Help Finding A One Way Valve

[magoconnor]

Hello. 
I'm having a little trouple finding a valve like this one : www.google.com/search?client=avast&biw=1920&bih=938&tbm=isch&sa=1&ei=5hI5XIfiIYqgjga2hYTwBQ&q=naraku+crankcase+breather&oq=naraku+crankcase+breather&gs_l=img.3...7921.10273..10607...0.0..0.178.761.9j1......0....1..gws-wiz-img.58tuor8EPpU#imgrc=VGzrDLSY7MbmPM:

The naraku kit is way too expensive  so I'm gonna put it together myself. 
I already have the piece, that replaces the dipstick + tubing. 

I just need that valve or something that works like it. 

Cheers Mag.

Is it just a PCV valve like on a car?

Just drill out the vent on the valve cover if you need more vent capacity.

US Plastics has many check valves available.

Pull that 90 degree fitting out of your valve cover drill and tap for a bigger one that screws in then put hose on it and a PCV valve at the end of it . Route the hose on the frame higher than the valve cover for drain back ... It works awesome I have a Buddy 150 set up for endurance racing and i used the same set up . The Buddy is set up to run wide open all the time Genuine sponsored the build for me about 4 years ago . The motor does not leak a drop even spinning it wide open for 8 or 10 mile stretches . The PCV valves work so well because they do not back draft air thus make a seriously strong pull/ Vacuum . I used this one

[magoconnor]

Cool thanks for the help

I haven't had my hands on the one naraku makes, so I'm not sure if it's a valve or just a straight hole out in to the open air.

Have anyone of you guys, tried the naraku one?

Whats the purpose of one way valve?

Can you give a picture of what the cooling system looks like with connectors etc i might need that in future.

Would this work? www.aliexpress.com/item/07C133529A-3-Way-Air-Pump-PCV-Check-Valve-For-Audi-A4-A6-Quattro-1-8T-3/32899284500.html?spm=a2g0s.13010208.99999999.273.b1683c00Zc1o96

If I block off one of openings.

Cheers Mag.

Do you have a link?

That plastic one will work just plug that port on the side ...

Most cars that have powered brakes(vacuum assist via the brake booster) uses a check valve.

[lilpinny]

At the auto parts store. A check valve.

[magoconnor]

Could a check valve also be used in the fuel line?
I'm running with the gas tank in the floor, so the fuel is delivered by a vaccum pump.
Maybe this will make it easier to prime the fuel line, and keep the fuel from running back down the line.

[FrankenMech]

If you are running hard get rid of that vacuum fuel pump and replace it with a low pressure electric pump made for motorcycles.

The spring in most check valves requires pressure to overcome it. Some check valves use a weighted ball or flap and gravity due to position to operate. The check valves without a spring need to be oriented properly to work.
