I have a very slow oil leak, and I think I've traced it to originating at the joint between the rear rotor housing and
rear side plate.  I'd rather not open the engine up to apply sealant, but it is half a day's work to disassemble
everything down to the point I can get a torque wrench on the case bolts.  I'm conflicted on if I should go ahead and
break the case open if I'm down that far already.

How likely is that the seeping oil can be solved by re-torquing the case bolts?  If the torque is correct, is it likely
that the end plate is warped?

Would a good plan be to check the torque, and only continue disassembly if there is no movement?  That is assume that if
it is torque properly it must be a warped plate or missing sealant, but if the torque is low bringing it up to spec will
solve the leak.
