Valve Cover Cracked, Oil Leak...

I think the valve cover itself is cracked. I got it used when i was doing the romeo headswap. There was a scrach on it but didnt think it was cracked. Now when i drive it, it seems like oil seeps from the cracked area. The mechanic checked under the car and the heads and he said its not the head gasket and most likely the valve cover.

Where can i find a passenger side valve cover with the oil filler? If anyone has one they want to get rid off please let me know.

Thank You
