Crankcase Breather Help

[magoconnor]

Hello. 

So I bought this motoforce crankcase breather, but I'm not sure exactly how to install it. 
I know it should be switch out with the oil dip stick, But the thing that bothers me, is these things usally comes with a hose to guide the oil away (this did not come with that)

Anybody knows this product ?

Ok, but won't the oil just spray out everywhere ?

I do not see how that device will do much of anything about crankcase breather pressure relief. If indeed it relieves the huff'n'puff as the piston reciprocates, the volume(49.6, 63, etc cc's or ml), has to go somewhere. The actual pressure on the downstroke should be closely balanced by the 'vacuum' on the upstroke, for very little 'pumping loss'. The web site exaggerates the effect on performance. It is only when you add the turbo, and start to blast some fuel:air mix past the rings(more than normal blowby) that you NEED to let the crankcase breathe to much degree. Other than that, a vent to atmosphere, using a looong large tube or a 'catch can' for some volume so you don't get a lot of huffing and puffing in and out, would handle any crankcase breathing needs if the engine is in good shape ring-wise.

The thing I don't get about this thing is the back screw.
Has anyone tried this thing?
