Recently I have noticed that my oil light turns on when the car is at idle and at operating temperature. For example I will be sitting at a red light waiting for the green light and notice that all of the sudden my RPM drops a bit (from 800 to about ~600) and my oil light goes on. Sometimes it goes off and sometimes it just stays on until I began giving some gas and raising the RPM and the light goes off.

I have checked my oil level and I have the correct amount of oil. I am suspecting that maybe my bearing clearances have widened too much and I am losing oil pressure at idle, is that even possible or am I just talking crazy? The car/engine has 183,331 miles on it.

This is on a 5th Gen, H22 5spd Prelude.

Thanks,

 

its possible buy not likely, you oil pump gears may be getting worn out though. are there any other strange happenings?

 

my oil light comes on but it doesnt idle down like that, and i check the level and its fine! i would try changin the oil....oil light can mean loss of oil pressure...so changin it could help!...worked for me!
