Just got it firing!
I'm the happy owner of a new 2013 orange Stelvio NTX. However, since the first couple hundred miles I've had a small but persnickety oil leak that I've traced to the drain hole for the spark plug well in the RH side. It's just a few drops each time that blows from the drain hole and cooling fin onto my leg and the transmission housing. Probably a thimbleful every 500 miles.
Photo of leak:
I had assumed it was an issue with the rubber gasket at the top of the spark plug well, the one in the center of the valve cover. But when I did my first service (900 miles) and had the valve cover off to do the valve check/adjustment the gasket looked fine. Even so I applied a thin coat of silicone RTV gasket maker to it, but the leak continued.
Then last night as I was looking at a parts fiche exploded illustration, I noticed that there are two other seals (the o-rings shown as "9" in the screen grab below) that could be the culprit.
However, I'm reluctant to start digging deeper into the engine for fear of warranty issues and it appears that at the least the rocker arm assembly would need to be removed to access these o-rings.
The closest dealer is over 200 miles away and based on what I hear about their service turn-around times I'm thinking I'd have to leave the bike if they do it, meaning two trips there and back.
Anyone had experience with these o-rings leaking and/or the procedure required to access them???
Thanks!
