Just back from some more traveling, yay, I’ll try to post some photos in another post. I put on almost 20 hours this trip, added 1qt of oil before the trip, and another qt before putting on almost 8 hours flying today, some IMC and cold weather today. At the end of flying today, I found some sluggy oil on the top of the cowling. Very sad to see because I just had the crankseal replaced earlier this year. Previously it would only leak on longer flights >3hrs and would lightly spray the windscreen. Would that really fail again, or is this some other issue? Last time though the oil was a light color oil. This spill on the top of the cowling is darker and almost seems soapy or some weird consistency. It did not spray onto the windscreen. The oil is getting dirty, last oil change was roughly 3.5 months ago and <40 hours tach so it is time for another oil change. I sent a text to my mechanic, here we go again.
