Arwen,
No sign of a 2mm diam breather hole in the right axel tube. Maybe that’s why there is a flexible tube mounted on the top casing of mine. But why no standard hole in the axel tube?...... mystery. But then again no more so than with a lot of other Morgan “mysteries†haha.
Cheers, Neil
Took me a lot of digging around to find mine - it was well plugged up and used a drill bit (by hand) to clean it out.
Your flexi-tube may well have been a modifcation - I know on my Land Rover, the Salisbury had brass vents, and they were often replaced with hoses for wading.
