How often has the oil been changed? regularly? as in every 3,000 miles?

you will find sludge particles floating around in the oil pan, these get
picked up in the oil pump's pickup screen little by little. then you find
a dropping or erratic oil pressure. most common is the dropping oil
pressure. If you find sludge your best course of action is to replace the
engine assy. the next best would be to clean the pan, replace the oil
pump and pickup tube then hope you can last a while before enough of the
sludge up top gets dislodged to start causing you problems again.
When i was working on cars i replaced more than a few engines for this

I've seen them leak into the plastic housing and after its warmed up good
give all kids of erratic/wrong readings before again this can be proven
with a visual inspection and mechanical oil pressure gauge.
