For the last month or so, my 94 Sable, after it runs for about an hour, the
oil warning light blinks when at idle, it does not completely turns on. If I
press the gas pedal just slightly it goes off. Does this mean the oil pump
is not working properly? Is this enough to mess up the engine? If I stop the
car for 5 minutes it or so, when I start it again the light doesn't blink.
It has to be completely warm for it to happen.

Thank you

The pump is working fine, it's probably excessive bearing tolerances...
the engine is on the way out. How many miles? Last oil change? Dino
or Synthetic? Ever have a cooling problem (Head Gaskets...!) resulting
in coolant mixed in with the oil? The 3.8 is very prone to trouble...

Not knowing anything else on your specific situation, I would suspect oil
contamination from coolant, resulting in viscosity breakdown...when was the
last time you changed your oil? Have you been adding a lot of coolant to
the expansion tank of late?

The next two answer where right on the money I am pretty sure. I removed the
oil pan and the bearings were damaged. I also know that when I bought the
car used they had just changed the head gasket. It's very likely that
antifrezer did mix with the oil. Will replacing the rod bearings fix the
problem?
Thank you for your answers.
