A minor point, the oil should not be pressurized by the time it reaches that
seal.  There is a cavity between the seal & bearing, with a drain hole back
into the sump.  Some folks have theorized that the hole isn't big enough,
and drilled additional holes, but I haven't seen the need myself.

Also note that some of the rubber seal kits on the market have the wrong
instructions as to how small to grind the crank.
