Plus one on Aristocrat. I've not been impressed. I talked to a guy at Rennen a couple of years ago who sounded reasonable. Then there's always Bob Hindson Racing
BHR Bob Hindson Racing, Inc. (No affiliation) I think he's an actual distributer for the LN bearing. Take and post pics of the rubber parts in your oil filter. It's probably leftover gasket material. I've had it before too.
