breather hose
« on: December 21, 2010, 04:33:38 pm »
im looking into doing custom intake and was wondering if i could just put one of those small beather filters on it so that i dont have to connect it to the intake pipe... can i do that? whats the purpose of the beather?

Idea is to use the small filter in this kit thing.. http://www.ecstuning.com/Volkswagen-Golf_IV--2.0/Engine/Intake/ES4681/ i know its not for same motor, just for example

The breather will have air/oil coming out of it rather than going in - a small filter like that combined with an engine with any significant degree of blowby would be an oily sponge in no time.  Ideally you do want to burn the blowby - it's got oil vapour in it so it works perfectly fine as fuel.  VW says it help lubricate the valves and upper cylinder walls.

If you really don't want to put it in to the intake for some reason you can use something like this:

The catch can will collect the oil, which can be drained as needed.  Still though there is absolutely NOTHING wrong with putting it in to the intake - you get to use it as fuel, it avoids having another chore to do (emptying the oil tank) and there are potential advantages in terms of engine longevity.

There is a possibility for runaway if blowby is severe.

If you're going to use a catch can, use one without a breather.  The correct way to do it is have a catch can with and in and out lines.  The oil comes into the can hot, and because the aluminum is cool, the oil cools and drops to the bottom, usually along with a large amount of moisture.  the oil and water stay there, and any vapors that can be burnt go back to the intake side of the turbo with virtually no oil.  I dump mine every couple months, depending on moisture, and there lots of oil and water.

You will find if you use a breather like this, you will be able to smell it and it will leave crud all around the outlet of the breather.  I don't know about you, but I like me engine spotless and no smell of diesel or other vapors. (I've tried the breather, doesn't work!)

its gonna smell if you just use a small filter. the car will always smell like blow by.. a road draft tube would be better than that..

i have basically a road draft breather setup on my car.. equipped with a factory VW oil separator.

I like my engine spotless as well, ok so that idea is  out of the window.. can i possable weld a joint onto the custom intake that fits the hose? prob eh? my car doesnt burn oil to much. i did oil change 3500kms ago and i prob put about 25ml in it to top it off.

should be fine to drill a hole and thread in a hose connection, or weld one on.

whats so custom about this intake? are you trying to 1up the vw air box? its gonna be hard to get much better than a modified stock air box. i wish i had a stock air box to run..

I just have a K&N filter attached to where the stock airbox would be.  Still have the factory intake, just not the airbox.  Works fine...  You can hear a big difference in turbo noise with the cone-style filter instead of the airbox! 

Only reason I didn't stick with the stock box is after loosing the fenderwell snorkel I kept finding my air filter completely SOAKED.  The oil on the K&N keeps water from sticking to it.

heres what i did.. used a stock T3 intake for my VNT, and then extended it with a piece of ricer intake..



works great.. isnt too loud. and it stays half ways clean too.

I have done this also, and it does make a big differnts in sound thats for sure, can really hear the turbo.. i might just do it again and skip the pipe.

^^^ That's exactly what I have... I've been thinking of building a sheetmetal wall that keeps engine bay heat away from the filter - tons of room to get great airflow from beside the radiator.
