Andrew,
This hole is part of the cross drilling linking the outlet at the bottom of the main filter chamber to the internal front to rear drilling which feeds oil to the engine. There was no need to blank this end of the drilling off as when fitted it is against the side of the block. I hope I have made myself clear.
Peter.

Peter,
Yes, I do now, thanks. I've had another look at it and I can see why it's there and why there was no need for MG's to blank it off as you effectively do that when it is bolted to the block.

Andrew,
On our P type I found that because the face of the filter was not exactly flat to the block that oil was leaking out of this hole past the gasket, in spite of carefully fitting what I thought was a well made gasket using Wellseal. Lapping the filter face made no improvement, so I guess there are small irregularities on our block face. The telltale oil marks on the gasket confirmed this.
Having studied the design and realising that the hole in the filter housing was purely a machining hole, I made a very slightly tapered plug to fit the hole. The housing hole was tapered accordingly. Plug tapped in, lapped flush with the housing face - belt and braces I know, but no further leakage.
