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???

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

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

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. 

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)

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

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