Oh dear, I've bought the car of my dreams and now I ind an oil leak:frown. I haven't looked too in depth, that's tomorrows job:thumbsup. I think from reading the forum that the sump seal may have started to let by. Has anyone changed one in a 2000 E38 (4.4l)? I just want to know how difficult it is? My main worry is jacking the car up and climbing under it; it's a heavy lump after-all. Advice would be appreciated.:confused :confused :confused :confused
