Hi

The engine warning light in my 2.2 2001 omega came on yesterday. I checked the oil and it smells of petrol. Does anyone know why this could be? Having googled it, I have got the following:

a split in the petrol pump gasket.
a leaky piston
compression adjustment
change oil and sell the **** thing 

Anything more definite before it costs me an arm and a leg to find the problem?

cheers

The oil is still the colour of used oil, a sort of browny black. The car had a full big service about 6 months ago with a complete oil change, since then the car has not used any significant amount of oil

pull each plug and see if any are wet with fuel shortly aftyer running the engine for a shortime, also check colour.

beware running the car with a bad injector could bugger that bore if the oil is too thinned on the cylinder wall.

Re hg do you have any coolent loss at all...?

not sure if the Omegas have a temperature sensor that signals the ECU(as well as the one for the guage) but if they fail it can cause this problem too.

As in water in radiator. No, checked that first as I had a head gasket blow a long time ago on a different car. The colour is fine too.

I have to borrow a plug spanner from somewhere before I can check the plugs, that should be easy (not).

I am really thankful for all the help you are giving me btw.

no worries,
would say your hg is fine then. couple of things

fill in your profile with your car details and rough location, it helps with diagnosis and saves people keep asking.

also try the paper clip test or pedal trick depending, for any fault codes, wont do any harm...link below

How would the engine's ECU know the engine temp if it didn't have a sensor? :-/ The ECU's engine temp sensor lives right next to the gauge's sensor.

Thanks, I will update my profile, light has gone off now, and someone on the vauxhall forum said it could just be that I do too many short journey. What do you think?
