help finding where check valve leads to

[LVDjetskis]

hey guys, I am having a pretty bad oil leak right now and I found a check valve that had one end missing to it. I have attached the parts catalog for my 2000 gtx and the valve is number 18. I have been looking, but can not find where the other side of this valve goes to.

Yes that is a vent for the oil tank.
