well i got the official results today, i have a cracked piston. which means that they are cratin' my motor up to go to a gm inspector, who will look for 6 tell-tale signs that it has been chipped, if he find 3 of the six signs, then it looks like i will have a very big bill with delano family motors!

Really curious as to what those would be... I am a Cummins and Caterpillar certified in failure analysis, and you can tell some about how the engine has been run, but proving a chip would be awfully hard to do unless it was set to transmission killing levels...

Cracked piston...Excessive coking on the bottom side of the piston...excessive wear on the crank bearing...excessive wear on the wrist pins....somthin about scoring on the walls of the cylinders, and oil cooked onto the connecting rods. I think i will take another look at the bulletin issued from gm.

No expert here but I think they would be hard pressed to prove that you've had a chip or tuner on it by that.

So all the same signs that would be there if it had gotten overheated towing then? :think:

THATS WHAT I SAID!!! But the sad truth is that i will be lucky if my truck doesnt show all 6 signs, I pull a big trailer around alot! The tech did mention that this is becoming quite a problem on the LBZ's though, not to the extent of the injector failures on the LB7's, but still a problem.

They can't prove a chip with those indicators, especially if you have a hitch. It would never stand up because a stock truck heavily loaded will show all of those in a few thousand miles. Or, high oil temperature will cause all that very quickly. FIGHT LIKE H##L before paying any voided warranty claims.

With thise 6, it just sounds like you used your truck very hard, nothing a chip can add will create those issues, unless that chip had a N2O hook up on the side!

I would get a lawyer IF they were dumb enough to try NOT paying for this fix, but what do I know????/

Chip??? Box??? Power adder??? So let me get this straight. If I buy a bag of chips, a box of kleenex and a bottle of Gatorade and put it in the back seat of my truck I'll have my warranty denied?:D :D

All kidding aside I hope you don't have to foot the bill on this one. GM charges an insane amount for a new Dmax motor. Good luck and keep us posted.

I see you were running a banks big head , I hope you removed that before you brought it in? How much power were you running? Did you have high egt’s? What did you truck do when the piston cracked? I’ve herd that CAT diesels used to have a problem with cracking pistons and it was because people weren’t letting them idle down after hard use.

EFi live, probably around 500rwhp, but only on 3 occaisions, i just perfected my race tune 2 weeks ago! I took the waste gate from banks off, they know nothing of it, And it's not just a matter of showing some of the 6 factors i described, it is how severe they are for the truck only have 63k on it.

So ya pretty near doubled the factory horsepower, cracked yer piston, and now you want the poor General to pay for your sins??? Come on man, that hardly seems fair, does it? And where does the General get the money? Why, it's from the poor farmer who now has to shell out an extra grand when he goes to buy his new truck, which he needs on the farm, trying to make a living, to feed his kids.

I see your point as to what your saying, but the Duramax should take the extra power. It would be diffrent if hes running aftermarket turbos, adding Nos, really going to it limits. But adding a bit more fuel to it, it should handle it IMO.

Somewhere i read a list that gm deemed as a requirement from the jump of the lly's 310hp and 605ft. to the lbz's 360hp and 650ft, it was quite a list, beefier rods, main bearing matieral, head deck thickness, lower compression pistions etc etc....but one would think that there is a small "cushion" there to play with.....

500HP isnt going to its limits??:rolleyes:
I agree it sounds like the piston was a weak one but come
on, Your basiclly saying that as long as we just use tuning
as the means of getting power it should be warranted???
What if I was make a tune that ran 45 P.S.I. of boost, ran 50
degrees of timing advance, and revved the engine to 4500 RPMs
at every shift, (all possible with stock components) that GM
should warrant it when it breaks?? And all this talk about it being
designed to handle the power.... Yeap the LB7 was designed to take 300HP/520LB FT, the LLY was designed to take 310HP/ 610LB FT, and the LBZ was designed to handle 365HP/650LB FT PERIOD.

