I have been told the 20B motors suffer a bit with breathing? I am in the process of sorting out a new breather system and interested to see what others have done? Options such as venting to atmosphere or running back to the sump or elsewhere? What seems to work best?

Thank you

Never had any issues with min just being vented...

 

Vented to air is that? With a filter? No spray around the engine bay? Was thinking of breather to turbo compressor inlet to draw fumes away. But don't want to do that if much oil will pass through.

 

If you plumb it back to your turbo inlet, make sure you put in a PCV valve.
If you are just venting it and not going with an oil catch can setup. enlarge the tube/hole that your drawing off to reduce the airs velocity so not so much oil gets carried with it.

 

Thanks for the advice. Maybe I will try venting to air first and run it under the car to minimise fumes in the car.
I have put a 5/8" stub on the oil filler neck right near the base and sticking vertically. The bore is about 1/2".

Cheers
