I've bought 1 for each side , shape is like a tick or Nike swoosh. They are R&G. I read on another forum a guys fitted one can't remember what side and he's now got a very slight oil leak. I can wait till its first service and get the garage to fit them but I'd feel a bit silly if it was unnecessary. So question is , should I be worried about any fluids from either side leaking out or just go ahead and fit them ? I fitted a set to my 20th anniversary blade with no issues. Thanks in advance.
