Hi there
I have no fibre washers on the screws on my A10 and they do not leak. But on my A65 I have to put fibre washers on both the level screw and the drain screw or they will leak maybe they are not seating correctly in the casing, I would fit a fibre washer and see what happens. Have just looked at my parts book for a  1954-57 A7 A10 and they show 2 fibre washers part No. 67-1709 Primary chaincase oil level and drain washer (fibre)
