Omega General Help / Re: Anti-freeze smell in cabin and windows fog up

« on: 11 December 2006, 21:12:07 »

Thanks for the advise on the radweld - wasn't sure about that - will endeavour to strip down car to find the problem - I just wish it would stop raining!

Regarding the wheel balancing, meant tracking - sorry, I think I was a bit vague there. Need a seconfd opinion - unless any of you guys have ever had the tracking sorted out on your miggy?

Cheers

Omega General Help / Re: Anti-freeze smell in cabin and windows fog up

Ok, have checked but can't tell if I am loosing coolant - if I am then it is not vanishing quickly.
The front windscreen keeps misting up and so does the rear windscreen - there is also very little pressure in the expansion tank. I am thinking a slight leak in the heater matrix - think I might try some bars-leaks to see if it solves it. If I put the heater on and point it to the windscreen, there definately seems to be water on the screen - steam? The smell is really bad - just like when the water leaks if you split a pipe or the rad.

Does anyone know if bars-leaks will solve matrix problems? There is NO leakage in the footwells.

Now here is another question - the car seems to skip across the road on the front and possible the back too. I went to kwik-fit to get the wheels balanced, but they said it was main dealer only as they had to fit 140KG weights in the two footwells to balance them - is this right? A new one on me....

Think the gas leaks and it can take up to 20 miles before I can put the gas on - maybe incorrect heating setting on the gas and also gas filter failure.

Any help would be appreciated.

Guys,

am I right in saying that if my moter is not one of those lucky enough to have aircon then I won't be able to find the HBV? Just a thought as have spent ages pouring over the bonnet trying to locate said device....

Hi all,

many thanks for all the tips and ideas - yesterday I backwashed the system with a hosepipe, but didn't get a chance to test it, so will be going to Nottingham shortly. Will try it then. Will let you know how I get on. Just a quicky, what is a HBV? and where is it?

will keep everyone posted.

Cheers

Omega General Help / Anti-freeze smell in cabin and windows fog up

« on: 09 December 2006, 13:06:45 »

Hi all,

Well, at long last, I fainally got the Omega on the road. That's the good news. The other good news is that the LPG works!

Bad news - there is a very bad smell of water/anti-freeze inside the cabbin and the windows steam up. The carpets are bone dry so can't really see the matrix being at fault. Not a major amount of pressure in the water system either. Car seems to run fine, but EML came on (after I had fixed the bloody thing) - confident a knock sensor fault - will be resetting system and then re-checking it shortly.

Please, if anyone can come up with an idea, I would be really grateful. Finally thought I had got a decent car - then this. BTW the temperature stays around 93 when driving through town, but fluctuates between 92 and 96 otherwise. Not tried motorway or traffic yet, so will keep an eye on it. Just about to go and fluch the system - that is going to be interesting on the side of a busy road!

Cheers for you help

Hi folks,

Thanks for coming back to me and not giving up!

Not had a chance to try it on Gas yet Markjay, will be doing so when the car is road legal (hopefully next week). Will change the fuel filter as matter of course I think.

With regards to the fuel vent, I have found the cover in the boot, but the gas bottle is well and truly bolted down on top of it! The thought of having to unbolt and move the cannister before playing in that area fills me with dread, but as there is no light on at the mo, I am oing to keep an eye on it and see if one is not tied in with the idea.

Watch this space - and thanks again for all your help.

Ok folks, an update!

After sitting on my arse for a few days, reading everything I can find, listening to you guys and dissecting an old TIS that I found (from a previous Vectra that I owned a few years ago) I discovered all I could about this knock sensor.

So I waited for it to stop raining and reset the ECU by dropping the battery for 24 hours and then turning ignition on until all lights (except the EML) go out then turning it off 30 times (without starting it). I had a fiddle and couldn't work out where the cable to the knock sensor went. I d/c the ECU (after dropping the battery again) and reseated it. I pulled gently on the sensor cable and then pushed that lovely (sic) protection plastic over it - and guess what?

It worked! Light off, revved the nuts off it, no light! Took it for a spin - perfect! No missing or hissy fits! Not tackled a hill yet tho... Next week will be attempting that I hope.

Right, found that the clutch is hydraulic - a surprise as I had no idea they weren't cable driven. Got to get it bled I think, may solve the problem. Optionally I have been told that the clutch pedal may be on a ratchet system that auto adjusts and may need re-adjusting in the footwell - not sure about that!

Not much more to do then I hope we will be home free!

Watch this space for the next series of the Andiman bursting into tears and rocking in the corner, dribbling over more financial outlay!

Cheers

Ken, thanks for that info - getting darkish and wet here so will attempt to tackle / check those tomorrow.

Martin, interesting idea - hadn't thought of that at all. What do you think are the chances of the fuel filter causing the cut-out / power-down going up-hill? Am still going to check the otehr things mentioned by the guys on here as well. Is the fuel filter easy to get to and easy to replace?

Cheers

Sounds interesting...

However, don't currently have a copy of the Haynes manual, so really don't know

1. How to access the fuel tank - is there access through the boot or the back seat?
2. Where the knock sensor actually is.

can anyone shed any light on these for me?

