like a top that now has 3000 plus hours on it and it doesn't appear to burn a drop of oil. However, I have noticed a drip or two from the front seal again. You what they say, the British don't make computers because they can't figured out how to make them leak oil. I've never had an engine failure that I could trace to a lubrication issue in the last 40 years so I'll stick to my 100 hour schedule.
