Oil pump screen on Ford 4L OHV clogged. Can I backflush through the filter baseplate by using air pressure andor solvent?

If conditions in the crankcase have become so bad that the oil pickup screen is clogged, you have more of a problem than just a clogged screen. If someone has poured sawdust or other trash into the crankcase you MIGHT be able to pull the pan and clean the screen. If it's clogged for any other reason, you'll need to rebuild the engine.
