Once warmed up, what is the temp gauge showing?

Just run the engine up to temperature and its around 92 deg max.
Ok, that sounds pretty normal... lazy thermostat and consequent cool running kills the fuel economy, but, that said with the lower temps lately... does the 2.2 have a separate ECU temp sensor?

Not sure. How can I tell?

Yep

Rear of engine by EGR. One sensor for the dash gauge, t`other for coolant temp.
Rear of 2.0ltr in pic, 2.2 same minus the DISPACK
All that is necessary for the triumph of evil is that good men do nothing.

Nice one Rob. Do you know if "My Naff Code Reader" software will be able to tell me if the ECU temp gage is working correct?

It should raise a code... P0115 iirc ;)

Won't solve the crankcase pressure, but might help the economy...

Thanks Al, I'll borrow a laptop in the week and see what comes up.

Do you know how much crankcase pressure is acceptable if any?

Can't help there :-[ There will always be some pressure, but a lot of variables once time and wear are factored in...

Whats the mileage of the car and has it ever had a head gasket replaced  :y

Head gasket failing won't pressurise the crank case.

Is the cam timing OK?

Oil consumption up?

The mileage is 115000 and I don't know if the head gasket has ever been done.

Is the cam timing OK? Checked the timing this morning and all is still aligned correctly.

Oil consumption up? No. It hasn't used any oil at all.

Is there a PCV valve on my 2.2 petrol 2003 and where will I find it?

Thanks
