Well, you could if you are willing to pull off the crank damper first.If it's just the crank seal pop out the old one and insert a new one.You'll need a piece of pipe or a socket that will fit over the crank end to drive the new seal on squarely but without striking it too hard. If it leaks thru the cover to block gasket you'll have to also pull the crankcase pan because of two inside mounting bolts.Replace the crank key also when reinstalling the damper.
