Is it possible for the bottom engine case to be warped where the sump cover mounts? I layed a straight edge along the back sealing surface of the sump opening and it appears to be perfectly flat. I then layed a straight edge along the opening of the front sump sealing surface and the straight edge dosen't lay flat. The surface itself is clean as can be. I was suspecting the sump cover but now I wonder if the lower engine case sump sealing surface itself could be warped. I have been having trouble getting a good seal along this front sealing surface. It has leaked at the right front corner. I also notice that the fin at the right corner where the leak occurs has obviously took an impact at some time.
