New Pistons And Rings Done, NOW I NEED HELP!!

[jacjac171]

Well, I sure could use some help right now!! Ive got a 2011 Chevy Silverado crew cab Texas edition 4x4 truck. I bought the truck new in 2010.

The other day I was driving my truck and my speed was approx 30mph. I was doing a slow acceleration in the truck at the time. All of a sudden I lost power in the truck and like most others say it(truck) entered a "limp mode". I was able to drive the truck back home as I was only a mile away from there. After a few days I decided I needed to take the truck in to the dealership as I'm no good doing any kind of work on any vehicle plus I'm fully disabled.

 

I dropped my truck off at the dealership and was told it would be ready later on that day. At 5pm I received a call from the service department and was told they were still looking at the truck. This was on a Tuesday. On Wednesday I received another call from the service department and was told my truck had a mis fire in the engine. They said it would be a few more days until they had it fixed. Finally on Friday I received another call from the service department and a I was told the truck was ready.

 

When I picked the truck up, no one said anything to me as to what they did to fix the truck. I did get the paperwork on the truck when I signed for it and picked it up. The paperwork stated they had to get into the drivetrain and tear it down! They stated they replaced the pistons, rings, gaskets, bolts, and so on. They also had to do an oil change as well. All of this was done for an engine "backfire"?? None of this makes much sense to me, but like I say im not a mechanic by any means.

 

Ive read so many bad things in the forum from other Chevy owners about the known issues with these trucks and years of them. From the oil consumption issues to the loss of power issues as well as the problem a I had. What I'm needing to know is this. And let me STSRT by saying ive already read two other post where two different owners said that by having the pistons and rings replaced hasnt fixed their problems. So thats my question to anyone that can help that knows a little something about this mess. Since the work was done, and thank God it was under the powertrain warranty with one month left before it expired! But after having this work completed should I feel safe that the truck is now fixed of this entire issue, like with the spark plugs having oil all over them and the mis fire. I'm assuming that a vehicle can have a mis fire at any time but to have a mis fire like mine did along with this massive repair it just doesn't make sense to me. The total on the paperwork was over $4K!!! I'd be so upset if I keep the truck and then something like this turns right around and happens again. The truck only has 27000 miles on and its five years old based on me buying it in 2010. And as you all know its not a cheap truck esp being the Texas edition!

 

So should I feel comfortable that the work that was completed fixed the problem with the mis fire and that I wont have something like this happen again esp something with cost like this? I know no one can tell the future, but someone out there that has more info on this than me could maybe offer me some advise. I hate to sell the truck, not because a i love it. As I dont love the truck at all its just transportation, but I really dont want to have to deal with selling it and buying something else. The truck has been paid for, for awhile now. It still dealer books for $27000 and to an individual like $31000. So a I guess id have a good down payment for another vehicle but being disabled now, its so much harder for me to get around much less having to deal with sales people!

 

So any help from anyone on this topic would be greatly appreciated! Thanking you all in advance, and please no picking at me for not knowing much when it comes to motors. My dad was never around so I never got to learn this stuff when I was younger. I know I could have taught myself some of this stuff but its much easier to learn when you have someone right there with you to show you this kind of stuff. So thanks for the help!!

All the work wasn't for a backfire per say, rather a very heavy misfire on one or multiple cyinders, specifically the AFM cylinders. The dealer should have installed all of the latest AFM upgrades (oil deflector in the pan and drivers valve cover) when they had it apart. I'd drive it. If you are worried you still may have a problem, you can buy a Range AFM disabler or drive around in M5 manual mode (around town, as on the highway your MPG might suffer).

[jacjac171]

15HDriver, first thanks for the reply! This is what was written on the paperwork that I was given at checkout.

 

CA-46

 

Found several cylinders have oil fouled plugs, found oil control rings failed causing cylinders to have oil consumption issues. Replaced all pistons and rings, all gaskets and bolts and O rings, refilled coolant to proper level cleared codes and checked all pressure drove to verify all repairs.

 

The following are the items they replaced: pistons, gaskets, bolts, cover, seal, gasket KI, spark plugs, coolant, filter, dexos oil, bearing K, seals, then more gaskets.

 

So I see in the list of items they replaced they make mention of a "cover". But what I don't know is if its the same cover you made reference to. I've got no idea based off whats written on the paperwork if the AFM upgrades were completed or not. Based on the information that I provided to you, which is straight off the paperwork I was given. Does any of this sound like they did what you're saying should have been completed?

 

I've read here on the forum all about the oil deflectors and that stuff, and man what a bunch of issues they have had with our trucks for sure! I've also read about the Range AFM disabler. So if I was to get one of those put on, that would mean I wouldn't have to mess around with the manual mode, Right? Then also if the disabler was installed I wouldn't have to worry about the highway speeds or the MPG Right? Sorry for being such a dumb butt, However I did warn you at the get go that I don't know much at all when it comes to this stuff, I turned my man card in when I became a member here. I was told it was mandatory, LOL.

 

The disabler should not be at my expense, correct?

 

So my other question for you is this. With all the items they said they replaced, should I be concerned about issues in those areas anymore? I'm not holding you to any of your opinions but you are the one that knows this stuff and not me so I need all the help I can get! Also, how long of a time period would you think the work they did would be covered by any type of a warranty? Like I said in the OP, the bumper to bumper is totally expired now. The power-train has about two weeks left on it before the truck is officially five years old. I've read so many bad things about these trucks here on the forum. I've read so many bad things that if I had known about this website I would have never purchased the stinking truck in the first place! I really hate trying to sell the truck as well. And like I said it's not because I love the truck either. Ive also got a 07 Ford crew-cab and I do love that truck but Ive given that one to my son to use.

