Answer
Hi WR,

more likely it's the oil pump or could be the pickup valve in sump.  Here is a simple suggestion that may help:

drain oil
remove oil pan and thoroughly clean the area with a solvent and lots of rags.
Make sure pickup valve is clean; you could carefully clean this with a tiny hose brush.
replace oil pan, filter and oil.

Check the serpentive belt to make sure it's not slipping on any of the pulleys.

Best of luck,
