It's done now and I am not going there again willingly. I somehow do not think it is that important and the main downside would be a leak at worst and if they persisted with the original tightening sequence for some years then it must not have too much of a downside..

So far so good and no leaks from the sump or the Fuel pressure regulator.. The bottom of the car is DRY, well dry for a Land Rover.
