This was probably the best guide out of them all on KZfaq, thanks for helping me with my VN!

Any modified performance car that you see will have some sort of oil catch can on them. Oil Catch cans are placed by the car owners themselves which beg the question of why do the car manufacturers choose not to place an oil catch can in the vehicles. Any GDI Engines benefits greatly from Oil Catch Can let alone a performance vehicle. If you understand the purpose of a catch can you can say there is a good argument for automakers to place catch cans in their engines no matter if it is a performance vehicle or not. As PCV systems suck the pressure out of the crankcase, it also draws out a fine mist of oil which is then included in the air/fuel intake charge. Although you might not notice any performance loss in a stock engine, the blow-by created by GDI Engines can lead to reduced combustion, fouled spark plugs, detonation, a dirty throttle body/intake manifold, and it can even lower the fuel efficiency. This type of damage over time with blow-by will cost you thousands of dollars in repair cost. There are auto manufacturers that provide products to address the blow-by problem. This is usually still considered an aftermarket product and done under a different name or within the "performance" division. Vehicles owners still mismanage regular oil changes. It may not be you the reader but let's face it consumers of vehicles do have a problem remembering that vehicles need attention and maintenance. Adding another "chore" for vehicle owners is just another maintenance concern for a vehicle owner to add to the list. And to the main reason (personal opinion only), even though auto manufacturers know that there is a blow-by problem with modern engines that does not mean they want or will run out to fix it. Remember blow-by damage is done over time. It is not something that shows immediately. An auto manufacturer does not want you to purchase a vehicle and keep it for the lifetime of the car. They want you to buy more cars from them. An Oil Catch Can not only helps with the longevity of your engine but it also helps in performance. So the question is if you spent forty thousand dollars on a vehicle how much is it worth to spend to maintain performance of that vehicle.?

I added a custom Saikou-Michi can on my Veloster N. It is installed the intake (PVC) side. I also installed an oil separator on the turbo-side. After a year turbo-side had nothing so I removed it. I did run a line from the bottom of my can to the engine under cover so that I can drain it when I change my oil. Absolute must-have on these GDI N engines.

Want to note that the torque spec on that bolt is around 40 ft lb for those that are looking in the video for that information. It's towards the end of the video. Okay so I've been checking the dipstick on mine and it's been very low. I decided to take the catch can off for the winter time and in doing so I unscrewed it and see how much oil was in there. I would say there was only about a teaspoon of oil in my catch can. This is after roughly 4,500 mi. Also I guess I didn't see it but the catch can itself was rubbing on the black bracket next to the motor. So when you do install keep an eye on the can where it's located at. Having that rubbing up against that mount could cause false knock which will retard the timing and cause lower power. I also have read from "Rori" whose brother does KZfaq content on his Elantra N that he tracks, that the cylinder head on these cars have a " built-in catch can" and that an oil catch can't really isn't needed for these cars. *Shrug* I personally have never taken off the intake manifold to see where that oil drains to from that crankcase port.

This was a very good video, your work is appreciated. I am surprised your kit didn't come with check valves to use inline with the hoses; that seems to be standard now for ADD W1 v3 and v3.3 catch cans for the Elantra N.

My mechanic didn’t hook mine up to the pvc. He used the cold air intake hook up , and the top valve closer to the cold air

I decided to use a different return line. I noticed the one that comes with the kit is really flimsy. Also I used a 90 degree 3/4 fitting vs the 1/2. I think the 1/2 is too small. But great video.

can you provide the link in the description. of the product

This may be a dumb question, but im still asking. If you install the catch can, has anyone had the dealership reject any warranty work? I know the catch can is better for the engine, but i also know dealerships are happy to find reasons to end your warranty.

PCV not pvc. Big difference. PCV = Positive Crankcase Ventilation. PVC = white plumbing pipe

Nice work. looks sharp. How is it working so far? Any issues in cold weather?

How easy is it to unscrew the can to empty it? Can you reach under and get it out without having to take anything apart? I’ve always had this question especially with dual catch can setups on things like a Subaru WRX STi. I really like how this one looks, really clean install.

I noticed that doesn't come with a one way inline check valve that other versions do. Any thoughts on that?

Great diy bro, definitely gonna come back to this when i get my catch can for my veloster n 22'. Do u have a ig i can fallow you on?

I assume you run the can year round? Have you ever had issues with the lines freezing in winter?

How are you, I've got a black Elantra N 2023, I'd like to know what your thoughts are now after having it installed for a while. Is it actually worth it?

How much have you caught? Would you say it's worth buying after changing the catch can out a couple times?

Thank you for sharing

what the difference between this catch can and the one from boomba and SXTH

Hmm was that supposed to go on you're engine mount? The aluminum from that bracket is probably nowhere near as hard as ur engine mount.. I thought it was supposed to be mounted to the bottom bolt on your coolant reservoir?

Please do not shoot the messenger when I ask, even though you paid off your car, by installing this can it potentially void the warranty?

Hello, what diameter do i need to buy the hose for the pcv valve? Thanks!

nice guide.. can u tell me if this is the universal V3 or the Elantra specific V3, cause I want the mounting bracket n I'm not sure which version has it, or did u buy the bracket separately?

Is there any restriction with this catch can?

Where is the check valve

Where did you get the catchcan from and how much?

What oil catch can you uaing

kzfaq.info/get/bejne/ipNyZ7mD3afYkqs.html Not a direct link but this video @2:49 details a study published in The Society of Automotive Engineers on the benefits of Catch Cans! I am sure with some Google Fu you can find the study.

How come you didn’t use a check valve?

this is great and all, but the car has a 10 year 100k mile drivetrain warranty. I could care less about carbon build up tbh. Unless you already voided warranty with parts

PCV********

Absolute waste of money and time. If so “vital” the manufacturer whom must warranty the engine would have surely included a $10. Miracle add on component to ensure engine performs or runs longer. Have never read any empirical data from two identical engines one with coffee can installed and one with out comparing enternals after say 50,000 miles. If you can point us to any studies or anything showing the real world benefit, other to the company making them, we would surely appreciate it as I’ve never found any.
