Does a catch can and separator have warranty implications ? Anyone have a dealer use it to deny warranty coverage ?

Apparently, yes.


I would suggest you google the question, and a bunch of threads on this forum will pop-up.

I installed a Catch Can on my 2015 C7 Z51 at the 280 mile point. Since then I have had several dealership oil changes, and two recalls, and have never had any warranty issues because of its use or installation. Installed and used properly all the Catch Can does is catch excess oil mist and condensed fuel vapors allowing cleaner gases to passed on to the intake. Assuming the Can is emptied periodically I can't imagine why a dealership would use a Catch Can as a reason to deny warranty work.

One guy on a Camaro forum last year. Draw your own conclusions

Had one on all my Vettes's this makes 6....each time I asked the dealership that I regretfully have to give this car back from time to time and the response has been unless it contributes to a failure in any way, not a problem with them ...fairly passive if done right no chance of loosing oil ect...the cow has already left the barn at that point...in the end you decide but I would ask ...not all will have the same approach.

This may or may not be a picture of my car with what appears to be a catch can that may or may not be present if warranty work is needed.

if your engine blows up or has an issue just remove it prior to taking it in.

After reading tadge's comments and considering the de-carbonizing options available, I'll keep it stock.

When I went in for an oil change last year, the Corvette specialist said, "good to see you installed a catch can" and then brought over a coked up valve from a DI engine and said that, "you don't want to end up with this problem".
I also installed one on my GMC 2015 Sierra with the 6.2. This is a different dealer, and they have never said anything about the catch can at the free oil changes. I have 18k miles on it and am surprised at what I empty from it on a regular basis.

I rather be safe than sorry that is why I remove my CC before bringing mine into a dealer.

It's easy to remove and it's not worth a risk of having the warranty voided.

Proceed at your own risk.

My beautiful daughter married a wonderful gentleman that ownes a Chevy dealership in south TX. Not too worried about my RX Performance catch can or anything else. My service work comes at a really good price.... Catch can, CAI, other stuff goes unreported.....YEA....Life is Great!

but based on the cost of the wedding......the next few 'vettes I get at his cost, will probably not make me even.......LOL

​​​​​​​but the wife & daughter are happy....HA!

While on this subject, can someone post a part number for the pigtail with the quick-connectors on both ends the connects the crank to the intake? I'm talking about the stock "tube" you remove to connect the catch can. If not a part number, at least tell me what it's called? thanks

Dealers don't make warranty decisions, GM does.

There's no logical reason that a dealer, as an independent business, would ever care about a modification until GM starts asking questions once a major malfunction has occurred, and then refuses to authorize reimbursement to that dealer for a repair.

At that point, they care a lot.

Again, why take the risk simply uninstall the CC before bringing the car in for service.

Had one on my 3 1/2 year old Z51. Removed before I sold it and will install on my Grand Sport on order. I will install just in the existing PCV line (not drill a hole in the air intake tube and use two outlets.) For the driving I do that is sufficient to accomplish 95% of the benefit, IMO.

It adds not significant flow restriction and simply catches and condenses vapors from the crackcase that would go to the intake manifold and bake on ("coke") the back of the intake valves.

I do empty it every few thousand miles and never have more than a few ounces of "stuff" collected. I'd be happy to defend the addition if there was a warranty issue.

If installed improperly (a possibility if you have two can exits and the check valve is not installed properly) or if it wasn't emptied that could be an issue. With a single outlet there is no need for a check valve as there is none in the PCV hose that it replaces.

My opinion FWIW, the OP's choice.

- I would also like to order these to have them on hand in case I have to do a quick removal...

Anyone planning to remove a catch can to avoid warranty problems will need to keep any needed tools and parts in the car because the kind of engine failure that would lead to a catch can warranty issue is likely to be the kind that leaves the driver stranded on the side of the road.

Maxie2U

All it takes is one little wrench and the OEM hose. I carry both in the little storage bin in the hatch area. Takes less than ten mins to convert back to stock even stranded by the side of the road.

See, simply.

Good job Maxie! You are prepared as others should be also.
