My beater / loaner may be nearly dead, and used up.
It has a little oil in the bilge, and the oil light with alarm goes off a few seconds after starting.
They remain on while the engine goes to limp mode, no power / rpm / speed above fast idle.
Starts just fine, with no new knocks and rattles. Oil level is topped up.
I hoping it's just a sensor issue, but don't know the check and fix proceedure.....

Time to fix & sell. Get a new somethin'.
