I'd like to see some boroscope pics of 60k VR30's with and without catchcans.

So basically for daily driven VR30s it’s safe to follow periodic cleaning (? walnut blasting what I went through with my previous E46 M3) north of 50K miles, and yes always with quality gasoline.

I’m more concerned with track use, though, high temps, high cornering Gs, frequent redlines etc. The Cayman has upgraded UAOS catch can and I dump 2-3 oz of oil after each track day.

For now will leave as-is OEM since under warranty and only part time tracking coming up. Will address braking and cooling mods first.

I can't speak for every manufacturer, but I am fully versed in what Dodge, Chevrolet, and Ford have been doing with catch cans. In rare occasion, cars like the GT500 CFTP comes with an oil separator from the factory. But, for those that do not, the OEMs have been cracking down on the use of them in regards to warranty claims. I've never had a warranty claim with this Nissan, so... my experience with them is nil.

For most minor warranty claims (ex. claims under $1,000), they don't argue warranty work unless there's obvious violations (tune, non-standard powertrain equipment, etc.). They'd rather pay out the small claim than pay $5,000+ for a lawyer to defend it in court. Where people are running into trouble is for things like catastrophic engine failures or some failure that resulted in a catastrophic loss of the vehicle. When you have a 5-figure repair bill, both the dealership and the OEM are going to do everything in their power to find ways to decline the warranty. If a person is on the level with a stock car, they're fine. But, when a person has some small amount of mods, they're going to try and link it to the issue.

A catch can is an interesting issue, as if it is working and is installed correctly, they don't do any harm. However, it is considered a modification to the emissions system, as the PCV is used predominantly to vent excess crankcase pressure and contaminated emissions through the system, on in to the engine and ultimately into the catalytic converter. Therefore, the catch can is a modification to the emissions system.

That modification is in violation of the Clean Air Act of 1975 and OEMs have been declining warranties with increasing frequency, citing "evidence of criminal tampering with the vehicle's emissions control system(s)." Thus, it end-rounds the Magnusson-Moss Act provisions that state that a part must be proven to contribute to a failure while denying a claim. In this case, they're stating that if a transmission fails, they could deny it due to the tampered exhaust which, being illegal, should render the vehicle not roadworthy and it was therefore being used against the terms of the warranty agreement. Therefore, a catch can is becoming a way for OEMs to patently deny anything they want.

Now, there's plenty of legal means of recourse. They're simply banking on the fact that it takes 2+ years and tens of thousands of dollars to bring a case against an OEM and without the Magnusson-Moss Act defense, plaintiffs are going to have to expend a lot of money just to get to trial and be forced to try and defend that what they did wasn't illegal and be without said car for 1-2 years on average.

So, this is definitely becoming a thing.

I know Ford doesn't have any problems with catch cans as they offer them as "Branded" upgrades for various vehicles: Darkhorse, Mustang Gt, Bronco and F150. I have had all but the Darkhorse and mostly had the Ford Racing catch can as they look factory and work great. Only time I swapped from Ford Racing to Custom or another brand was when going FI.

I also know that it doesn't cost nearly as much to fight any claim if done correctly and it rarely ever goes to court. You want a lawyer that deals primarily with auto manufacturers.

The only time I had to deal with a lawyer and a manufacturer was with Nissan. The dealers are mostly the ones that try to void warranties for aftermarket parts. You would be surprised at what a manufacturer will give you rather than go to court, if your case is sound.

Manufactures like Ford list it for competition and off highway use.

I have always used them for race and street vehicles, and they have all been beneficial.

To the OP and others, I aways say if you are worried about warranty then you probably shouldn't do certain mods if you question them. Going to be hard to fight if you question it yourself.

A proper catch can if installed properly will not damage an engine. Do you need it, NOPE!
Me personally I would add it to any vehicle I definitely plan on taking to a track.

I refuse to get one until the warranty is done.

Catch cans are for YouTube content. If they worked, manufacturers would have them pre installed. These catch can people need to get a life.

LOL. Since I can’t take my Z with me when I’m 6 feet under, I’m not too worried, either, at the rate I’m putting on the miles.

Well, I've seen much worse things that were debatable about "working" or "effectiveness" be forced onto..... "Evidence or research SUGGESTS.......blah blah blah, just tell your doctor to prescribe it to you, no we won't be guaranteeing it's effectiveness in writing, we just suggest" And people will gladly experiment with their own health using new, barely tested ideas (GLP comes to mind).

I used to be an ASE technician. I see some value in catch can, not enough to suggest it to others. Definitely wouldn't tell someone to "get a life" over it, that's a rude, dismissive statement.

I'm surprised, with your all-knowing expertise, you missed the couple suggestions to "use high quality gas". Surely you think they need to "get a life" too? Or do you actually believe that the gas in your fuel system ever reaches the backside of the intake valves?

I run 95 octane.

If you think I was being rude, you must live in California.

Catch cans are about as trendy as boot cut jeans.

Take your sensitive skin off and be a man already.

I'm not sensitive, I just see someone saying messed up things to fellow Z enthusiasts. Telling someone to "get a life" over mods is pretty callous.

And octane level has nothing to do with my point about "quality" fuel, also shows how little you know about these concepts, which is why I make a point to call out your "get a life" statement to fellow enthusiasts.

I just see an ignorant person flapping their fingers on the Internet about something they know very little about.

Again, to be clear, I am not defending catch can. I think the premise of just driving the car and enjoying it for what it is correct.
But, I also feel the same way about certain mods people do to their vehicles, and I don't go dissing the concept of an individual wanting to do mods I personally wouldn't do.

I like your comment how you used to be an ASE tech. There's a reason you're not anymore.

You asked about fuel so I told you so I don't know why you would defend yourself over my comment.

You got to be some bored husband that hates his wife to be on this forum and defend yourself.

And I'm pretty sure you don't know what the word ignorant means because if you did, you wouldn't take offense to anything I said
