I bought this LR in 06 and had about 45K miles on it. It was leaking as all Rovers do. I used Auto-rx with the seal leak instructions at that time and it cleared up the leaks about 90%. The front water pump/timing cover gasket is paper and didn't do much for it though as it may have had a tear.
Jump forward 4 years and 40K miles. My head gaskets finally gave up the ghost at about 83K miles as most of these engines do. I had the engine pulled and completely re-sealed as it was just a few hundred more. I have been using the maint. dose of Auto-rx about every other oil change. Sorry I'm forgetful............ When my mechanic tore apart the engine he couldn't believe how clean it was inside. I saw it disassembled on the garage floor and except for a little discoloration on the heads it looked brand new. The inside of the oil pan was sludge free. He said he usually has to take a scraper and really dig to get it out. The bearing caps were spot free as was the crank shaft. The oil pick up screen was clean as a whistle and the pick up tube looked brand new.
I picked it up today and will be putting in my maint dose whan I get home. I can't say enough great about this product.
