Erg. When the hydro-EV cams were failing, they'd ruin the oil pump, too, in many cases, since the pump gets unfiltered oil. In really bad cases (enough schrapnel to clog the filter), or on bikes that were ridden cold a lot (cold oil often means the filter is in bypass mode) the rod bearings were ruined and the sludge trap was full of metal.
If that were my bike, I'd be pulling the crank and cleaning the trap and looking at the main bearings. The front main bearing is only sold as part of the crankcase, so you want to make sure it is undamaged while the bike is still under warranty. If it has metal embedded in it, make them replace the whole engine.
