Its definatly more of a rattle than a knock. And the weird thing was under
acceleration it didnt make too much noise but as soon as i back off its very
loud! I did tighten the pully back up and started it again but no luck.
Thats what made me think it was a main bearing. This weekend i'll pull the
pully off and swap it with another one and hope its just a snaped keyway.
I'll go thru the process that Andrew S suggested and hope its not a
bearing!! Thanks guys i'll get back to u when i find out more. Cheers
