Well, not firing the motor this weekend. As I'm pulling the crank around and setting valve lash, up pops a squirrel nest through the cam. Start digging it out, and somehow it is in the underside of #4 piston. Got the majority of it out. Came in the house. Told my wife about it and said I am going to try to fire it up Saturday afternoon. She says "are you nuts? You have too much money in that to take that kind of chance." This coming from someone who doesn't even know where to put the washer fluid. So, today, off comes the pan and scraper to see what else is left inside.
