Leak?

[southernAL]

Anyone experience there valve cover leaking? Tractor is ck2510 with little over 200 hours. Not sure if it's the valve cover or something else, but it's definitely oily residue mixed with dirt and dust.

You definitely have a leak somewhere. I would buy some engine cleaner and hose it down to get a clean start and watch for where it is coming from. It does look pretty wet around the valve cover. They just tighten down snug, not too tight or they will warp.
