I cannot say that I know of any good diesel mechanics. JCBritish is where I have gone for my petrol Disco. I did not know about RoadsideWerx so thanks for the tip – he is close to home. I also try to do as much of my own work with manuals, forums and YouTube tutorials. The “Land Rover Toolbox Videos” are pretty great.
We are just across Hosier Pass from you, near FairPlay. Have to get together some time.
