So they (you) were not talking about catch cans voiding warranty and being an illegal emission modification?

? 

 

And when did I spank you? 

What disagreement have we had? 

?

Or am I learning something new about you?

no problems with you, just commenting on old guys in general and the other member posting between you two

Grumpy Bear is correct. Now a dealer or GM can choose not to work on a modded vehicle or blame the mod even if the catch can wasn't the issue. Then it is on the customer to fight them in court using the (Magnuson–Moss Warranty Act) which is absolutely the worst thing in history to see quoted on forums when people talk about fighting dealerships. Who in the world is going to spend the money and time to fight in court over a broken lifter or hell even a whole engine? Even if you win you will still loose. That is why it is ALWAYS safer not to mod if your worried about it rather than believe the act can protect you.

It's not as hard as it sounds. You don't have to prove anything. They have to prove the aftermarket product caused the failure. All you normally have to do it call their bluff. Hire a lawyer. He writes the letter. You pay him an hour or so. The cost of proving the causes on the OEM, not you. That cost is high. Normally higher than the repair and they know that. But most people get all nervous and fold. They know that too. Stick to your guns. They have nothing to loose and everything to gain by testing your resolve.

A catch can is nothing more than a liquid separator. Does NOTHING for the PCV system as far as functionality. It does provide for a treacherous path for oil vapors trying to get into your intake system. (provided you get a worthy canister).  It is not required for your engine to run. The engineering team somewhere along with the bean counters decided that the engine is operational and meets current federal emission mandates as built.

 

It's similar to a water separator for an air compressor system. You know, the one that takes out water from the air line? Pull it out, and the unit still works. Why run a water separator anyway? Oh, yeah. To keep water from getting into your air tools or paint job. If your pretty sure your air is dry, you don't need one do you? How long will that take to kill your air tools? If GM was betting on it, probably longer than the warranty period. Who really knows? 

 

So people put water separators in their air lines to keep water from doing downstream damage. Same for people running a catch can to keep oil from ending up in their intake system and on the wrong side of the pistons.

 

Nobody is making anyone use one. You do it because it helps you sleep better at night. If you trade up every few years, then don't worry about it. The cool thing is, if you install one, and get basically nothing, you can always take it off and sell it. At least now you know how much you're sending through to the intake.

 

But with a can, the engine will see a decrease in oil depositing in the intake system, but still, that won't address the fact the oil you collect would normally have ended up in the combustion process if you haven't looked. You're just catching it before it burns. So if you're emptying it way too often, you'll have bigger fish to fry. And if you feel like you're going to lose a warranty over the mere existence of a can, ensure you restore your hoses back to OEM configuration before taking it in. Get some hoses that use the factory style clip points and it's a quick snap back into place and nobody's the wiser. Or make sure the service department folks are on your side when it comes to the catch can. Yeah, aftermarket parts are not supposed to be an automatic warranty void under the MMWA. But some service writers are A-holes and while they may be in the wrong, once they flag you for a voided warranty, good luck getting that restored. 

 

But with catch cans comes great responsibility. You need to check it periodically and adjust the check intervals accordingly as to how much is collected. The last thing you need is to never check it and have it fill up and spill over into the intake system.

This was a topic on results from my catch can, and invite others to share theirs.  There are other threads dealing with pros, cons, and right or wrong.  If y'all want to talk about that, cool.  Go have your "who's is bigger" contest  in the appropriate thread please.

Hey I'm just sharing what my dealer told me. Take it for what it's worth, go ask your own dealer, whatever, I don't really care.
My dealer told me that if I installed GM Accessories on the very vehicle they are designed for, my warranty is expired. I can give you the dealership name, employee name, their email address, and the dealership phone number of you don't want to believe "some guy" on the internet. Dealerships aren't reliable sources. When i want to discuss the law I'll seek info from an attorney. Oh, wait! I have. Per the Magnuson-Moss Warranty Act, the burden of proof is on the warranter. GM, or one of GM's techs has to prove a modification to a vehicle caused a failure of parts seeking warranty replacement/repair in order to reject/deny a warranty claim. Spraying nitrous oxide into an engine, and frying the piston rings, will void the powertrain warranty. Installing a catch can in line with an air tube to prevent oil from going into the air intake via the throttle bottle is an improvement to the longevity of the vehicle, not a hinderence. GM would have a very difficult time defending a denial of warranty in court on that one. Not only would they be compelled to honor the warranty, but they'd also have to pay for legal expenses to the plaintiff.

