have been chasing an oil leak from the cam end bolt area which seems to be a common fault with the 500/550. I had replaced the sealing washers but still leaked so checked out the l shaped bracket that hods the end cap on. This proved to be bent and misshapen so replaced it with a spare i had. not now leaking but for good measure i am doing a modification which Trigger uses to make sure it stays oil tight. Have been out a couple of times when it has been a bit milder and running well, handles great and sounds great.
