The gasket behind the breather on the front of the engine block, behind the headers that has the pcv hose going from it to the actual pcv valve.
Round, 3 uneven holes, graphite gasket thats leaking oil on my headers and i cant find anything about it on any Ford dealer web site!!! WTF!
Its an engine block oil breather? When i took it off, there was at least a 2" hole, right into the inside of the block; i touched the crankshaft..