I have found info on the fuel valve which states that either cleaning the contacts or buying a new one repairs the problem (!!!) - hte former would be preferable at the mo as am skint!

Cheers to all

Update to my last post -

Just realised that this car runs the Motronic as it is the 8V - so I now know what the 135 is - it says the EML light is not working! HA HA that is like the old PC joke on startup - no keyboard present, press f1 to continue!


Question, I think TheBoy is right, the knock sensor is either playing up, knackered or not plugged - but how do I totally reset the ECU to clear all faults and start again?

Appreciate the input so far guys

I agree!

The bulb was missing - replaced it with the headlight bulb.

Did the test.

Oh fun!

16

135

61


Found 16 - knock sensor signal circuit fault (what the hell is that?) - I know what the knock sensor is, but reading no voltage change  

135 - not a clue!

61 - Fuel tank vent valve low voltage - not a clue.

BTW now the computer isn't working! Never had a radio in it when I got it, so computer side doesn't work, but now no date or time!

ARSE!

Nice one guys,

Am now armed with a toolkit and some butter knives - and a missus howling "No, no, it is fine, leave it alone' - she has so much faith in me  

Will be back on here shotly - will swap the bulb out with the dash headlight bulb - don't need that one for the moment. Never got spare bulbs when you need them  

Be back shortly.

Cheers

Thanks for that Bo Bo, will go and have a play in a few minutes. Question.... is it best to drop the power to the battery to do this as I know on Vectras the airbag warning light can come on and stay on otherwise.

I am thinking this would be wise to do anyway?

cheers

Hi folks,

firstly, many thanks for coming back so quickly.

I have just spoken to the previous owner who has lost the security code/carpass info - so have spoken to Vauxhall and they will furnish me a copy at the extremely generous' (sic) price of 20 quid. Gee, thanks Vauxhall!

Moving on, there appears to be no clutch slip - the engine doesn't race at all. The brakes feel fine and I must admit having only had the car dropped off late last night I haven't had chance to do any more than start it this morning - it started first turn of the key, so quite impressed there.

Oh and the sunroof reprogrammed perfectly - so more good news.

With regards to TheBoy's comment about the keyfob - total agreement with you there, the one I have bought is the type that integrates with a key - and won't play ball at all! Bugger!  

The exhaust does not appear to be leaking - very quiet. No noticable loss of fluid under the car, but will check under the bonnet shortly.

Right, the management light.
This appears to have taken a long and much wanted holiday. No evidence of the bulb lighting up at any time - as I said previously, am very fond of Vauxhalls, so know that it should light on and just before engine start, but it is noticable by its absence. Possible bulb blown - or something more mysterious - ie removed. Hope only bulb blown, need to strip the dashboard out - anyone know how to do that? Done it on a '96 Vectra before, but unsure about this car as am always worried about the airbags.

Will check the breather system - the rocker cover has leaked oil out and this is apparent on the engine and a small amount on the gearbox from this leak. Highly suspicious of blocked air throughway.

Any other ideas?

Cheers

Andi

Omega General Help / Can anyone shed some light on this weird fault?

« on: 17 November 2006, 09:25:23 »

Hello all,

As promised (in the new members section) I am requesting someone's knowledge and ideas on a problem I have. Please please please someone shed a bit of light on this one?

Ok, have been looking for an Omega for some time now, always been into my Vauxhalls, and found a different one the other day.

It is an N reg (1996) Omega 2.0 Select petrol with LPG conversion on it. No tax, but MOT until July next year. At £400 I snapped it up - totally skinted me, but couldn't afford to turn it down.

Have only driven it once, but that was enough for me. I noticed this problem at the time, but figured that it should be curable. However now I think  need a few clues.

Right, the clutch takes right at the top of the peddle, so thinking either new clutch or cable needs adjusting - will be looking into that later. Not a problem.

No water / mayo in the header tank, on the dipstick, or under the filler cap. All fine there. Header tank holds pressure and car gets warm. Not seen if it overheats at all, but when you first turn the blower on, faint smell of old water.antifreeze blows out of the vents for a couple of seconds or so then it settles down. Odd, but not horrendous.

Enough waffling, down to the problem. The stupid thing hates loathes and detests hills. It loses power - to the point where you have to drop it into first and floor it to get up them. This is only in petrol mode - the gas needs a refill so not had chance to test that yet. Never come across this problem before, so was wondering if it could be the cat? No other ideas.

The engine (which has done 182000 miles) purrs and is so quiet in the cabin. The gearbox is still solid - most cars at that sort of mileage have a gearstick that feels like you are stirring porridge, but this is excellent so no wear as such on the brushes. the gas appears to be ok, but as previously stated, not tested that yet. All electrics are working except the sunroof - but I think it needs reprogramming. Found that bit in the book! Got to program up  a remote keyfob that should arrive today (tenner off ebay!)

So may have a dud, or it may be a good one - hopefully a good one as generally don't have much luck on cars.

If anyone could come up with any ideas, I will be indebted to them.

cheers

Andi
