Engine 302 oil leak when running

I pulled the valve cover and took the radiator cap off to compare the fluids and they are both green, but visibly different shades of green. The fluid under the valve cover still feels and smells like oil and the fluid in the radiator still feels and smells like coolant which is weird but I guess this just means it didnt have enough time to completely mix during the couple minutes it was running today. On the bright side, I figured out part of the problem: the previous owner had put the wrong dipstick in it and that was why the oil level was reading wrong. I got the correct one and it now shows full with 5 quarts as it should so at least that part is solved. No idea why or how coolant is mixing with oil all of a sudden though.
