How are you going to know you have the right amount of oil in there? That hose is usually a vent to equalize pressure.

I have to put a new seal on it and I just want to get some oil in it because I need it to goto work ,then I will fix it when I get payed,just wondering if oil would go into the rear end cavity through that hole

probably not. air would have to be coming out of the tube at the same time you are trying to put oil in.
