Clean the plugs and put them back in, test the car with the code reader you got.
Also check the breathers for dirt and cam cover gasket for any oil leaking.
For the breathers it would be advisable to dismantle them and clean.
The butterfy valve can be pretty clear from the top view but on the underside it can be a mess. You have a great how to in the maintenance section.
Also for the consumption of 2.2 should be around 7.5 to 8 litres on open road and anywhere from 14 litres in town driving or even more on really short trips. This is mainly all due to the weight of the car.

:-(
  >:(seem to have a very big problem now 

right here goes :-(
told wife to keep a eye on the coolant as we having problems with loosing it from some where

seeing its so cold here right now and because of the coolant lose i needed to get more anti freeze but forgot :-(

anyway wife took it out for a spin but after 5mins in -10c the car was on red and the warning light came on!!!!!!!!!

i had a look and again mayo in the filler neck! and the water reservoir was bubbling and making noise ,after approx 2 hours i loosened it carefully and the pressure was still  very high  :-? :-? (even after all that time)

next i ensured that there was plenty of fluid in her restarted and let it get hot, it very quickly went to red hot/light on but then it dropped and stayed at 90c!!!!

antill i went for a 100m drive again went to red!!! and was kicking out lots and lots of exhaust flems,but once stopped it went back to 90c and held there

but the other thing is now it was hot ! i put the heating on and all that came out was ice cold air!!! even thought the car was hot!!!!

if not head gasket gone could there be either a air lock (seeing i have to keep topping the coolant up) or even seeing its so cold could the pipes in say the heater maxtric be frossen solid and in turn not letting fluid run round the engine!!! which in turn is making it get red hot ?

but would that course bubbles in the res? (or is that engine gas due to hgf ??)

cheers your replies will be helpfull
im off work saturday so will take breathers etc off and have a look i assume if there blocked with mayo that would be the best way to def no if hgf???

[mathewst]

Looks like you are loosing coolant on heater matrix probably which isn't working. Either it is heater matrix or HBV.
Heater matrix can be flushed (there was a how to also). No wonder the car got hot if it was town driving and not enough coolant

well a few items arrived today :-) (well yesterday lol)

got my cam cover gasket and thermostat

went out to change the theromstat + housing
removed the old one that was showing signs of leaking

as you can see the crust where its been leaking ,i would say for some time too!!!!
took the old thermostat out

took it out boiled it and nothing !!!! its def not working,did not open even at boiling piont
also who ever changed it last time just put loads of loctite on it which you can see even in the housing,bet it also gone in the engine :-(

anyway fitted the new one,no more dripping but the heating still not working,even the pipes going to the heater dont heat up !!! AIR LOCK MAYBE //

thing is ive read how to flush the heater but i have a problem there i live on a top floor flat 4 stories up so no chance of getting a hose pipe to the car anyone got any other ideas?

also whats the best way to bleed the system???
the car never got any higher than 90 on the temp gauge but like i say the heating was cold so i assume theres a air lock or blockage?

going to do the cam gasket tommorrow hopefully that will stop the misfire? if not the hbv should arrive hopfully tommorrow as well and the code reader

.....
also whats the best way to bleed the system??? ....

After you've initially filled it, run the engine, 'burp' any of the bigger hoses you can get your hands on and top up as required before it gets fully hot. It'll self bleed, any air in the system will make its way to the header, so just keep an eye on the level over the next day or so.

PS get those car bits off the kitchen sink before SWMBO sees them

[griff2494]

cheers for the reply

i assume that seeing the thermostat did not open /not work that could explain why she got so hot!
also the leak on the housing could be why the water loose,and once i change the hbv i assume then all routes are covered as for water loose as no pipes are split

[griff2494]

forgot to say, had a quick look while out at the car for the hbv thing,told it is at back of enginge near rockercover under the scuttle panel, but i cant see/feel it  am i looking in the right area??? am i right thinking my 2.2 should have one? could someone of taken it out and bypassed it some how????or is it just a idiot to find without taking the scuttle panel thing out(windscreen wiper plastic thiung i mean)

[Abiton]

I think all Omegas that have aircon have an HBV.  If you follow the matrix hoses from the bulkhead towards the front of the car, you should find the HBV, though access/visibility is 'orrible in that area.

If you do have one, the cold heater and coolant loss may both be solved after replacement.  I think one of the failure modes of the HBV will result in coolant getting to the underside of the vacuum diaphragm that actuates it.  This would tend to push the diaphragm up, as if the aircon were on, and the HBV would be diverting flow away from the matrix.

Good luck.

:-( hbv still not arrived :-(

the post out here in germany is crap!!! (well the army bfpo is lol)

[griff2494]

well just been out to brave the cold (-10 here :-( )
thought i would tackle the cam cover/rocker gasket

im sure someone before me must have done this before as the bolts where not tight! (not sure of the torque settings they should be but they where just tighter than finger tight)

anyway took it off to find this




i expected to see some mayo seeing i was told that is quite normal for a car of this age (2002) that just does short journeys,but not this much ! esp seeing when i did the breather pipes before they where covered to

but still theres no sign of mayo on the dip stick!!!!

ive looked down into the pots like was advised to ,to see if i could see any water/antifreeze on the pots after she had been ran then cold but i cant see any  :-? so still not sure if its the hg

whats everyones opion

cheers griff
ps next is to clean the mayo from the rocker cover then get it throw the dish washer  (while wifes shopping lol)

[griff2494]

now im even more confused!!!!!!!!!!!

when i started to clean the mayo out ,i turned the rocker cover on its end so the 2 breather pipe holes faced the table and this happened

water ran out of it all over the news paper  :-? :-? :-?
but i dont under stand
1. that much water!!!!
2. its clear water!!! has no antifreeze in it  :-? :-?
i had to get a bowl in the end

like i said thing is it has no antifreeze in it its clear  :-? :-?also how can it of got there????surly that much water if it was from hg the engine would not work and the rocker would be jammed packed with mayo
also does the rocker cover come apart? ie where the breathers are it looks like some kind of cover ,but i dare not start pulling at it incase it should not come apart

[mathewst]

Cam cover should be tightened at 8nm which is really low so it shouldn't be tight at all.

[Abiton]

Don't worry about the mayo and the water.

What many people don't appreciate is that when you burn hydrocarbons like petrol and diesel, the reaction produces primarily carbon dioxide and water.  The carbons combine with oxygen to form CO2, the hydrogens combine with oxygen to form H20.

This is why steam comes out of exhaust pipes (all the time, but usually only visible when the exhaust system is cold), and why crankcase ventilation fumes contain significant amounts of water/steam, via blowby past the piston rings.

If you only do short journeys, this moisture in the crankcase and breather system may build up, as the whole engine isn't hot enough for long enough to evaporate this stuff out.

And the reason why you should just drive the car rather than have it idling for ages ages on the drive.

well wife came back so could not use the dish washer :-(
but she was still pissed off when i took it in the shower pmsl

but much better know ,now mayo


,and also got all the crap out off the hard to reach places lol

all breather ports sorted,clean inside and out :-)
i used to have a vauxhall carlton and it had some kind of blocks of mesh in the rocker cover that acted as a filter they where so much easyier to clean than this set up on the omega
