Had some spare time so I thought I would check the engine out closely. I can see the breather gasket is leaking but I could not trace anything that would cause the moisture you see on the top of these two cylinders where they meet the crankcase. No appearance of oil making it through to the bottom of the engine either. 75000miles. HMMM ...is it coming from the nut above. The film looks lighter but it does show a flow line. Can I tighten that up a bit? Any other thoughts? thanks Doug

Doug,

It looks like the case through-bolt O-rings are slightly seeping and that's not uncommon at all.

One must remove the cylinders to replace these so I'd not be concerned about this until the top end needs to come apart for a valve job.

Thanks for the input Steve. That makes sence and I guess the air from the fan stirs up any leaks over time.
