Leak

I have a slow leak on the back side of the motor between the firewall right up above the CV joint and the transmission, it looks like engine oil. It's just behind the valve cover. Is there a gasket or oil sending unit anywhere around there? Another thing that might help me is a picture of the schematics of the motor or something relavent to that.

is it on the firewall or on the motor? where exactly? i read above the CV joint and tranny, but there r two cv joints at the tranny... if u'r sayin on the motor at the back of the valve cover, then it's prolly the valve cover gasket leaking. if it's on the firewall, then check for where it's getting sprayed from onto the firewall.
