Yesterday I put up a post regarding misfire 4. was advised to check plug holes for oil water etc. Appears to be dry so other possible solution is coil pack. Filled up cooling level as it appeared I was at it.  Was out in the car today small journey excessive exhaust fumes and coolent loss again. any ideas. Would the misfire contribute to this and should I go for a coil pack.

if you have no visible signs of coolant loss it could be your head gasket causing the fumes and missfire,do you have excessive pressure in the header tank?

[Welung666]

Not yet. A few checks to do first before spending out on a coilpack and finding out it isn't that.

Are you loosing coolant? If so, how much, how fast?
With the engine running are the radiator hoses getting really hard like they are pressurised?

Pull the plugs out and note the colour of each in turn and report back

No visible signs of coolant loss leaks etc

[Raymienets]

Only visible in expansion bottle.

When it's warm turn it off and squeeze the radiator pipes to see if they are really hard. Check them every 20 minutes to see if they soften up. If after an hour they are still rock hard then my best guess is that the fire ring between pot 4 and the main rear waterway has failed on the head gasket

[Raymienets]

Doesnt sound to healthy I suppose. Cost at its worst

To be honest dont know if pressure is excessive how do you tell?

The 2.2 has a known weak spot around no.4 cylinder & this is where the majority of HG failures occur. With the engine running, check for bubbles appearing in the coolant expansion bottle, also take the cap off & smell the coolant, does it smell of exhaust gas? Are your radiator hoses rock hard when the engine is up to temperature? Does the temperature gauge  indicate the car is running hotter than usual, or has it/is it overheating (red warning light on?)
Are there any signs of emulsified oil (mayonaisse) on the dipstick, or large amounts on the oil filler cap?
For a definitive check, Run the engine upto normal temperature or take it for a run before going to bed, let the car stand overnight then remove the Dis pack & no.4 plug (the one nearest the cabin). Then either shine a small bright torch into the combustion chamber & see if you can see any liquid there or firmly fasten a piece of absorbant material (cotton bud etc.) to something like a kebab stick or pencil & lower it into the combustion chamber making sure it reaches the  deepest part of the piston head & move it across from side to side before removing it & checking by sight & smell for signs of coolant. Repeat on the other cylinders if necessary.

Cheers will check it out tomorrow. never noticed any bubbles in expansion tank and is gauge is normal not going over halfway, but excessisve exhaust fumes.

Don't get too worried about the amount of 'smoke' coming from the exhaust. The 2.2 omega  has a large exhaust system  When the weather is cold as it is now, they chuck out a horrendous cloud that doesn't seem to get much less even when the car is warmed up! Nowt to worry about though unless you have any of the symptoms mentioned earlier or are losing coolant constantly & can't find the leak anywhere?

Yeah losing coolant constantly. Had to top it up again today.

You need to find where that coolant loss is coming from. It may still not be a HG failure, but you will have a clearer idea after doing the checks mentioned earlier. If no sign of coolant in the cylinder/s, then the next step is checking all water hoses & joints & especially the Heater Bypass Valve. :-/

No leaks visible not evan at HBV. hoses appear pressurised nothing in plug holes.

Loosing a lot expansion tank was only half full today.
