Adding a breather system to an aircooled VW engine

[@VWJawbreaker]

Man that hard line looks good.

Thanks. I think I'm going to redo it. I don't like the bends. Should get the job done tho.

Been catching up with your videos and appreciate the work you do. You gotta inspire a lot of younger wrenches. The engine bay cleaning cracked me up because my bay still ha pasture dirt in it. Great stuff Jason.👍👍👍

[@OldVolksTV]

I appreciate the support!

Nice work. I had the idea of machining out one of the tinware retaining screws on the top of the heads each side of the engine and screwing in a 3/8" or 1/2" barbed fitting. I was going to run some hose up to the bottom of the air cleaners if there's room. If not I will run 180 degree fittings to the tops.

My preference is to not run them to the carbs, but my engine builder said that's the best way. I like a seperate breather box. This made it easy to pull the motor, so I'm sort of OK with it.

Great idea, solution and work!

Looking nice clean all that performance stuff ! Thank you !

[@chadroy16]

should check out some brands of pliers wrenches, you can get soft jaws for them too, for clamping parallel surfaces in place of locking pliers, they dont bite in and damage stuff.

You cracked yourself up flipping us off 😂

[@OldVolksTV]

Hahaha. Never grow up.

Hi, when the elbow is fitted drill a small hole through one flat of the nut and thread and fit a small cotter pin this wil stop nut coming off.

Looks clean , although I'm not about to feed hot crank case gas to my carbs on a vehicle that isnt required to be smogged. Just run a breather box.

[@OldVolksTV]

@@smokepeddler using the slight vacuum from the carbs will help draw out the pressure from the case and prevent leaks.

[@smokepeddler]

@@OldVolksTV valve cover breathers mist and puke oil. As long as you vent your crankcase and valve covers to a breather box you will not have positive pressure that cause leaks. You don't need to pull it with vacuum. The only reason why vent lines are routed back to the intake is for emission reasons. If you want to create negative crank pressure run a pcv valve and purge the gasses through the exhaust to pull instead of vacuum from the intake.

[@Fahrfrumlosin]

Why suck the nasty oil vapor into your intake?

[@OldVolksTV]

That's how the factory set up the breather. The slight vacuum in the filters helps pull the pressure out of the crank case. It's much more efficient than venting to the atmosphere (breather box).
