I was looking the engine over this morning and found a build-up of belt dust on the port camshaft timing belt sprocket. The engine has around 60 hrs on it. I know there has to be a certain amount of wear-in on components such as this but was just wondering if anyone else has noticed this on their motor. I would be interested to hear others opinion on the seriousness of this or if it's something to ignore. One thing, it being new and squeaky clean, makes things like this noticeable.
