Ah - ha.....
Metal in the oil filter, cylinders missfiring - this sounds familiar, and I'll bet there's metal particles in your sump too.
Mike, ask your mechanic how he knows its main bearing metal and not big end bearing metal - they are both white metal plain bearings. He may or may not have put a magnet on the debris, but if the metal is ferrous, it could well be your IMS bearing assembly breaking up.
