Hey Brian, when you say "cam cover", do you mean the valve cover or the upper front cover? When I got a new valve cover gasket it came with a funny little square horseshoe shaped gasket, 6 months later I figured out (with some help here) how to and where it went, leak is now gone (from that part of the engine)
