Thé post where I got this questionned thé relation with 2017 2018 and some 2019 problems… I was searching for a thinking answer and not cockfight with the one who wanna absolutly be right… there is a fact … all the rest is supposition…that was an interesting thing to debate …and it appears clearly that some need to be more humbles

There's no data to back up your suspicion that there's a problem with 2019+

Is there a preferred chain tensioner you can point me too?

Katech says they have tested all the pumps and '19+ are stronger but still break

As I stated before, no offense to Katech but they are in the business of selling parts. The failure rate data doesn't suggest that there's an issue with the 2019+. I have no doubt their billet pump is stronger, but is it needed? That's debatable. I'd say if you're doing a whole engine build, sure might as well do it if its within budget, but it's certainly not a necessity for anyone that's stock or even full bolt-ons.

I get what you are saying, but Chevrolet is in the business of selling cars and weaseling out of warranty claims and recalls.

I agree that the failure rates for 2019+ are very low, and probably statistically minimal, but it's still important to see these failures on the forum and to discuss.

I'm very glad I have a Katech pump in my 2018.

Katech says a lot of stuff, and they need to sell their products. Of course they're going to talk any competitor's parts down. Just take what they say with a grain of salt when it comes to this stuff.

Katech was asked by members of this forum to come up with a stronger replacement for this shitty oil pump, and they did. They have tested, and broken, all 7 GM versions of this pump, and were able to make them all fail, though they did say that the later versions were stronger than the earlier versions.

Everyone on the planet needs to sell their products, or their services, or their labor. Just because they do that, does not make them suspicious.

Katech has done Camaro owners a great favor by building a strong and reliable replacement for the piece of shit that GM installed in these engines. I think we should be thankful they came up with a viable solution, rather than put them down for wanting to sell a product.

At least we have an alternative to putting another garbage GM pump in our engines.

If you have a 2018, I don't blame you, it's good peace of mind.

The chances of a pump failure are very remote. Surely all of us don't have to run out and buy new pumps.

Thats right. Look at the main oil pump failure thread poll numbers. The overwhelming majority are 2017 and 2018 cars.

I am a huge skeptic... like you it appears.
I see a MAJOR benefit to aftermarket companies who are not only identifying areas for improvement from cars / trucks from top to bottom through a lens of performance... but through a lens of durability.

The big automakers are working on tight margins, and severe competition.
We all know Chevy has the tools, team and technology to build a world class... super durable machine... thats not the issue.

IMO, The issue is when you try to make a world class track pounding competitor for $75k. You need to cut costs to get there, and having driven alot of higher end performance cars, it's not hard to see where chevy cut costs... and I'm glad they did to an extent... otherwise I may have been priced out of a ZL1.

Companies like Katech, Weapon X, DSX, Kong, Synergy, BMR, BTR, LME, LMR, Lingenfelter, Rotofab, DMS... just to name a few...

Are going us a HUGE FAVOR but answering the voices and requests of us owners. I sure as hell dont have the tools, team and technology to create a more reliable oil pump, or VVT delete kit, low pressure fuel AUX kit, E85 kit, better HX, more aggressive cams, more durable lifters or valve seals, less restrictive intakes or large TB's, better sounding exhaust, brighter LED side marker lights, lighter wheels, less flexible suspension parts... just to name a few.

Those people and products are in the business of making money just like mine. They are answering the calls, and providing a unique product that meets our needs for performance, durability, looks or a combination of the three in order to be relevant. YES they have to make money, that is their purpose... and they cant do that if they are unable to meet or exceed the engineering done to the products that rolled out of the factory.

Sorry for the rant.
Im out

This one? That's a hefty investment, but are you saying that these stock have had failures? Are you adding this to the list of "no brainer" upgrades while the engine is apart?

To address above comments above, our job as a top tier, reputable performance shop is to provide accurate and honest data. There is not a single Katech product that we sell that is not produced from data driven development.

You have every right to believe what you want, and we will always respect your opinion. Regardless of opinions, our data shows that GM has not resolved the oil pump issue. They have made improvements and revisions, but they have not completed fixed the issue with the internal slider breaking.

If you believe the newer pumps are fixed, you can run them at your own risk, nothing is stopping you. If you decide to buy a Katech pump, we can guarantee you will never see cracked internals from our pump.

The frequency of breakage from the newer pumps is less, both from our data and driven car data, but less is still not zero.