If you think you want/need a catch can and you worry about warranty, just uninstall it everytime you go for a warranty claim.

 

They really are very easy to install/uninstall.

 

The dealer will never know you had it on your truck/car.

Loss of warranties due to catch cans do happen, although it rarely happens. Or rarely talked about. Don't know which. Usually the voids are from stupid dealer techs who don't have a good understanding of the systems and start blowing whistles because it's easier than trying to correctly diagnose issues. MMWA is only worth it if you have enough money to waste on a lawyer. There's what MMWA says, and then there's reality. Good luck.

 

Unfortunately, every catch can thread evolves into a warranty discussion and/or whether you feel you need one or not. It's going to happen. Every. Single. Time.  Looking at pictures of 1/2 ounce of oil gets boring fast. Discussions go astray. It always happens.

 

My results? I don't drive with my foot on the floor all the time so my canisters don't fill up with more than a thimble full of oil at most between changes. So I'm not going to post any pictures unless it's more than a Bounty towel wipe up. Maybe I got lucky. Who knows? But I can rest easy knowing my intake runs cleaner than most.

 

You're doing the environment a big favor by the oil collected that would otherwise coat all the wrong things in your engine and get burned and tossed into the atmosphere. One droplet at a time. Consider the old PCV systems of yesteryear used a pitot tube that went down the back of the engine and air flowing over the end of it drew out the engine pressure and any oil vapors. Right there on the road. My, we've come a long way.

Wow, this really got ugly.

 

 

I guess it depends on who at the dealer told you this about the warranty, but i'd move along to a different dealer if that was their stance. 

 

 

Side note, it's about 5 minutes to put back to stock.

 

People have shown their results are positive in catching the oil. You either want it or you don't, don't see why the need for 2 pages of warranty arguments.

Think I posted this earlier. If you have oil in the line TO the manifold, you need a can. If not, you don't need a can. I believe I even posted the can supplier that gives that instruction on their website. 

 

Okay so let's assume you need one. Fine. As mentioned several times by others it isn't hard to remove and replace with the quick connects supplied by better suppliers. Okay  you just lost your warranty reason to not use one. Why argue about something that doesn't matter? Quit being lazy and take care of business. 

 

Next....who owns your truck? If you do and you are the one that will paying the cleaning bills later why are you letting GM act as if they own the truck? 

 

IF you lease  and they actually own the truck.....who cares....let it crater if their not going to take care of their own equipment. 

 

I never ever lease, and as I buy, I take ownership from day one. I could care less about the warranty. Outside verified callbacks a dealer NEVER sees this truck...EVER. I'm not going to have an argument with a service writer over how many lifters to replace and I'm not going to let the fools the built it rebuild in the same half a$$ed count the beans twice manor. 

 

I do not believe in letting the rat guard the cheese.

Until someone challenges them in court, they'd lose that one big time. It's a direct violation of federal law.

Actually emission code is a Federal law, unfortunately modifying / removing / tampering with is an automatic warranty void. 

The MMWA doesn't protect a buyer from tampering with a Federally mandated system. 

 

The consumer would be responsible for all court fee's and then repairs (if any needed) to fix the system and or engine problems.  

 

Most dealer's are not going to challenge you on this or deny a claim due to having a CC.


 

 

If you really want to get technical DOT can pull you over and do an inspection while also ticketing you for tampering with the system and driving on federal road.

 

But it's your 45-60k truck, do what you want lol. 

 

 

@Grumpy Bear you would be suprised what the T1 pcm's will tell a dealer now.  They knew I had changed out my tag lights to LED's due to the pcm throwing an internal code for a voltage fluctuation.

Luckily my dealer service manager is a friend and let me see what was going on.  It might not be throwing a CEL on the dash, but when GM plugs in, they know a lot more than people think. 

 

I work for Subaru of America,  and our engineer's have to go out to dealers all the time and plug into Wrx's  / Sti's to verify warranty claims on blown engines.

You get there and they look completely stock,  Some people even go as far as repainting the bolt heads to make it seem they have never been broken loose. As soon as the engineer's plug into the pcm, they can tell if the engine has had modifications, even as something as small as a high flow filter increases air flow against the maf which the pcm flags and saves for a period of time. 

