Hi,   We drained the oil today and some metal parts came out.  Looks like halves of some  flat spring washer of some sort.  Can anyone identify these parts?  Does this mean my engine is dead?  No other metal or grinding are present in the oil.  One of these pieces cam out on the magnetic drain plug.  I fished 3 more out with a magnet taped to the end of a wire.  Does that account for all of "them" or could there be more in there?  Photo attached.   My son needs to drive this back to Utah nex
