Can someone tell me how to remove the oil filler assembly from the block on a Peugeot 306 XLD? Reason: The oil vapour hose is split. The lower hose end is fixed with what looks like a Jubilee clip but without the screw. Its a use once fixing. I cant get to the clip so I will have to remove the part the clip and hose are attached to which is the oil filler assembly. There appears to be a connection from the base of the oil filler assembly into the engine block. Can someone tell me how to remove the oil filler assembly from the block? I'm not referring to oil filter but the oil filler assembly. Many thanks
