vacuum check valve orientation

[TheJ]

I have an 89 Shadow 2.5l T1 and I took this check valve going to the BOV completely off for some strange reason while I was looking for a coolant leak. Which way do I orient this?



Thanks for looking.

Anybody? I think I'll put the pointy end to manifold vacuum and see how it works.

based on the below link if you can blow toward the bov it should not flow

So in other words put it so the BOV can get vacuum but not pressure? Thanks for the info.

OK cool, that's what I was thinking but I wasn't really sure. Thanks again.
