This what Barry Halton MkIII DHC had to say:
Dear Chris –
I fitted your modification to the Mark III oil filler cap the other weekend and what a great bit of kit it is. It was very simple to fit and works superbly. I used to get very fed up with the constant leakage of oil over the top of the engine but your o-ring fix has cured it completely. I did about 300 miles over the Silverstone Classic 2012 weekend and there isn’t a new drop to be seen. Now I just need to clean off years of previously acquired mess.......
Best wishes – Barry