Thats what i think, Personally, I could care less to what you think. I understand he was running McRats race tune. I dont know if McRat pushes the turbo to its limits or anything else with that tune. But it should of held a simple 500 RWHP tune. Simple...:)

Just because most duramax's do, doesnt mean it "should".
I am not trying to be argumentitive, simply stating what I feel is fact.
If the piston would have cracked with stock tuning, then it should be replaced under warranty, if it would have lasted to 200,000 miles or more, then GM should not have to warranty it, but that becomes the "gray area". Because there is no way of knowing how it would have held up to stock tuning over the long haul. Doubling the horsepower of something and
expecting it to live, I dont think its quite as "simple" as you think.:)

X2!!! :exactly:

To have a failure on a truck with a wild tune and no hard part modifications (like rods, pistons, etc...), and then whine when GM doesn't want to pay for your sins is a lot different than running a chip and towing hard. The piston probably wasn't a lemon by stock GM design standards...

You should be very grateful if they do ANYTHING for you, and be very happy it didn't have a bigger failure.

My 2 cents

I'm starting think there is a QC problem with the LBZ pistons. There aren't that many hotrodded LBZ's yet, but that's 3 failures in a short time. There are literally hundreds of "tuned" LB7 and LLY's with few problems.

We are starting to disassemble Casper's old engine, and the pistons look like new.

McRat, How do you feel on the effect of your tune on the stock Duramax components? I know it will decrease longlitivity of the motor, but crack a piston like this guy? It just dont seem like it should do that with alot others running your tunes and no problems to date! But, i dont know, im by no means a diesel mechanic, or a knowledgeable person on a engine.

I understand some of you guys, but i normaly have it set to stock, or 50hp form the hypertech, and i tow in excess of 22,000 all day long 3 days a week, and it didnt even happen when i haad it tuned up, i was runnin it stock power that day, and it let go and started shakin when it was sittin there just at an idle. I wasnt even in the truck!! I know this is a gray area, and i dont think they should have to fix it, but boy would my wallet appreciate it if they did. And i dont run mcrats tune, i run my tune that is in the repositry. And if any of you do have mcrats tune, i would appreciate it if you could look them over and let me know how they compare, i am tryin to decide if i should buy it from him or not.

We run the same LBZ and LLY tune we send out to customers on our own trucks and drive them daily. About 150 trucks perhaps with maybe 50 LB7's.

I guarantee nothing I sell will increase the lifespan of your drivetrain, but failures at "500hp" is new to us. Even on the "650++ stuff" cracked pistons aren't a problem on fuel. Well, until now.

I tell everyone that doubling the stock engine output is not "safe and sane", but the risk is actually low so far. Tripling it is a problem. :D

That is what makes me think you had a bad piston. A bad casting that was either contaminated or had a void.

My truck has not had a small tune in it for a good while. Daily drive, hauling towing, sledpulling, drag racing, etc. All seems well with 80k on the clock.

I've seen cracked pistons on stock engines and with 40HP tunes. Nobody is absolutely sure why. It's rare like valve train failures, but it happens.

Wow, This would be harmful for the Duramax...I thought the LBZ was going to be the one with NO issues. Well, Besides the Glow Plug Recall; The LB7s had injector problems, some LLY's were overheaters...Maybe the LMM is problem free :D

If the LMM is as similar to the lbz as i have heard, then i imagine that it will have the same pistons, i.e. the same problems with cracking them.

Just like anything, there is always a few that have issues. I can tell you the cracked pistons in a LBZ are actually very rare. I can't speculate as to what happened with your piston but I can tell you that GM will do everything they can to get out of the warranty. Cummins and Ford are doing the same thing when it comes to warranty. The only way things like this get resolved is with a attorney. It sucks that's the GM field reps feel the way they do but they consider the diesel owners a pain. That's from first hand experience with dealing with them.

No. Don't tune your truck and ***** about a factory defect. I know you don't want to hear it, but that is all part of doing what you are doing. I took my truck in a few times for warranty repair. I tell them what I did, they decide if it is worth their trouble of dealing with. The other day my radio went out. They covered it. That is one of very few stock parts on the truck, but an issue that was not caused by any of my mods. If I go in with bent rods or a broken piston after tuning the truck and they deny my warranty, it is time to suck it up and pay the bill. It is a tough bill to swallow, but that is part of the situation you got yourself into by modding your truck. You might feel unlucky, but you chose to do the mods, not GM. Keep it stock if you don't want to pay for GM's mistakes. This is your fault weather you like it or not. Pay up.

