Hi everyone, looking for some help.
I'm a brand new Omega owner, so don't know anything about them. I've found 2 problems (so far  ) with the car.
I bought it in Liverpool and drove back up to Glasgow, the whole way up it was running very rough. I drove up the M6 at 70 the whole way, and the best way to describe it would be the engine was farting! It seemed to have power for 2 seconds, then less power for 2 seconds, then power up again, pretty much the whole way. Having said that it did make it all the way from Liverpool to Glasgow, but I want to get this sorted before it gets any worse. Would really appreciate any suggestions!
The other problem with it is the climate control, it looks as if it's working fine, but even with the temperature up max, it only blows out freezing cold air. I've checked all the fuses (about the limit of my technical knowledge) and they seem ok. I don't know if it has anything to do with it, but when I had the headlights on, all the buttons were illuminated on the dashboard except those on the climate control panel. I'm sure you can imagine in this weather, it wasn't fun driving all the way from Liverpool to Glasgow with no heating!
Any help you guys can give me would be very much appreciated.
Cheers
Allan

Paperclip it first and see if there`s any fault codes and post up

Here`s the link to replace your CC bulbs http://www.omegaowners.com/forum/YaBB.pl?num=1162120610

Try re-setting the CC. Press OFF and AUTO together for about 10secs, should here the flaps re-setting.

was this an e.bay car by any chance. hopefully not from a M. Southern?.

Rough running may well be the usual leaking cam covers...

Have a look and see if any of the spark plugs have oil in the plug wells...if so then your cam cover gaskets will need replacing and chances are the misfiring is as a result of the oil in the wells shorting out the plugs/leads and may have caused dispack failure...

Hi guys, thanks for the posts. I've done the paperclip test, and I'm not getting any faults coming up.

I know this sounds really silly, but whereabouts are the spark plugs? Complete car novice here!

It was an ebay purchase in fact, but not from an M Southern. I only paid £550 for it, so if a rough engine and faulty heating are the only problems I think I'll probably be quids in!

I've tried pressing auto and off together as suggested, I could hear some whirring going on, but still just cold air blasting out. I took it a run down the motorway and back to get the engine warmed up, the temperature guage was normal, but still no heat from the climate control

Allan,may not be relevent but take off the water bottle cap,start the car,put your demisters on full to screen only and leave it running for about 15 mins(obviously keep an eye on the temp gauge)

Just in case its a simple airlock in the system causing the problem...

Also, when it`s up to temp. check heater matrix pipes in driver`s footwell are getting hot

[AllanGlasgow]

Hi guys back again!

Right, I did as suggested and let it run for 15mins with the coolant tank cap off, still no heat coming out the heater, even after the car got up to temperature. I had a poke around the drivers footwell, I couldn't find any pipes down there, do I have to take the plastic trim off, or lift the carpet to find them? The general area was warm, but I couuldn't find where the heat was coming from. Definately not the demisters anyway!  

[Iain]

Daft question mate,but

Is there heat anywhere else?

i.e at the floor.......

[AllanGlasgow]

Nope, I've tried it on every setting, demisters, face level, floor level, combinations, automatic, manual, different temparatures, everything just blows out freezing.
Just a point though, when I was driving back from Liverpool, I had it switched off most of the time. After it had been switched off for a while, the air blowing through the open vents was lukewarm, but when I switched the blower on it turned freezing again. Don't know if that helps with the diagnosis... :-?

[unlucky alf]

if it was a old style heater as in non a/c i would say the heater matrix is blocked but i dont know anything about a/c, anyhow might be worth flushing out the matrix anyway & give it 50/50 water & antifreeze afterwards

[Iain]

Its probably going to be something more technical but,

You could try draining the coolant and flushing out the system, there is a 'how to somewhere',on here,could just be a blocked matrix.....

Back flush it....i.e stick a hose in the bottom Rad pipe and turn it on,just beware though dont do it too hard as the pressure could burst something....

Might be worth a try before you start getting into taking the dash apart etc

[Iain]

You type quicker than me Alf!

The other possibility is the thermostat...it could be jammed open or even missing,this would cause the coolant to be constantly circulating,not giving the matrix a proper chance to heat up...

These are all just stabs in the dark mate but i always say,start with the easy things first....

[Welung666]

When it's up to temp check the 2 heater hoses going through the bulkhead from the engine side, if they aren't hot then HBV if one is and one isn't then blocked matrix!

[AllanGlasgow]

Thanks again for the posts guys, unfortunately I'm now in the middle of a blizzard so I'll wait until tomorrow to check these things out.

Had a sudden awful thought though, could these be signs of the head gasket blowing?
