I want to replace the seals on my OPRV (late type). The external one is a no brainer, but how do I take the valve apart to replace the inner seal???

Don't think you can

I separated the parts with a vice and a bit of force - being careful not to mark the shiny parts! I then replaced the inner seal (available from Porsche), lubricated and applied more force to get it back together.
