Oil leak from top of engine

[MrM]

When checking the dipstick today, noticed small deposit of oil around one of the bolts that holds the red engine cover in place. Also a general misting of oil around the immediate surrounding area. Any ideas?
Cheers

Clean it and then watch it, I would be surprised if it was a leak

Had the same trouble, seems like when you top up the oil a small amount is left in the filler hole and does not enter the engine, my solution is when I top off the oil just use a cloth and clean the shoulder under the cap, seemed to clear the problem.
