Sometimes the tappet covers warp on CX´s...The little round gasket (around the spark plug hole) could be leaking. It´ll drain out through the little water drain holes that run to the outside of the heads. It can look like its drooling from the head, but its just a little drool from the tappet covers.I´d wash the engine down with soapy water while its cold, try some gasket glue on the tappet gaskets, then fire it up until its warm. You´ll get a clear picture of whats leaking in/on your engine. I hope that helps ya out, and good luck! :D
