I knocked gently on the front of it with a hammer and piece of wood. It came loose. Did remove the fuel union at the pressure regulator, very little fuel came out, maybe a tablespoon. Best to lift up, as there is a steel vaccum line that extends from underside of the cover into the cylinder head, wouldn't want to bend that one.
Is there a way to inspect for the cam oilers that are broken? The metal ones in this engine 'look' fine, but I heard ticking so was looking for offending oilers.
