Default Oil leak

So I have a 1991 xj with the 4.0 and it leaks oil really bad on top of the valve cover and all over the place near the back passenger side. It gets all over the heater hoses and distributor and smokes pretty bad. I have looked at everything and i have no idea where it’s coming from even after cleaning it and running it several times. Any suggestions?

CCV system may need worked on. Any oil in the air filter box? Ever replaced the valve cover gasket?
