oil light
 

I have a 92' Prelude with a JDM DOHC F22B swap. The motor has 2,500 km on it and runs fine.

My oil light keeps coming on when I am idling. It doesn't come on fully illuminated though. It is very dim and goes away when i give it a little throttle. I had this problem last year when i fried my old F22B motor. So when I rebuilt the one that is in the car now. I changed the oil pump, water pump etc.. Everything on the motor is brand new except the sensors. But my car does not throw any codes what so ever. A friend of mine thinks it could be because my idle is too low. The car idles at about 700 RPM, but its hard to tell on the gauge. I havent tried turning it up yet because the problem started today, and its dark out. I am going to do it tomorrow.

I was just wondering if anyone on the board has ever heard of, or had this problem before. Any suggestions would be greatly appreciated. Thanks Mike.

Whats up with the funny looking gaylude as your avatar. Yea I had the oil light keep coming on, ended up being the oil pump >:(.

- I checked under the car and there is no signs of any leaks.
- My oil pan is dent free, and I personally installed the oil pick up. I check for clogging and dents when I rebuilt the motor 2,500 kms ago. It was working fine when installed.
- I checked the oil pressure switch with a multimeter, and It is fine.
- I checked the oil level and topped it up.
- And i turned my idle up to about 950 RPM

The light has gone away. So I took it for a half hour drive. And everything seems OK. No oil light. I am changing the pressure switch anyways, just in case. They are only $50.

I'd keep the $50 and I'd instead borrow a gauge and actually see what the pressure is, instead of hoping there isn't a problem. there are other things that cause the oil light to come on besides the ones you mentioned.

every car i've seen that the oil light flickered on at idle was becasue the oil pressure was starting to drop off from worn bearings that slowly fucked everything else up as they kept dicintigrating. revs hid the problem by rasing the pressure above the warning light setpoint

I have an oil pressure gauge. I am waiting on a dual outlet 1/8 Britsh thread to 1/8 Natiuon thread reducer, so i can hook it up. I think I'm gunna hold off on driving it untill i get the coupling. Does anyone have any idea what the oil pressure should be at different RPM ranges?

I'm usually running 12-14psi at idle, and my motor has a 140k on the motor. (F22B1) I'm using 10w - 40. What are you running? Type?

10W 40 full synthetic. I get the oil from Honda