 

Now are they gonna void a warranty for a K&N filter per say, no.     But when they install tuners to the pcm (marry them), it flags the point adjustments we're made to the software and that's how they determine who's fibbing lol. 

 

 

 

And for the record, I have a CC on my 2019 LT 5.3.    Sooooooooooooooo Bleh!

    • SPECULATION on the wars effect raised prices. AI is maximizing the profit. Refining is vertically integrated. 
    • It's the Middle East conflict that raised prices, not AI. But nice distraction.
    • Lauren Fix Is AI quietly deciding what you pay at the gas pump? How the algorithm picks drivers' pockets.   Every time tensions flare somewhere in the world, gasoline prices seem to jump overnight. Drivers expect it. The news blames geopolitics, oil traders blame uncertainty, and politicians blame each other. But here's the question almost nobody is asking: If computers can raise prices within hours, why do they suddenly become so patient when it's time to lower them? Americans have lived with this frustration for decades. The price of crude oil climbs, and gas stations respond almost immediately. Crude oil falls sharply, and suddenly we're told to be patient. Refiners need time. Distributors need time. Retailers need time. Somehow, that urgency only seems to work in one direction. Regulators have already gone after algorithmic pricing in apartment rentals, and they're looking at hotel rooms, airline tickets, and online retail. Now a new California lawsuit and a federal push to investigate gasoline pricing suggest there may be another piece of the story that deserves far more attention. It isn't simply about oil markets anymore. It's about artificial intelligence, algorithms, and whether software designed to maximize profits is quietly changing how fuel prices are set across America.   If that sounds like something out of a science fiction movie, think again. Kalibrating the market? Kalibrate is a real pricing platform. The company markets its software as an advanced pricing solution that analyzes competitor prices, wholesale costs, local demand, traffic patterns, and countless other variables before recommending the "optimal" price at the pump. By the company's own marketing, it serves many of America's largest fuel retailers and convenience store chains. Retailers use it because it promises to increase profit margins while staying competitive. There is nothing inherently illegal about any of this. Every major industry now runs on data analytics. The concern begins when pricing software stops simply reacting to the market and starts shaping it. On June 22, three California drivers filed a federal class-action lawsuit in Sacramento — and they didn't just sue the software company. They sued the gas stations. Kalibrate is the lead defendant, but so are Marathon, BP, Circle K, 7-Eleven, Speedway, Walmart, Sam's Club, and Albertsons. According to the complaint, Marathon alone runs more than 1,000 ARCO stations in California and has been letting Kalibrate set prices at them since 2020. Circle K, plaintiffs claim, has more than 400 stations on the software. Albertsons, they allege, has been using it since at least 2009. The complaint alleges that Kalibrate allowed competing retailers to share competitively sensitive information and receive pricing recommendations that discouraged aggressive competition. It describes a "restoration" feature that plaintiffs say lets nearly all the stations in a market raise prices at the same time. It also quotes Kalibrate's marketing, which according to the complaint tells operators that even in the face of "falling oil prices ... it's critical to avoid a race to the bottom," and warns that cutting your price to win customers "could be making a change that triggers a downward spiral." The plaintiffs call the platform the "central nervous system for a conspiracy to extinguish retail price competition among gas stations." Price pumping What does that cost you? Research cited in the complaint found that stations switching to this kind of software raise prices by about 6 cents a gallon on average — and by as much as 30 cents where most of the stations in an area are running it. Plaintiffs point to a real-world example too: They allege that when one California Albertsons turned Kalibrate on, its pump price climbed 3 to 4 cents within days. That sounds small. It isn't. By the complaint's math, a single penny on the statewide average drains $134 million a year from California drivers' wallets. Kalibrate says it disagrees with the allegations, calls its technology lawful, and intends to defend itself. The retail chains have not yet answered the complaint. No court has ruled on any of it. But what happens when thousands of competing businesses begin relying on the same algorithm to determine prices? Price fixing has been illegal in California for more than a century, and the plaintiffs are suing under that old law. What's new is a statute that took effect on January 1 — AB 325, the Preventing Algorithmic Collusion Act — which says plainly that you cannot escape a price-fixing charge by routing the conspiracy through software. Using pricing software is still perfectly legal, but using it to coordinate with your competitors is not. AB 325 makes it unlawful to use or distribute a "common pricing algorithm" — software that uses competitor data to recommend, align, or stabilize prices — as part of an agreement to restrain trade. Whatever