Well it was actually the second run. The first engine run happened yesterday for my plane. The first was short maybe 3 min, CHT only 160 or so. Climbed out and inspected everything and there were no leaks.
I went off to fly my first flight profile with my Flight Adviser and when I returned I did another engine run and this one was maybe 5 min max CHT 270. (Engine was totally cool before this second run)
What I found on post run inspection is a tiny bit of oil on top of the nut on two different cylinder #2 and #3. Both are the lower left nuts (the large one). The oil appears to becoming up through the threads, oil on top of the nut but not the sides. I have not yet done another run. When I cleaned off the oil no more appears to seep out.
Anyone out there seen this and have any ideas? I am grounded, which is a disappointment, I was really excited to do the first flight today weather permitting, but now I want to run this leak down.
Cheers
Mike
