[QUOTE=marinabrian;2676640]Black O rings are original spec, pink O rings have changed colour due to being in contact with a chemical that is red in colour.

Brian - possibly a slight misunderstanding from my shoddy description, but the new O rings on the new pipe in a sealed bag from an MG dealer are a pinky colour and exactly the same colour as the O rings which came off the leaking bits at 5k.

So they hadn't changed colour, just flattened off!
