I have sent back my custom Tech Welding filler tube for the addition of a nipple for the rabbit heat exchanger and am awaiting its return. I would like to say Tech Welding is GREAT to work with and the quality is outstanding.
I have found the exact source of my oil leak.
BIG thanks to Helicopter Ed (Ed Alderfer) for giving me the idea for diagnostics.
My Soob EJ-22 was leaking oil but since it was a light spray that would not leak while on the ground I was having a tough time tracking it down.
Ed suggested I use attached paper towels to find the leak and that is what I did. Using duct tape ( AN rated duct tape of course ;) ) and shop towel style paper towels I made little 'gyro maxi pads' that I secured around the suspect places on the front of my engine. This allowed me to find the leak and make sure that one leak did not soil the towel adjacent to it.
I flew the pattern and when I got back removed the 'pads and sure enough I found the exact spot of the leak: The pressure connection horn on the oil pump ( thanks to the air soob group for IDing the part ). I am now researching the fix.
I have now started flying the pattern without my co-pilot 'old salt' that I have been using to simulate the weight of a passenger.
The difference in flight model is significant.
It climbs out like MAD. It has 1100 foot per min climb rate with my airspeed anywhere between 55-80 mph. (5000 rpm)
After leaving ground effect there is little adjustment needed for lack of a passenger.
I also get WAY more glide time on engine-idle approach on final.
I have been trying some higher speeds and she seems happy at 80mph but the darn windshield bends down at me.
After the oil leak is fixed and I am willing to leave the pattern with her I will get you guys some specific data on temp, conditions, RPM and all the performance stuff.
I am also hoping for a zero wind day so I can calibrate my Airspeed indicator against my GPS.
