Oil light flicker

thanson_mopar said

my old 72 dart with a 318 did it and my 74 duster did it before the light burned out, my cousinns 73 swingers does it when it warms up so it must be common. Oil pressure drops when warmed up and idiot light sees it as a problem, but i never had any problems with the oiling system

The oil preasure light switch on most autos is set to turn the light on at 7 PSI!
You need to put a good quality mechanical oil preasure gauge on it to determine if it is a faulty dash light or low oil preasure. My guess is very low oil preasure do to excess bearing clearance or wear.
