Look, I am not saying that I need one of these nor that I really believe the the OEM breathers aren't good enough, but when you couple being bored and having a man cave - you get this sort of thing:

Obviously it's billet, high grade aircraft aluminium - whatever that is
Done on the lathe and miller of course from a chunk in my scrap bin. Why 4 holes? Because that's how long it was.
I have ordered some push fit 1/4 bsp fitting for it as these are actually NPT and I don't like them much But you get the idea. The end one is 10mm to go up the snork probably. If I ever bother to fit it.

I'm getting better at this stuff. Ther'e more measuring now and less tongue in the corner of the mouth with one eye closed ....
