With a pick or flat head screwdriver, carefully pry up on the edge of the seal where it meets the engine case. You may need to use a small flathead screwdriver in order to clear away enough material so you can see the edge of the seal and\\or get your screwdriver underneath it. Using a Phillips-head screwdriver, gently pry up on the seal around its perimeter while keeping an eye on the orientation of the screws that hold it in place. Once they have been removed, pull the seal free from the engine case.
