after starting engine, low pressure light turns off as it should,but after 1 or 2 seconds,the light flickers for just a split second, and light wont come on again until i stop the engine..its been a week now since i've noticed this. i opened the oil filler cap,oil was flowing good.just had 1000 miles on the new oil and filter.i've cleaned the oil pan a month ago. this oil light is bothering me.Is it a sign my oil pump is bad, or there are other problems? by the way,oil is castrol 10w30. temp.during the day never goes below 100 F. any help will be appreciated.

Check the oil pressure with a mechanical gauge,if normal replace the oil pressure switch/sensor. If abnormal could mean oil pump and engine bearing.

ok,tnx. i'll check for pressure after i find a gauge to buy.
also when i cleaned the oil pan last month, i tried shaking, pushing, pulling the con rods to see if clearance is bad.it would move only along the crankshaft,no movement up or down.i guess bearings are still fine.
