I have to agree from what I've seen:
Most Common #4
I've never seen #3 - anyone?
Happened on all cylinders? I think what probably happened is that it dropped a valve seat on one cylinder and it kept going through the intake manifold and into other cylinders until it was obliverated. I know on my SPI, when it dropped #2, you can see that particles of the valve seat flew into cylinder #3 and #4 because there is some indentions on the right side of the piston. Cyl #1 is the only one that looks normal and had no valve seat particles fly in it.
Cylinder #3 dropped valve seat? Never heard of it, never seen it.
