oil catch can install
 

What is the best way to install one on a evo.

Is it not the same as DSM's?

Re: oil catch can install
 

I have never installed one so I don't know.

Re: oil catch can install
 

The way I did mine deletes the pcv valve. Just screw a nipple into it's place, run a hose from that and the other valve cover breather port to the catch can. Then have a seperate hose come in through the top of your can and go to your intake pipe.


I'm on a blow-through setup though, so I don't know how this would apply to you.

so like this

Interesting. On the X the stock line runs from the valve cover to the intake. When I install my AMS intake (which doesn't come with the inlet) I was just going to run the line to the catch can. I didn't think there was a need for an outlet on the catch can. Need to research that.

Re: oil catch can install
 

Ideally you're going to want 2 catch-cans for a proper install and to maintain vacuum inside your crankcase.

VC breather ---> MAP crankcase vent (optional but recomended) ---> catch can ---> intake pipe

AND

stock PCV ---> catch can ---> MAP crankcase vent ---> intake manifold

Re: oil catch can install
 

You really need two of them.

Re: oil catch can install
 

If you want to route both the breather and PCV to a can then yes, you need 2. If you do just one can though then pick which of the above two is more important to you and go that route. I personally have 1 can setup between the VC breather and intake pipe.

Re: oil catch can install
 

Yes except you have the line going to the intake manifold, not where the pcv valve use to screw into the vc.

Re: oil catch can install
 

Doing that, without any check-valves, is a terrible idea since you'll be pressurizing the catch-can AND crankcase during on-boost conditions!

Re: oil catch can install
 

There's no pressure in there, only vaccum. I have the 3rd tube going to the intake pipe, before the turbo with an inline filter.

Re: oil catch can install
 

How is there no pressure when you have a line run directly from the intake manifold?

Re: oil catch can install
 

I meant to say he did it wrong, that line gets ran to the VC. I keep thinking DSM's where the pcv valve goes to the vc. Obviously that won't work hooked up to the intake manifold.

Re: oil catch can install
 

Evos and DSMs have their VC breathers and PCV valves setup in the same way, just in different locations.

Re: oil catch can install
 

Do you have a pic of it under your hood?

Re: oil catch can install
 

Why not have both the VC outlets go into the intake pipe? The PCV going into the intake mani is pressurized under boost so it does nothing. If they both go into the intake pipe the turbo will be sucking air out from both VC locations at all times. Granted this will probably look messier, but oh well.

Re: oil catch can install
 

And all that blow by going into the turbo? no thanks.

The 2 red hoses go to my catch can. Then the green hose goes to my intake tube. No pressure, only vacuum.


Thats the point of a catch can dude, to catch the shit and suck out vapors. It's a better way of doing the same thing the factory did in my opinion.

Re: oil catch can install
 

This. Just run both VC vents into a single catch can and then to the intake pipe.

Re: oil catch can install
 

There is more vacuum from the intake manifold during idle/cruise than the intake pipe ever sees so its beneficial during off-boost conditions. The intake pipe is only under vacuum if the filter is unable to flow as much air as the turbo is trying to draw in which won't happen while idling or cruising.

Re: oil catch can install
 

Oh man, I just thought of a crazy setup that lets it go to wherever has the most vacuum, either intake pipe or manifold. It's complicated, maybe I'll draw it in MS Paint tonight. Also probably not worth all the hose it would take.

Re: oil catch can install
 

You should see what we designed for Scheides car :)

Re: oil catch can install
 

I think there was a misunderstanding there. Asshanson, I thought you were saying to put both the breather and the PCV to the intake pipe with no catch can in between. lol
