Oil light flickers when I stop at light and rpms go below 725. Oil level is full, but I also smell hot oil when it happens. I don't smell the oil any other time. Just had an oil flush and pressure tested before this happened. Everything ok. Just found answer here: Question: Why would oil pressure light come on when car is idling in park or in drive?? Answere from valleyautotech: You need to have a shop check the oil level and pressure as a mechanical oil pump has low pressure at idle then as the motor revs if gains pressure. If the screen on the oil pump is beginning to clog or the oil pump itself is beginning to fail it can do major internal engine damage if its not addressed,

I wonder if flushing the oil system dislodged debris which now be stuck under the oil pressure relieve valve. Why did you flush the system to begin with? Perhaps it would be worth just changing the oil pressure switch and oil filter and see if the problem goes away if not it would be important to recheck the oil pressure using a mechanical oil pressure gauge. If left un-attended major damage could/will occur.

Took to Firestone for brake problem and they said I needed complete brake overhaul which would cost close to $800 for that alone, but also had oil and coolant leaking into the engine, possible bad head gasket. got a second opinion from a more trustworthy source had brakes repaired and did the flush to test for the other problem (found nothing wrong), total cost under $400. But now this light problem. engine runs perfect. no overheating, runs at 206 degrees when hot. If debris was causing the problem, woudn't it there also be a problem at driving speeds? What kind of damage would happen, would it be accumulative or sudden? Just wondering if something would happen on the way to the mechanic, what to look for.
Low oil pressure light comes on intermittently and "stop engine" also. Oil level is ok & engine heat guage never rises above "normal". Can the sensor be bad & where is it located?
my oil pressure light comes on when my cars in idle but goes off when i drive i got a oil change and a diagnostics test and nothing came up what is it
when I am moving the oil light goes out . Either when accelerating or just coasting. when I stop at a light or to park the oil light comes on again. Could be head gasket huh?? Had oil changed and t...
