I searched and i found too many informations leaving me unable to decide what should i do.

I have a stock EK4, i'll be putting a CAI on there and at the same time i'd like to do something about venting my crank case. Later on the b16 will be boosted. I want to do the catch can myself, but i'm not sure if i should tap the valve cover on the stock venting point?
Do i need to tap it on a different location as well as the stock one?
Should i just have a valve at the bottom of the can to empty it? Or should it be routed somewhere to empty it self?
I'm thinking of making a similar setup to this only without the top fillter and put in some kind of mash to help the oil condense.


I need something that would work now and when the engine is boosted. I would consider moving the vacum line from the IM to the intake side of the turbo when i'm boosted.

I would say go with the Endyn kit. It comes with everything you need, just empty it every oil change.

Why does it have a filter? it kinda defeats the perpous of having vacum hooked to it.

How about the other questions about where to hook it up that will be good for NA an boost?

 

Many people have used this on boosted cars and N/A. The reason for the filter is just like you have on you drawing is to let clean air out hints: BREATHER KIT!!!

 

go with the endyne its about one of the best kits out there

 

You don't need to have the unit hooked up to vacuum, but you can take the filter off and run a hose back your intake before the turbo if you feel a need to run the car with savaging. This system just vents to atmosphere. You may need to run a closed loop system if you live somewhere with strict emissions regulations.

 

Thanks for the input so far guys, but i'm acctually looking to make something on my own. I'm a student and i'm not paying money in the USA+shipping+costums to Europe on something simple as a catch can.

I think that there should be a clear answer to weather venting to atmosphere or hooking up a vacum line is better? This is what i'd like to know. Is either setup prefered for NA or boost?

The picture i posted is hooked up to vacum, as far as i understand it, the filter is there just to prevent the steel wool getting into the engine. So the other Endyne kit has two lines from the valve cover or one from the block and one from the valve cover, basicly just catching the pushed out oil?

 

This will work, but the internal design should be changed to match the drawing you origionally posted. http://www.geocities.com/eurot...42831

 

This is exactly how i'd like to make mine, only i'll make a wall in the can to make sure the oil that gets in goes all the way down so it gets filtered instead of just taking the short way towards the vacum line.

Only thing is, what when i get boost? Just change the vacum line and place it in front of the turbo?

How can i tell if my setup is working good? Clean IM? If placed infront of turbo, will the vacum be too strong and pull out more oil than i'd want it to?

 

That is correct, once the car is boosted simply move the vacume line in front of the turbocharger (So it will be between the filter and the turbo). If you want to see if the system is working then simply disconnect it. If your engine is in really good shape you might not notice any differance at all. The only real issue is that you have to find out what the part number is for the barbed plugs that go on the back of the block.

So you say that i should tap the bolck? I thought of pluging it into the existing valve cover hole, where the stock system was.

Also is there a need to drill two tap points infront of the valve cover. This seemed popular with turbo guys.

 

It needs a filter to allow the gases to exit the catch can. This is illegal for imissions, because it is emptied out instead of being routed back into the intake manifold.

If you don't have a filter on it or a way for the gases to excape you might as well not put one on.

I'm not sure i get you. I decided to go with a can hooked up to vacum, not an open setup.

 

Look at the pic of the enyen kit above, it has a line in, a line out, and the filter on top to release the gasses.

 

If the engine is a B series there are two plugs you can remove from the back of the block, if you do that there will be no need to tap anything. If the car is a K or D series you will have to tap some holes to do it properly. I have seen people do it off the valve cover, but personally I would rather have it running off the back of the block away from the heat of the exhaust manifold. You can run a T and just attach it to the back of the valve cover aswell if you want.

 

Yes i have a B series and on your advice i'll tap the block. It was just that i wasn't sure if it's better to make two holes in the valve cover. I found the part numbers for the fittings while searching the forum, now i'll have to do it again. Those two plugs that i'll remove they will be hooked up to the catch can and bringing the oil vapours in, right? So i'll have a third line from the can for the vacum and some kind of valve at te bottom to let the oil out.

 

Yes, sir.

 

DO THIS!!

I have this setup and the endyn setup on my boosted B18C

 

Thanks P1 !
But now i'm having trouble finding that post with a picture of the two plugs for the back of the block and their part numbers. Well i'll dig out the numbers some how.
One last thing, how will this influence the enviormental impact of my car. The way i see it it should be the same as it is now. But i want to know what others think or even know.

mike1114, is that really necesary to have two catch cans? You have them both vented to atmosphere?

 

On a turbocharged car yes two catch cans is necessary.

It is not necessary on NA setups.

 

As long as you run a closed loop system with catch can run to a vacume line for scavaging its likley better for the enviroment because you will burn less oil. Personally I don't feel that two catch cans are required for cars that are running boost. But it won't hurt.
