fixing leaking rear main seal

my engine is brand new.the main seal leaks because i failed to use enough sealer on it and it sat in the car waiting for all of the stuff i needed actually wanted not needed in everyones eyes.... anyway i think it stuck and moved on fireup.it leaves a little puddle when shut off and they will never let you race it at sonoma or sac leaking plus i dont want to be the dumbass that made everyone wait for cleanup .no one likes that guy
