Anyone know about a filter on the block other than our normal one we screw on and off during routine oil changes?

[lr172]

that's a pretty vague question. What kind: Oil, air, fuel, etc. I know there is an oil screen in the sump.

Yes, there is a finger screen on the oil pan that should be checked each oil change. It looks like a pipe plug along the bottom edge of the oil pan. On my engine it is at the bottom rear edge of the oil pan.

To add a bit , it should have a safety wire on the plug.
