ill second the snout just comes off, no need to remove the blower. taking the snout off limits what else could break on you. like injector o rings and vac lines and such.
open the drain fill cap, suck the old stinking fluid out. lay some rags down a top the water pump and in front of the snout, cause more oil will come out when the snout its opened up. leave the rags and spray down the inside of the snout with brake cleaner and mop up the mess on the engine.
