Default Oil Leak

Is there anything directly below the #6 valve cover on the back of the motor that can leak oil? I've got oil spraying onto the firewall from right there. I thought it was the valve cover but I swear I've screwed with it 3 or 4 times and its still leaking. Just wanna make sure there's nothing else back there before I pull it off and clean it again.

unused diesel fuel from the injectors joins a "T" then returns to the tank back there

Yeah I saw that but this is definitely 100% oil. Guess I'll screw with the cover some more. I'm wondering if its bent or something.

All gaskets were new, but I think I figured it out. That eyelet that bolts up right next to it is bent and was pushing it off possibly just enough to make it not seat up all the way around. We'll see tomorrow.
