Oil leaks own. I've gone through around 30 litres of oil in the last 1000 miles. Mostly through quick-succession changes for the good of the engine, but some through leaks. I've had to remove and rebold the sump (RTV rules!) and replace some washers/seals to get things oil "tight" but I think I'm nearly there. At least, I'm touching wood as I write this (literally).
Pop over to Baz's photo site (cheers!) here to see my car from the Hook meet (ClubCalibra) yesterday - see, she's on the road baby! :D
