NOT Good....

Personally, I think you're smart pulling the engine to check it out. It makes it so much easier to work on when it's out of the car. At minimum pull the pan and main bearing caps for a look see.

What kind of oil filter were you using? Have you cut it open to see how much metal it caught? Hopefully it did not get totally clogged and allow unfiltered oil to circulate. This is a good reason to use a magnetic drain plug too.