you think of Sacramento, it closed that loophole first, and this case is the first real test of it. The A-word Washington is applying pressure of its own — though it is worth being precise about what kind. On July 3, the Department of Justice and the Federal Trade Commission sent every state attorney general a letter urging them to investigate whether antitrust violations or price gouging are keeping gas prices artificially high. "Recent volatility in crude oil prices does not suspend either the antitrust laws or state consumer protection laws," they wrote, "and it does not authorize companies to manipulate retail prices or collude with their competitors." The letter followed President Trump's complaint, posted to Truth Social on June 23, that falling crude prices weren't reaching drivers. But read that letter closely and you'll notice something. It never mentions algorithms. Not once. The federal government is going after gas prices with the same tools it has always used, while the argument about the software is being made by three drivers and their lawyers in a Sacramento courtroom. Nobody in Washington has said the word yet. And whether any of these investigations turns up illegal conduct remains to be seen. Anyone who has driven for more than a few years knows the pattern. Prices spike within days of a geopolitical event, then drift down at a painfully slow pace. Economists even have a name for it: the "rockets and feathers" effect, and they have studied it for decades. Researchers point to several reasons, including inventory replacement costs, consumer behavior, and local competition. None of those explanations necessarily involve illegal activity.   Dirty work   But artificial intelligence introduces an entirely new variable. Unlike traditional pricing models, today's software can monitor competitors continuously, process enormous amounts of market data instantly, and recommend price changes faster than any human pricing manager ever could. If dozens or even hundreds of competing retailers rely on similar recommendations generated from comparable market data, the practical result may be less price competition — without anyone ever picking up the phone to coordinate prices. That possibility isn't unique to gasoline. Regulators have already gone after algorithmic pricing in apartment rentals, and they're looking at hotel rooms, airline tickets, and online retail. The Justice Department sued RealPage over the software landlords used to set rents and settled the case last November. The concern in every case is the same: that algorithms may accomplish indirectly what competitors have long been prohibited from doing directly. It's worth being precise about what that settlement did and didn't say. RealPage paid no penalty, and the government made no finding that it broke the law. What the DOJ objected to was the use of nonpublic information from competing landlords — not the software itself. Using an algorithm to price your product isn't illegal. Feeding it your competitors' private numbers is where the trouble starts. That distinction is going to decide the gas station case too. Technology moves faster than regulation. Thin margins This debate also exposes another misconception. When Americans get angry about gas prices, they aim that anger at the oil companies. In reality, what you pay at the pump includes crude oil costs, refining expenses, transportation, taxes, distribution, and retail pricing. Gas stations generally operate on thin per-gallon margins — the National Association of Convenience Stores puts the net at roughly a dime a gallon once credit card fees and operating costs come out — while state taxes and regulatory costs can dramatically affect what you pay locally, particularly in a state like California. If gasoline prices are rising because of global supply disruptions, consumers may not like it, but they can understand it. Markets move. Wars affect energy. Hurricanes interrupt refining. But if pricing software is reducing competition by encouraging retailers to move together instead of competing aggressively for customers, consumers deserve answers. Artificial intelligence is quietly becoming the invisible middleman in countless financial decisions Americans make every day — insurance rates, airline tickets, hotel rooms, online prices, and now what you pay every time you pull up to the pump. Most consumers never know an algorithm was involved; they simply assume that's what the market decided. Algorithms don't care whether you're commuting to work, driving your kids to school, or trying to keep your small business afloat. They don't understand household budgets or family vacations. They optimize. That's what they were built to do. The question was never whether artificial intelligence can set prices more efficiently. It's whether we've quietly allowed machines to redefine what competition means. Because if software can determine the price of something as essential as gasoline today, what will it be deciding tomorrow?   https://www.theblaze.com/lifestyle/is-ai-quietly-deciding-what-you-pay-at-the-gas-pump  
    • All valid.   But.  How many people really do this?  Its few and far between.  Most just drop it into D and go.  
    • Did you do this after the warranty expired? Or still under warranty? I am guessing the warranty would be void.  I am trying to find a happy middle ground on this by perhaps keeping the cat but removing everything else.
