Here's one you might be interested in, my sons RR5 started having a very strong odour of petrol from and after a couple of days you could see staining on the sprocket cover a few more days and petrol on the garage floor. Time to investigate, pulled the tank off took it into work, under macro could see one of the spot welds on the bottom of the tank cracked and leaking fuel. Drained tank and repaired as photo.
