exceeding the speed at which they normally operate. Then an after market company made a governor on speed, so the rocket could not go above the speed danger level. As an analogy are you seriously telling me that is a pro-active fix/solution?


Oh I am very much aware of the fix. It happened to me with about 28,000 miles and kept my truck in the shop for 10 days! Also where in my letter am I bashing GM? Did you read my entire post? Did you not see where I bought another Silverado Crew Cab? How is that bashing GM?


As far as being a moderator goes, so what? I am a moderator on a number of firearm sites and I am unpaid as well. But I would not advocate after market fixes when a company has no intention of fixing the problem in the first place.


That's all folks!

 

So exactly what do you advocate? Those that suffer the failure just live with it, or shell out the $4k for a new engine every 100k miles… You just said you don’t believe GM has any intention of fixing the problem!?! ( it was resolved in later models ) So why wouldn’t someone seek out an aftermarket fix?


Would you feel better about it if it was referred to as a work-around rather than a fix….
