Never seen or heard of a hole, that relieves pressure off the seal.
Ramm, just try the sealing ends 90* apart can't hurt. And like I said, I never glue the seal in the block or retainer. Just place it in there. Place lower half of seal, put crank in, then take upper half of seal and work it around crank until you parting lines at 90*. Then put the retainer in
