try maintainance guide on this site  2 inputs on changing gasket

It is pretty easy to do it. There is a maintenance guide for it I just followed it and it took me max 1 hour. Once you know how to clean the throttle body it is really simple to do it!

Here is the relevant guide: http://www.omegaowners.com/forum/YaBB.pl?num=1152565472

Note: if your spark wells are filled up with oil it does not neccesarily means that you have to change the cam cover seal. Make sure that it is really the seal and not oil from filling it up. If the oil is clean than it is not the seal.

[size=14][/size]The cam gasket was gone, have done this plus as i said cleaned out all the breathers ,the throttle body and yes unplugged the small hole, what i did find was the breather pipe to the block was distorted i had been getting an oil drip and after fitting new gasket not cured it ,so i took it off again put a straight edge across you could drive a bus through the gap so i got it on a thick plate of glass and ground it flat . No more oil leaks from there. I am buying a new coil pack as the old one is falling to peices must be the oil and heat. Still same LOW tick over 600 revs will see what new coil pack does. Oh yes i did change the plugs for new ones cheers Tony[size=14][/size]

Hope that you manage to sort your running problems when you fit your new coil pack!  Was your DBW throttle valve filthy??  I could not believe how bad mine was!!!

Did you manage to get to the bottom of the noise on start up??  Was it the exhaust manifold gasket??

Mine ticks over at about 600rpm.

Suspect coilpack for misfire, if been in oil.

Yes 600rpm for a 2.2 is norm.....might rise slightly with ac on and in N or P, but will drop down 600rpm as soon as D is selected if an auto  

I agree with AA....coilpacks dont seem to last long....they start to give a weak spark....esp noticeable if you try to run on lpg!

We are starting to see a lot of failed CPP modules, seems the old DIS/lead setup was equally, if not more, reliable.

[size=14]Many thanks every one for your input, I know it sounds a bit strange but i am sure the noice is from the EGR valve  [smiley=undecided.gif] i have had my head stuck under the bonnet every time i start it and there is a phutting noice coming from there, any one else had this. Re the coil pack i have had to put the old one back on until the new one comes. Like you all have said the rubber or plastic is falling to bits every time i touch it, so fingers crossed. I am steadly getting things sorted and hope i will end up with a decent car. I am thinking of buying two of the early mirrors though as mine is a 2002 model and a new one for the N/S is £200 a S/H one £100, missed one at £50 but i can pick up a pair of early ones for £25. I will have to see how to put a picture of the car on. I paid £1700 for it apart from the mirror the bodywork is excellent as is the interior it is the CD model and full service history,mind you what i have had to change and sort out it makes you think what they do for the money. It has had a new cam belt and exhausts from cat back. I dont think it was a bad price 100470 miles [/size]

[size=14][/size]RE- my 2.2 litre omega 2002 CD Auto -rough idle and if i set of at low revs seems to hesitate, if i put my foot down every thing is OK. I have put the new coil pack on ,not really made a lot of difference, so up to press i have cleaned out the throttle body like new now, all the breathers, new plugs Denso twin electrodes, new coil pack, rocker cover gasket, plus i have had it  on the top of the range diagnostic machine,  every thing is reading OK. It turns out the low revs at idle is OK the rev counter is out when put on the diagnostic machine it is ticking over at 730 revs and as i have said there are no faults showing up in any way. But even the technician said it sounded a bit rough on idle even though every thing reads OK. And i must admit i was there when he plugged it in , he showed me all the readings and levels spent a good 1/2 hr and it  still showed no faults. I will be honest don't really know where to go from here as i was expecting  some thing showing up. I expect it could be me expecting to much as i have always had classic cars, which i tuned myself and without being big headed always got them like sewing machines. These modern cars you can do b----- all with cheers bash
PS does anyone know where you get a workshop manual for the 2.2 litre 2002 omega from cannot find one anywhere [size=14][/size][size=14][/size]
