Hi Everyone,
In true Morgan fashion, mine is different again.
I have the cap as pictured but the aluminium tube passes right through it, and is connected to a 10mm od plastic pipe which vents out into the rear compartment.
I have just fitted a small 'catch' bottle on the end of this hose - just to collect the small amount of oil that is pushed out.
Mine is a very early car - no. 004 - which might explain the development.
Regards
Andrew
