Looking for some guidance on fitting a catch can. I’ve seen the available kits, but I’m sure there has been people who have fitted a universal can and their own lines for much cheaper. Can anyone weigh in?

What are your goals?

The cheapest option I've seen plumbs a rubber hose into the factory ccv hose and runs it to a universal can, but it doesn't do much. Our PCV systems run clean when it works, and a catch can itself won't prevent the pcv from failing.

I'm using a BMS oil catch can and it's working great. Fits perfect with a pure 800 / CTS intake setup. Can fills about 1/4 full per year.

I had the BMS catch can for years. With the 0w20 there was always fluid in there. Since switching to 5w40 there was almost never anything in there, maybe a few drops of fuel or water.

I switched to the Ross kit a little bit ago because why not and I was really surprised how much better the car ran. Third gear pulled way more agressively. The original PCV diaphragm was pretty much shot. I haven't got a single drop of anything in the catch can for months .. I probably don't need the can and should just vent it underneath the car.

I'm also using the ross racing kit and I think I'm using the v2 but so far with only running TU + DAW V2.5+ I had little to no condensation build up in the can for months. Now upgrading to a DS2 + DAW V2.5+ I do not believe I am building up any liquids in the can during the socal winters around LA county. Works really well but stinks from the outside

I have the Burger motorsports oil catch can (double baffle)
Easy install and easy to maintain.

Hi All,

I've been looking for an Oil Air separator System for awhile and couldn't find anything i like. I am always skeptical how well "baffles" can actually filter the blowby gases. So i decided to make my own kit using a Ryco RCC360 oil air separator. Ive always been using Provent 200. That to me is the industry standard. BUT the engine is way to tight to fit a provent 200. After quite a bit of googling i manage to find an alternative, Ryco RCC360. Functionally it is effectively the same as a Provent 200 but has a much friendlier form factor. It is taller but most importantly, slimmer.

Here are some pics:
