The engine oil is drained and the sump is off. When the sump is cleaned up, I will post a picture of it, as it is quite blingy.
The only thing wrong with the sump was the sump plug, which was a cut down M12x1.5 bolt.
This is going to be replaced by the Fumoto valve in the picture, which is a much neater engineering solution. They're available in the UK from www.quickvalve.co.uk