The Magnuson Act 1975- Was passed by congress and was designed to give customer's warranty protection. The Act is administered by rules established by Federal Trade Commission(FTC) and provides a number of remedies. With rare exception, a purchaser of a warranted product is not required to buy an item or service from a particular compant to use with the waranted product in order to be eligable to recieve a remedy under the warranty. In addition, the FTC says a warranty need not requir use of spcified replacement parts, repairs or maintenance that is innapropriate for any prodduct, but many reccomend using authorized service dealers and that improper or incorrectly performed maintenance or repair may void a warranty. Finally a legal dispute, the onus is upon the warrantor to establish that any unathurized modification was the cause of a warranted product failure in order to void the warranty.

There's nothing in there about it being all fine and dandy to mod the **** outta your truck and then jump on the manufacturer to fix an oops. Now, if all you've done is a little EFILive, it'd be hard to blame that for your problems, but it IS possible... Personally, I've never heard of a pison cracking on a factory truck ever.

I agree with bobo, and I've said it a hundred times before and I'll say it again- if you want GM to cover all of your mess-ups and "learning experieces" under warranty, you'd had better never complain about increasing cost of service, parts, and ultimately new vehicles.

Ok, so the dealer quoted me almost $16,000 for a new motor installed. I asked them if they could just put my motor back togather for me to pick it up, they told me that i would have to pick up my vehicle as is with the motor in pieces, that gm would not allow them to re assemble the motor. Now am i correct to assume that this breaches our verbal agreement for the original $4677 for the "TEAR DOWN AND REASSEMBLY OF YOUR(MY) VEHICLE FOR DIAGNOSTIC PUPOSES IN THE EVENT THAT IT IS NOT COVERED UNDER THE POWERTRAIN WARRENTY". So considering he breached our verbal agreement, not me, and it was verbal so there is no fine print to worry about, I do not have to pay the $4700?

Well you could do this maybe. Have them give it back like it is, put in a new slug if the bore is ok and put it back together so your truck is functional. Then detune it until you have enough for a build then again who knows maybe it will live with your tune and just a new slug. Just an idea.

Thats a great idea, but i havnt the slightest clue on how to put it back togather, and i still have yet to find a shop around bakersfield that will even touch a diesel. They are literaly going to give me a box full of parts, with everthing from head bolts to intercooler boots in it!

I would request that they label a box with each part and origin it belongs so that each part is counted for and nothing lost or forgotten. You could buy a used engine and put in your truck to get it going first. Then depending on funds either take your motor thats torn apart to a shop to reassemble and then sell it to recoupe some of your money or build to make stronger so you have a spare.

So what did GM find that made them decide to not cover it under warranty?

I have a guy that will put the engine together right in Riverside County.

There's nothing in there about it being all fine and dandy to mod the **** outta your truck and then jump on the manufacturer to fix an oops. Now, if all you've done is a little EFILive, it'd be hard to blame that for your problems, but it IS possible... Personally, I've never heard of a pison cracking on a factory truck ever.

I agree with bobo, and I've said it a hundred times before and I'll say it again- if you want GM to cover all of your mess-ups and "learning experieces" under warranty, you'd had better never complain about increasing cost of service, parts, and ultimately new vehicles.

It doesn't say in their you cant mod the **** out of you truck. If your brain functioned correctly when you read it you would see their is law stating you can put what ever you want on the truck. Furthermore you would of got the point which is if they cant in a investigation prove that what you put on dirrectly damaged a part they have to warranty it. No more showing up to a dealership getting denied warranty work because of Major or Minor modification to the vehicle.

I feel the true intent and meaning of that law is to keep manufactures from demanding their overpriced parts ONLY be used on any vehicle to keep the warranty valid. This goes from oil filters to engine hard parts. Having a case of a piston failure in court when you have modified the stock tuning parameters to double the stock hp and tq on an engine hardly qualifies under the law. If you choose to pursue it, I'd imagine you have enough money to piss away on a new motor too. It would not be worth the expense and stress of a trial, IMHO. Fix the motor and go on with your life.

Can they tell what level you had the chip on or what kind it is by looking into the computer? How can they prove the chip single handedly caused the cracked piston? Not letting the Dealership or Manufacturer **** you over is more important than $. The more people that dont challenge these decision's of whether to warranty or not by the power's that be is the problem. Just because the dealership or manufacturer say so dont always make it right. :)

Oh well, i got the bureau of automotive repair involved, and we were able to adjust the cost down to a reasonable amount. Only $2k to get the truck home in pieces, i not gonna complain to much, i believe this was a fair amount, if the bureau can bring it down anymore, than that is fine, if not than that is fine to.
