I want to install a catch can on my Genesis because people have said its just a good thing to have. So I have some questions



1. Will one of those really cheap ebay catch cans work out ok, like this one

2. How hard are they to install? I tend to have a very amateur type of knowledge when it comes to working on cars so is this something even an idiot who doesnt know much be able to install it themselves?

3. If you need a catch can, how come Hyundai doesnt put one in the car when building them?

4. Can cars go their entire life without a catch can and still be fine?

 

3) In addition to probably other reasons, it increases cost and end-user maintenance. You really expect ME to dump some old oil?



4) Yes, or they wouldn't have designed them without

 

A one year old car does not need a catch can, you'll be fine. Spend that money on a minor service or something.

 

Yes you need them on your turbo car. And you need two separate ones. I have two of those cans. I didn't use much but the can, a reducer and the clamps. I used ~7' of 7/16", 6' of 3/8" and 2' of 1/2" fuel line hose, two 2" pipe electrical conduit clamps for mounting. You also can add a 3/8" hose x 1/4" NPT hose barb too for the drain. And I used 4 1/8" pipe plugs to plug up where the sight hoses are mounted. The hoses turn black after a year and you can't see the level in them. I use a 3/8" hose with a 3/8" bolt and clamp for the drain. It is snaked under the car and you can get to it easily for draining when you change the oil.



The drivers side will fill much faster than the passenger side. The drivers side too is a much gunkier mess, it's a mix ow water and combustion by products. The passenger side is mainly oil and really does not accumulate a whole lot but it's good to keep it out of the turbo and IC.



I mounted mine on the frame rails behind the bumper near the edge of the radiator.

 

I would use them, especially on a turbo car..



Read answers for 3 and 4 above, I don't need to elaborate further.



Also on the GDI Gen coupes and other GDI model cars, a catch can is also more helpful, as there is not benefit of the fuel injectors 'cleaning' the intake path. Since GDI vehicles do not inject fuel on the intake side, the intake side of the motor tends to get gunked up even more.



You can go even cheaper than that on a catch with with a finer filter element by using the air filters for compressors. If you just slightly loosen the filter element on those, it will flow plenty of air but help keep the blowby/oil out of the system and allow it to condense in the can.

 

Yes. Get them.



If you don't, it will put oil through your turbo and into your pipes, eventually leading to your intercooler. It'll clog your intercooler and just make it more difficult to cool air and for air to pass through.



Put it on both side of the engine. It's just better. Keep oil from where it doesn't belong.



My catch can came with clear hoses. I had them on for a few days, then realized the heat was warping them and would probably eventually bust, so I bought fuel line.



A catch can is a catch can, just an empty can that the oil empties into - unless you get one with a filter or multi-levels so it keep the oil separate from the return air.
