possible major problems with my lude

heard a few strange noises after coming home from work yesterday,then this morning when i started the car i just knew something didnt sound right
and now the following vid is how it sounds now.
i am hoping that its the crankshaft pulley as you can see a slight wobble off of it(this is the used one i got from Lude Dude) but its that noise thats puttin the shitters up me
possible bottom end damage?
HELP!!!!
listen to the vid and give me your thoughts please
cheers
