Carrying out my annual service/inspection & noted that the sump pan was seriously corroded, this on a L/R 110 with 55000 miles & 8 years old. I scarfed the corroded areas, tapped the sump with a suitable device & it sounded fairly solid, I then painted the sump with suitable protective paint. I will monitor the condition as the season proceeds, I would recommend other owners make regular checks of their own vehicles, I noted an article in this months Land Rover World reflecting another owner's experience with the same problem & the price of a genuine part sump is quite alarming!
