Right so I used these little wood things from my gfs crafting bucket of blocks and wood strips and stuff. They worked brilliantly, I worked back and forth across the front of the motor lifting ever so gingerly with a hand held angled pry bar and rag, and adding one little strip to each side until the cases were split. The seal over there on the left was causing the problem. The one behind the alt rotor. I think..... Thanks for the idea Dave. +10.
Also bomb I agree, those are needed so bad for this issue.
