Engine Catch can

I agree about the Boomba Catch Can placement. In very cold climates during winter months I would be worried about contents freezing if there is significant captured water vapor.
What are you exactly referring to here? I understand that you already have a catch can and you are just searching for an appropriate bracket? Are you looking for lines as well? Or did you purchase a catch can kit with no bracket??
The only relevant information I can attempt to provide is that the Mishimoto kit came with a double barbed metal fitting that you attach to the OEM hose that runs to the IM. You attach the other end of the barb to the line that was provided by Mishimoto to the catch can outlet side (1/2in ~ 12.7mm). The inlet side of the can is attached from the catch can to the PCV via a smaller line that was also provided by Mishimoto (3/8in ~ 9.5mm). No cutting of OEM hoses needed to install Catch Can. It was super easy and took me like 30 min.

Anyone have any boroscoped intake valves at 10k miles or higher? Looking to boroscope my own valves soon and pull the plugs and examine the tops of my pistons as well. Looking at the tops of the pistons is easy enough but the intake manifold is difficult to navigate without a super expensive articulate boroscope. Anybody have any suggestions on a semi expensive boroscope that is capable? I would love to pull the whole intake manifold but I definitely do not have the free time lol.
Cool - see my post

In post #48 someone said it’s 14.5mm ID not 12.7mm ID. So I’m totally confused. Also it seems hard to get to as it’s buried away - I don’t wanna pull anything off to get to it or cut the OEM hose.
You're either going to have to cut the primary PCV hose or move the intake manifold out of the way to get to the PCV tubing. The tubing from the to the valve cover to the CC is not the issue. I'll have to look and measure the primary PCV hose.
It's just something additional that has to deal with when utilizing one in northern tier colder winter climates. Worrying is simply a useless emotion.
As long as the CC is situated in the engine compartment with a short run of hose, it's the best anyone can do. Residual heat from the engine compartment will aid in keep it free from freezing overnight. Any longer then then overnight, doesn't make any difference. If it's going to freeze up. It will certainly happen over a couple of nights, without running the engine at normal temperatures.
The idea is to keep the CC warm during operation and out of the the inflowing engine compartment air. This is specifically why the SXTH Element CC system and others similar to it, that are place in the front of the lower wheel wells, are a no go!
The same can happen with where you mounted the catch can. Especially overnight a couple of night sitting outside or in a garage in freezing weather, without running the engine up to operating temps.

Ahhh I see what you are saying now. Did not mean to confuse you. Yes the actual size of the OEM pcv hose where it attaches to the IM could be 14.5 mm. I have never measured it myself so I cannot confirm. When I went to install my can I also noticed that the connection to the IM was wayy deep down there and I did not want to mess with it or cut the OEM hose in case the car ever needed to be warrantied . So I just used the adapter that came with the Mishimoto kit. I never removed the OEM pcv hose (14.5mm) from the IM. I simply took the end of the OEM pcv hose (9.5mm) that was attached to the valve cover and attached it to the double barbed metal fitting that came with the Mishimoto kit. Then you run a (12.7mm) tube that was included with the Mishimoto kit from the other side of the barbed connector to their catch can. So to answer your question your best bet, if you do not want to cut, may be to get a double barbed connection piece that attaches to the end of the OEM pcv hose (9.5mm) then run another line from there. See pictures below for Mishimoto kit , their double barbed metal connector, and how my OEM pcv hose is still attached to my intake manifold . It is highlighted with a circle .

I edited my post some to make it more clear . See previous post.

Do you reckon it will be sufficiently warm installed in the location as per the pic?
oooo, I like that, had JBR stuff before and its quality stuff.
$260 = £200 delivered to UK + import tax b/s = £250-260 all in.
Thats pretty good!
Yes, there's a bit of a pocket in that location out of the direct air intake inflow.
Doesn't matter, the pressure generated from the crankcase pulses, will be sufficient to move the vapor to the can. Keeping in mind this is a "vapor" of combined composition; oil/fuel/water.

Posting for a friend...for your info. He’s got a really nice PW i30N, just done 6500km.
1000km with the Mishi catch can, 60% city with a reasonable amount of fun times on the throttle. About 1.5mL tops - nice clean dark golden brown oil. He’s going to stuff the can with proper stainless steel scourer for the next 1000km and see what happens then.

HI. I am new with the i30n since 3 weeks ago. I have Reed all posts and I have a question (maybe somebody explained it but I haven't seen it). Has anyone thought about expelling the vapor that is not left in the tank, to the air? And in the pcv return, put a cap.
