on the tail end of an engine swap on 98 hawk that I'm dropping a 99 motor into, I have a tube that I'm not sure where it goes, I think it doesn't connect to anything like a breather or valve relief but any insight would be appreciated...obviously right crankcase. #14 is the mystery tube

 

Just looked at mine. The hose goes over the starter and then bundles with the other vent/drain hoses.
Its connected to nothing on the other end.

 

I first thought it may be a tube from the weep hole on the water pump but not so. Its listed as a Bulk Hose / Vacuum.

 

thanks for the responses
