I'm on my 4th vette and know alittle about this and that but not about a catch can. The car is a 98 with 189k and mainly all stock and will mainly stay that way other than a cold air but can y'all educate me more on a catch can? The prices seem reasonable and quick to install but i don't know alot about them. Everything I read is "pro" and no cons, so that's why I thought I'd ask

at 189k miles probably won’t matter much at this point. If you decide to pull the intake and heads and clean things up, id install a can then.
I once asked Evil-Twin about catch cans in a private message back in 2008 and he responded back to me with this

I don’t post in open forum anymore because the forum has slipped so far down the Do it yourself ladder, that I would be battling all day...

This kept the cast down.. when we stared this car we had a budget and a target market . its a credit to the design engineers for making this car and the project managers for keeping it in budget.. designing a front suspension that would carry the extra weight of a super charger and inter cooler would have added weight and cost... I was personally turned down for a mod that would cost 70 cent to each C5, I Have 7 designs in every C5 on the planet, and one of them would have cost and extra 70 cents a car, but it was over our budget so I got a no... this is typical of every project of the C5 platform.. Some of the components are cheap, but thank god they are because if we made every component as good as we could very few people would be able to afford this car... I see people bitching about poor design all the time.. it just goes to show that no one knows what it takes to deliver a car within budget.

No offense to Bill, but this was my “catch” after 53 miles of driving. This should not be fed back into an intake manifold. Imagine what a 100k mile car looks like. I don’t think the c5 designers ever really figured out the pcv system on these cars just from the mere fact there was about 5 different design changes.

RIP Bill
Your friend, Mike
Great info Mike...thanks for posting...he is still giving help from the grave ...RIP Billy Boy
I did not see eye to eye with Bill on a lot of things but Bill was a genius when it came to cars. He really knew the C5 Corvette. I have had arguments with Bill but respected him whether I thought he was right or wrong, usually right when it came to engineering. Ed aka as Patches was another great engineering mind.

Rip billy. But Billy always argued with everyone on this forum. Once, he was arguing with me via text message on the fitment of baer brakes saying they wouldn’t fit my car. Billy didn’t know I was literally standing in baer brakes in Phx and they were reading his texts and disagreeing with him. Baer knows their parts better than Billy. He was such a character. Rip Billy aka EVIL TWIN.
I did install an Elite Catch Can on my '99 despite Bill's recommendation. Had it on my '99 for 8 years and sold the car with it. I checked it often and never collected any significant amount of oil. I emptied it twice, the second time was just before the new owner took ownership. I could have sopped it up with a section of Bounty. My engine was stock with Kooks long tube headers Magnaflow exhaust Blackwing (oiled filter which was another of Bill's pet peeves), never traced or drag raced the car. Modified LS engines benefit from catch cans. I liked the quality and look of the Elite Engineering product. They made some nice products.

Sounds like you had it installed incorrectly. Elite is fine. But on the cheaper side. No engine builders use elite. It’s like an eBay product.
I had it installed correctly but thanks for your presumption.
I don't wind out each shift at red line but drive like a responsible adult in my daily commute. If I did drive like that for 10-11K miles per year I could see having to empty a catch can frequently especially on a modified engine.

^^ this right here's what i was about to say.
the effectiveness & benefits of a catch can it all depend on how the car's driven. a stock car that's driven with civility all the time will be wasting money. i've got a big cam & big blower that, when driven smoothly around town & not wound out, collects very little oil... but a weekend at a road course could easily collect a few ounces.

Since when is driving like a “responsible adult” mean you shift like a grandma!

Bill and Ed were 2 of the greatest and most helpful assets on this forum...Ed is still alive... Ed had the greatest write-up and pics that I have ever seen...
why for? i've had my catch can on for over a decade (8yrs of which was with a blower on a stock engine - the rest with a built top end), and almost 40,000 miles of driving across the country or just putting around town - mostly in vacuum - have resulted in oil changes that only condensed a few mL of oil into the can... because
checking the can after a track weekend (or a few "energetic" drives through the local mountains), however, has resulted in ounces of oil in the can.
Ah, the great catch can debate. A MUST for every automotive forum. Entertaining and yet informative. My own personal experience is it's darn near a necessity on today's direct injection cars, definitely needed for a track vehicle and probably a "hey why not?" for a street performance car. I've got one on my C5 track car and I also get anywhere from 1 to 2 ounces of oily substance after a track day. My can is from Mike Norris. Not sure if he's related to Chuck but it does kick ***!
My basically stock LS1 with 65k has a catch can, I empty it twice a year and it is a weekend car with no racing.
I originally added a catch can when I swapped my LS1 intake to an LS6. When I saw the amount of oil that was in the old LS1 intake, I decided a catch can will be added.
Last year when I cleaned my throttle body I took a peek inside the intake and it was clean.
Seeing is believing, I happy happy with my Moroso catch can
Benefits to catch can?
That's it exactly.
