sounds to me like you blew the rear main seal, way too high revs = way too high oil pressure, so the seal pops out. do you see seepage where the bellhousing meets the block? only way to be sure would be to drop the tranny, remove the clutch and flywheel and inspect the seal. they are an absolute nuisance if all your replacing is that seal. you might as well save up for a clutch/flywheel/driveshaft since your going to be in there anyway.
either way, i recommend replacing that seal asap, because it can leak oil on your clutch and make it slip.
the seal is about $12, you'll need some caliper grease or similar grease, and a drift pin that is a little wider than the width of the seal. remove the old seal carefully with a pick, clean the remaining pieces of the seal out, push the new seal on by hand and then take the drift pin and tap it in, going top,bottom,left,right; listen to the sound it makes when your tapping it, when you hear a metal "clink", its tapped in all the way and your done.
