Oil metering pump ?
 

Where the OMP mounts to the front cover there is a welled out area to the left of where the pump's arm slides into the gear slot. When I put my OMP on, a liitle of this welled out area is showing. The top of the pump is not square, it runs down from the right bolt hole to the left bolt hoe, and this is why the welled out area is showing.

Is this normal?

Thanks...Scott
