According to reports on Motoring File and discussion on White Roof Radio there is a rash of Oil Pan Gasket failures as of late. Being mine replaced at 30k or so miles since the pan was pulled to add caged oil pickup I've not seen this issue. The issue causes a slow oil leak and has been possibly attributed a few blown engines. Replacing the gasket is not an inexpensive fix. The part is inexpensive in the MINI realm at around 60 bucks but the labor is about 5-6 hours making this a 600-800 dollar fix. Most of these cars are now out of warranty and lets face it, MINI has no real incentive to re-engineer the gasket so this is a big hit to wallet. Have you had to have oil pan gasket replaced?
