oil leak front passenger side 2000 zx3

I have an oil leak on the passenger side of my 2000 zx3. I am not very familar with all the parts, i'm not much of an auto guy but i am trying to see what the issue is. What i can tell is that the leak only occurs upon starts, I can drive for an hour and park and return to the car hours later with no leaks, just starting I assume when the system becomes pressurized. That area is about 6" from the the inside of the passenger front wheel. It appears to just squirt out almost like 3-4 holes at once not just one stream, could be from a box looking part but i 'm not sure because i just began trying to examine the source. I was just curious if anyone might have any ideas what is leaking and maybe what am i in for as far as repairs. I do have a buddy that is a auto mechanic that could help if its an do at home type job. thanks.
