did you get the exact right seal???
if you did it should not leak at all, not if your block`s not warped or cracked.
you know you can allways get the motor seal kit from prohopper wich is great and prevents oil leakin` in the motor...

just check the surface on the block where the seal goes so it`s all clean and straight, thats very important, clean everything up so it sticks real tight against the block, it really should not leak if you do that...

did you change the SHAFT SEAL? if u did...and u still get oil..take it back out and brake clean the shaft seal and the hole it seats into on the block..then apply silicone to the inside of the block where the seal seats and reinstall the pumphead..the silicone will ensure a tight seal..shouldnt let any fluid by

To have the oil leaked into your motor means the following 2 possiblities:

1) Your pump shaft seal is teared around the shaft allowing for the oil to leak or the shaft seal is deforemed and can't seal around the offset of the block properly.

2) Pressure port pin hole leak. I would look at the pressure port where the gear shoots the oil into the block and look at the 90 degree turn. If the machining is not done properly, the possiblity of breaching into the shaft hole wall becomes likely.

Let me know if this helps.
