I have an oil pressure gauge in mine and have never seen a dip in pressure on a spirited drive.
Thanks Samm3y, i am going to at least drain the oil and see how bad it is first. If it is glitter fest, I am seriously thinking about taking it apart my self to investigate the extent of the damage. My concern is the risk involved in taking it apart and putting it back together incorrectly, or finding that the journals are scored and that it needs a new crank, which a shop would have to do.
