The internal oilway is drilled in three dimensions, X, Y and Z. 'X' and 'Y' can be cleaned from the outside, however the 'Z' axis that joins them internally is a blind passageway only accessible from a blanked-off drilling hole on the outside of the casting. We had to remove this blanking and the picture shows the entrance after cleaning the oilway and re-tapping. It is now ready to be blanked off again.
