Oil Leak - Help!
I have a 2006 Ultra Classic that I recently did a TMAN 95 build on. I have developed an oil leak. The oil shows up on the 4th and 5th fins below the head gasket on the front cylinder. I went through the oil cooler lines and even reinstalled the oil cooler housing using gasket sealer on each side of the gasket...my thought was that oil was blowing up from the oil cooler somehow. I then let it run until everything got real hot and I looked all around and couldn't see any obvious leaks (checked around the push rods tubes, etc.). After it cooled down, I washed it with lots of simple green and rinsed everything real good. Then it sat for a few days. When I went to look at it again, the oil was on the front fins again and it had dripped towards the left side of the cylinder and then dripped down onto a bolt on the frame. Some other things to note: it had plenty of oil pressure when running and it runs great (no smoke out of the exhaust or anything, plenty of compression, etc.); when it was cooling down I heard a gurgle type noise in the front cylinder (sounded like oil working it's way back down); I have a doherty powerpacc and I had it running with the just the powervents and there was some white smoke coming out of each powervent (not a whole lot but I was able to see it). Tonight I pulled the rocker cover, then the rocker box and examined and I could see nothing wrong. My understanding is that once oil is up top, it simply drains towards the exhaust valve and then flows back to the bottom end. Is there anyway oil could end up on the cylinder fins other than through a blown head gasket? I'm just not sure where to go from here and will take any input this forum is willing to provide. When I ride, the wind blows the oil from the front cylinder to the back of the horn where it accumulates and then blows all over the derby cover all the way back to the front of the rear saddlebag.

Found It
Well, I finally found the leak. The oil drain channel in the front of the cylinder had two leaks in it (around the 4th and 5th fins below the head gasket). I would have never thought that oil could leak through the clyinder wall, but it happened. Once I had the cylinder off, I plugged one end of the oil channel with my finger and blew compressed air (using a rubber nozzel on the end) in the other end and I could immediately see spurts of oil and air blowing out of two small holes in the cylinder. Unbelievable. I asked the dealer and he said he sees a "pourous cylinder" about once every 5 years. TMAN has a take off cylinder that he is going to bore out for me and then I'll be back in business. I feel so relieved because I have been chasing this leak for a long time now. If I take a picutre I will post it.
