Oil leak

Hey guys I just bought a 04 ep3, I'm finding out this car has a lot of demons from last owner.
To start out I've replaced the wiring harness under dash not at all a fun job, notice a oil leak at valve cover. The valve cover stud was snapped replace it no big deal. Foulds a 2nd leak right above drain plug on oil pan there is a tie in with hose. It's not turbocharged that would be the only reason there would be a tie on. I've routed it looks like it's going to the vtech solenoid, sorry this is so long my question is why would that be going to the solenoid because looking at a new oil pan does not have that there. Much help would be very appreciative

Update the line from oil pan is going to the oil pressure solenoid if that helps would add pics but don't know how.