Again any help from you as well as anyone else is greatly appreciated, thanks again for your time to do the response to me, have a great day!

What my plans are, is to get as much info as I can from you as well as any others on here. That way I have my ammo all ready for when I call the dealership back. I want to sound like I know a little bit of what you're talking about so I don't appear to be so dumb on the subject! I just want to make sure that the problem was addressed the right way as you have said it needs to or should have been done. I just don't want anymore problems with these same issues again as I'm sure at that time the rest of any warranty will be expired. This work they have already completed was well over $4K so far! I can only imagine what my wife would have said if I would have waited any longer to take this in for the repairs. If I had let what little bit of warranty thats left expire!

Sorry, one more thing for you. One thing that I had read on the forum was from two other people that have gone through the exact same thing as I have gone through. Both of the other people said that with them having all the same work done as I did, they both still have the same issues going on!

See my deal is, I don't know what issues I've really got going on except for what the dealership has stated about a "mis fire". So with what I've provided here to you, does it sound like I've got the same problems/issues as others have stated they have with their trucks when it comes to all the known problems with the oil consumption stuff or whats your thoughts on that? Man I owe you big time for your help,again thanks!

[jacjac171]

Is there anyone else out there that can help me out with anymore info or personal advice, thanks!

Range AFM would let you drive around in normal D so yes, you wouldn't have to drop to M5 and drive around, it will disable AFM all together. Unfortunately, disabling AFM would have to be customer's expense as GM does not support any devices like that for tuning/disabling features they have in the vehicle, so it would be something you would have to buy. I have read a couple of people having oil consumption issues after repairs, most of them are higher mileage than yours of those that I have read. Disabling with a tune or the Range device would be the best thing to really put any future issues to rest and give you piece of mind. The ones that have had repeat oil issues also didn't have AFM disabled, they left it alone.

Thanks for your last response! Since I've had the truck back I've had some NEW ISSUES pop up! The other day when I was driving the truck I came real close to rear ending another vehicle in front of me! I was approaching the rear of this vehicle as it was stopped at a red light at the intersection. I usually never drive my vehicles fast and I actually baby them a lot. Anyhow, as I was driving I observed the light at the intersection turn red. I started to slow the truck by first getting off the gas. Then I started to apply the brake in the truck. As I got closer to the rear of this other vehicle that was stopped at the light, I noticed my truck was raising its RPM's. As I got right to the rear of this other vehicle, luckly the brakes did stop me before hitting this other vehicle! But what happened was when I got off the gas pedal and then started applying the brake like I said the RPM's increased and reved the motor. By it doing that, the brakes almost didnt stop me in time!

 

After that little issue, I made sure to give even more time and space then I normally do when I approach another vehicle. So now ive had that problem, Im also having shifting issues! When I accelerate slowly as well as even a faster start, the truck has some issues around second going into third gear. Its a very rough shift and at times will make a "thunking" noise! Ive read here in the forum where other people have had these same issues happen as well.

 

With that however, I've never read anywhere what the issue was or why it started as well as how it was fixed. This is a huge safety issue and I'm wondering why GM has never addressed the part where the rpm's go up making it hard to brake. It just doesn't make any sense to me that I should be having so many issues out of a truck with such low miles on. It just turned 28K miles the other day! I wish someone from GM would respind to this thread and offer me up some info. I've seen in here before where a GM Tech has responded to other threads so I'm hoping one of them will take some interest in my safety issue!

 

After all of these things have been going on, the other day the manager from the service department at the dealership called me. He left a message asking me if everything was ok with the service that was done on the truck. He also said id be receiving a survey from GM about the work that was done. He couldn't have called at a better time as I was setting up a time when I could call him anyways to discuss these new issues that have popped up. I still want to know why all that work had to be done to my truck for it just to have had a misfire. I havent had anyone tell me that the work that was done was needed for a misfire. None of any of this stuff makes any sense to me. The problem with this service department is when they talk to you they talk really fast. Its very annoying for someone to talk fast to someone when the person who is having the issues doesn't understand a whole lot about vehicles in the first place! Anyhow, I plan on calling the manager back today. But in the mean time, IF ANYONE COULD HELP ME ANYMORE THAN WHATS ALREADY BEEN DONE FOR ME ID GREATLY APPRECIATE IT!! Also if anyone knows how to get some attention of help from a GM Tech or a Rep for GM id really appreciate that info as well! Thanks for the help and im glad this forum is here to help people out, THANKS!

so, your warrantee just ran out?

 

Only time my truck revs when I step on the brake is if my foot is also pressing on the accelerator pedal as well.

[jacjac171]

Well of course the warranty just ran out! Isn't that the way everything goes, LOL. Actually the power train had 2 weeks left on it so the pistons and rings were all covered. I don't know what they plan on doing though with the new issues that are now surfacing!

And NO, I'm not touching both the brake and gas pedal together, LOL good one though! I know you said thats what you have done but nope not me man!

It can easily happen w/o you even realizing it.

What's with the AFM talk and worrying about updated AFM parts on an HD truck?

None of the 2500HD or 3500HD pickupd used the AFM engines.

 

......... I guess this topic is just in the wrong section because that mentioned Range gadget does nothing for any engine offered in the HD's.

It's a trickster device for AFM equipped trucks and will not work on a 2500-3500HD.

 

OP, what is the make and model of the truck you are having issues with and which engine do you have?
