Davo01, There are two ways to install the catch can fitting from the PCV. You're going to have to loosen the intake manifold and drop it back to get at the entire fitting. Or you can just cut it off above the location where it juts out from between intake manifold and the head utilizing a barbed inline connector.I am somewhat surprised at my results - I do my fair share of 5km drives. However, those short trips are serial trips with short stops in between so the car never cools down between trips. If that makes sense lol. It’s sorta like a longer trip.
I am still thinking of a can (precautionary as per R VelosterN) and have one on order that I linked to here ages ago.
What I don’t get is how / why they join a 9mm barb and a 15mm barb *with a single hose* lol. That and how the frack I get that second clip off - it’s buried so deep.
This will probably my last post besides replying on this thread as I am pretty satisfied with the results I have gotten thus far with gauging how well the effects of a catch can work on these VN models. Information is very straight forward. My VN is now at almost 7K miles. I just did a DIY clear bra install and changed my oil at 6K miles. She is still running smoothly with no issues besides some possible gear grind and tough shifting under full throttle with gears 2 and 3. After changing my oil at 6K miles and capturing oil, the results were sent to Blackstone Labs for analysis. Everything checks out as normal and my fuel dilution was still less than <0.5%. I am now running Amsoil 0w-30 and this was my first oil analysis with Amsoil 0w-30. Blackstone stated that the viscosity is in the 5w/20 range. The captured oil also looked dark but still in pretty good shape. They recommended that I try extending my oil change intervals to 5K which is music to my ears. I also emptied my Mishimoto catch can and there was some apparent oil buildup around the outside of the micron filter (maybe will clean the filter soon?). The can contents were pretty consistent, still a lot of oil with what appeared to be a slightly higher amount of vapor as I am now driving in the winter months (more condensation of vapor because of the cold). I measured out the contents that were captured in the catch can to about 1 TBSP again so roughly 15ml. I also removed what I believe to be the pressure sensor for the intake manifold and temperature sensor for the intake manifold (somebody corrects me if I am wrong) in an attempt to use a boroscope to peak at the valves and noticed both sensors were coated in oil. I was also able to see very small puddles of oil within the intake manifold. Unfortunately with my cheap boroscope, I was not able to see the valves or turbine blades as I had planned. I will leave these images up to somebody else until I can get a more capable boroscope. I say all that to say that there is a good amount of oil vapor in these intake systems no matter which way you slice it. How you want to deal with it or ignore it is up to you. If you don't plan to keep the car past 60k miles you can prob. just ignore it. I plan to keep the car for life so I am being very careful with her besides the clutch dumpsI am confident that a catch can is a good tool to use with this system to help mitigate carbon buildup. Hopefully, we can get some pictures of some valves soon! I will be getting a more expensive boroscope earlier next year. Good luck everyone!

90 ml can https://www.mishimoto.com/hyundai-veloster-turbo-catch-can-2019.htmlCatch can has a 3 oz. capacity for longer servicing intervals
Is that the compact 90mL or the large 200mL Mishimoto catch can?
It's the compact 90ml can. Fits nicely and snug to the Coolant Reservoir mounting bolt that's closer to the turbo.

Too bad they don’t do a kit for the i30N.
Worst case I ask my brother-in-law (a mech engineer with a sweet home workshop) to fabricate a bespoke one with me if I stretch the relationship or I make a simple one like Tarmo has advised me off line![]()


The problem with mounting it on one point only is; eventually the bolt pressure and engine vibration on the plastic will crack the tab. Both bolt locations need to be mounted into place. With all the backwards and forwards movement from the engine, this movement is being transferred to the oil lines lines and on to the can itself.I only mounted it with one bolt. A little blue Loctite and it shouldn't move at all.

I seriously don't believe anyone is worried here. However, what's been observed and commented upon is a statement of fact. It's just a poor set up, based upon the information and photos you've provided. If it was designed for the Veloster Turbo, then it was designed for that application and not the VN and i30N.To each his own if others are worried

So it's reasonable to say, it won't work for the i30N or VN properly.
