I just finished assembling the top end on my '46 EL. I took it apart to fix an oil leak from the front cylinder intake spring cover. I used James gaskits and installed two under the intake and one under the exhaust cover. I'm still leaking oil from the front intake cover! I examined the cover for any cracks and could not find any. I know the cover is secure to the head as I used oversized guides. Any help would be greatly appreciated.
