I changed the oil on my 1989 5.0 a few days ago and after about a half hour of driving, the check oil light came on. I checked the oil then and again later once the engine was cool and it looks fine. The oil pressure looks normal too but the light still stays on...

I've driving about another 20 minutes since then but it makes me really nervous given that I just had the engine rebuilt last summer, I need this engine to last me another decade or two

Any thoughts on why the light might be on?

Could be an issue with the sensor, or the wire got pulled off/damaged. Can you crawl under and have a look at the wire?

If you pull the dipstick and see it is full, I wouldn't worry too much. The check oil light is just the level sensor in the pan. I do not believe the oil pressure switch is tied to it at all.

Where do I look for the wire at? Must go to the oil pan some place I suppose.

Pass side of the oil pan. It travels down to the area via the O2 sensor harness which connects to the main engine harness under the MAF meter.

Well, it went off on its own when I went out to get my lunch... I'll look under the car if it comes back where you suggested. Thanks!

if you didnt fill the filter when you changed the oil, it could have momemtarily had some air trapped in it. I always fill the filter before installing
