Omega V6 cylinder head gaskets fail in one of two ways
1. coolant seeping through rotten gaskets and running down outside of engine
2. failure of 'fire ring' part of head gasket causing exhaust gases to blow into coolant passage when running (and coolant into combustion chamber when stopped)

If it is oil then it is weeping cam cover seals caused by blocked breathers pressurising the engine.

Right -thanks Andy - I'm quite sure it's oil that is leaking - but will double check that it wasn't coolant on the ground that I saw. I guess I should keep an eye now on the coolant level? If coolant was getting into the combustion chamber I'm guessing it wouldn't run very smoothly....

Hi Guys.  I think Ive got the same problem as the first poster.  I get the Car with a Spanner symbol appearing on the Dashboard.  I drive an 02 Auto 2.2.  I can reset it by turning the ignition off then on. The light then disapears, before reappearing when Ive been for a drive typically arounf town when im doing 30 MPH or so.  I wondered how easy it is to replace the sensor myself. Ive tried looking at the manuals on here to find photos or information, but  I can see anything? Is it a straight forward job, and would you recomend that I order the part from my VX garage? Thanks guys

Hi Richard

As advised by the helpful members on this forum - do the pedal test as decribed here: http://www.omegaowners.com/forum/YaBB.pl?num=1189022687

and report back what codes you have. It may not work on a 2.2 though - can't be sure of that.

Crank sensor replacement guide can be found here: http://www.omegaowners.com/forum/YaBB.pl?num=1174321688

Hi Koomorph!
Ive tried the pedal trick and it doesnt work. Ive just ordered a diagnostic code reader, so I will have to wait for that before I know the code.  Replacing the Crank sensor and the cable seems to be straight forward??

Oke Doke. Cam Sensor, is there a guide to that on here JimBob?  Just wandered out and had a quick look under the bonnet, and Ive got a small oil leak as well! Il upload a photo when i can work out how to do it  Would this be connected to the problem with the dashboard light?
Heres the photos of the oil leak

People have reported running on 4 or 5 cylinders immediately after starting.

Theoretically, if the quantity of coolant in the cylinder exceeds the combustion chamber volume at TDC then hydraulic lock could result in a bent conrod. The coolant loss and other mysterious cooling ailments usually become impossible to ignore before that stage is reached though.

looking at that picture you have a 2.2/2.0? There is a gasket at the bottom of that pipe, easily replaced.

Hi Tunnie,

Yes Ive got a 2.2 Auto on an 02 Plate.  Im sorry Im being a real daft so and so gents and ladies.  Any ideas what the part number is for the gasket?.  Do I need to take any special precautions when replacing it? ( Besides putting my brain in gear!) Just a question of unbolting the pipe, and taking the gasket out and then putting the new one in?

no idea on part number sorry, but when you replace and clean, do the whole breather system at the same time  :y

wait till your code reader arrives, and check the codes, but crank sensors on the 2.2 are fairly bullet proof, its the cam sensors that go. Mine went at around 100k, make sure you replace with genuine part.
