Hi all
right first off im new here (first post)

i went and bought a 2002 omega sport 2.2 today,got it at a very good price as the sellar has just had enought of it lol (spent £1800 since Aug!!!!! on suspension,track rod ends and full exhaust etc ect)

when i saw the car she told me that its got another problem and shes just had enought!

right heres the probs !

1. she told me that it seems to loose coolant with no signs of coolant dropping
i checked the oil/coolant with only very slight mayo in the filler cap,but her hubby does very short journeys approx 5 miles aday and thats it,so hopefully its the short journey thing?
so anyone any ideas???

2.  the light came on while driving home that looks like a engine,the book says emissions/exhaust, and it seems to be kicking out lots of crap
any ideas? maybe the lamba sensor??

3. Also the temp gauge ! it goes upto 80c then drops back to 0 then back to 80c ,any ideas? loose wire?

 ive done a bit of looking on coolant leakage and people have posted the HBV ?? what is this??? i assume thats NOT a dif name for hg ?

also  forgot to say it also seems to judder sometimes when setting off,but then runs stop of ,drove 200 miles home with it at 70mph and it ran spot on

so any help in this would be great

cheers
griff
ps do they have coil packs? maybe breaking down?

You will need to get the codes read to determine why the EML is coming on.
Temp gauge problem related to coolant loss.
HBV= Heater Bypass Valve and very prone to leaking. Check this first.

Welcome to the forum
HBV is Heater Bypass Valve. Not sure exactly where is on a 4 cylinder car, but it's at the back my block towards the driver's side. If you think Star ship Enterprise you'll recognise it when you see it. 

[griff2494]

wow cheers for the quick replies :-)
will look for that valve first ! would be nice if thats all the coolant lose was (hopefully)

as for codes being read i have no reader :-( would it be worth me getting one? if so what /wheres the best to get? (below £100)

cheers

This may give you an idea of what your looking for.

Evening and welcome.

A bit of mayo is normal, lots is not.
HBV Heater Bypass Valve lives at back of engine and controls coolant flow into the heater matrix.
HBV is the most likely source of mysterious coolant leaks.
Temp gauge could be a loose connection on the sensor, or possibly the instrument cluster is not quite seated right, give it a firm push into the dash. If the wire from the sensor is earthed the gauge should read full.
2.2's can suffer from head gasket leaks. Doubtless someone better informed will be along shortly.

if it was to turn out to be a hg problem (fingers crossed not) how big a job are they?

i just changed the one on my classic mini (its a convert mini lol has a 1.8vvc engine in it)

which was not that bad ,has twin cams/belts so would it be harder than that? (does the omega have belt or chain?)

[05omegav6]

[Kneepad]

it is unlikely to be your HG, difficulty depends on how good you are with spanners and how well equipped you are to do the job.
All Omegas have belts except for the diesels which have chain.

If you're capable of making a pot of tea, heating a pan of beans without them sticking to the bottom & toasting two slices of bread without burning them (all simultaneously of course ) then you are more than capable of doing a head gasket on a Desmond (2.2). The v6 is harder, you need to be able to do the above whilst simultaneously making & eating a thai green curry!

thanks everyone

this seems a brill place for knowledge :-)

the links are spot on thanks :-)

Fingers crossed that it is the HBV.

Short runs and cold weather will cause clouds of water vapour out of the exhaust but if the engine is 'lumpy' when first started I would check the spark plugs to see that they are all the same colour (if one looks like it has been steam cleaned you might have an issue with the HG)

Hi and welcome to OOF

If you post your location there may be someone with the correct equipment to read codes and perhaps look at live data etc .
When my HBV went i saw a drip of water when looking from behind drivers side front wheel and looking up .
Was dripping over gearbox ... not much but thats where i saw it

Your in the right place for help
