Y188NFA 2.2 petrol manual 84333 miles on clock
Oil light comes on at idle when hot. Goes out when revved. Worrying. I have had this before on older cars, usually sign of worn oil pump and/or bearings. Not on a young Omega, surely? Do the sensors play up?

[henryd]

For the sake of a few quid its probably worth replacing the sensor first but it could be the oil strainer in the sump partially blocked or of course the pump failing as a worst case scenario

Thanks, Henryd. Do you know where the oil pressure sensor is?

Not a clue Terry ,one of the 4 potters will be along shortly I expect(where is RobG with a picture when he's needed )

[terry paget]

Haynes does mention it, gives the job 2 spanners and no pictures. It's somewhere at the front of the engine, apparently screwed into the rear of the oil pump housing on 2 litre engines. A picture would be appreciated!

It could be the oil pressure relief valve,needs a clean.

[terry paget]

Agreed. Haynes does not mention the oil pressure relief valve in the index. Does anyone know where it is? Is there a how to guide?
