Omega 2.5TD elite loads of smoke & gutless
« on: 28 October 2007, 14:06:26 »

Last night started 2.5TD elite ,took ages to catch on then loads of black smoke had to rev hard to keep going sounded like there was a million nuts & bolts in engine...no power ...just managed to get us up hills. Started this morning....just same problem. Car done alot of miles had new glow plugs / diesel filter/ oil change/filter. No warning lights showing does not improve when warm. cannot drive in this state. Swapped airflow meter ( from my other TD) no joy. Swapped computer ( from other TD) no joy but it brought the EML on flashing We had a problem starting it last week & paid £222 to have coil heaters replaced + diesel magiced solved the starting but engine very gutless, was going to get the car checked for fault codes until this happened Once started u have to rev like hell to keep it running and it only just moves. I am fairly sure the engine does not use oil or water. Please advise as I am a my wits end with it.
How easy is an engine swap? thinking of putting the 2.5TD from my GL 2.5TD into it Will all the sensors cables fit ( elite)

Oh fubar....

sounds like the chain may have slipped  :'(.

How many miles has it done, and how often the oil changed?

Hi wait for it........... The speedo says , but no history whatsoever and the interior seems too good  for.........315,000 The oil and filter were changed 100 miles ago. At 8.30 last night it ran as it had been doing,low on power Ok on start up at 11.30  it was horrendous! I had put some redex diesel clean in full tank 50 miles ago

At 315k, I guess even if the oil has been done every 4.5k max, the chains are going to be pretty knackered.

Problem is, to change the chains, officially, is a head off and sump off job.  Whether of not that is necessary I wouldn't like to say.

Might be worth checking the cam and pump timing, but if its got worse suddenly, something drastic has happened (ie chain jumped)...

I need to get that timing cover off the old engine to see how easy it work be.

Chains, sockets, guides etc come in, iirc, at about £250 - £300 so engine swap may prove better as long as the donor is a good 'un  :-[

About 2 long days work I reckon to swap engine, and the A/C will need regassing afterwards.

Been there, done that. Twice.

Hey thanks for the advice.........the timing /chain slip makes sense as it did get suddenly alot worse.......what would the symptoms of a dicky diesel pump be as up until yesterday it was not running very well in that it struggled to do over 70 and was gutless.... What I am concerned about is if I swap the engine from my other Omega 2.5 GLS 150,000 miles I might still end up with problems if it is the the diesel pump ( I am assuming it is in the tank!)
Also how big a job is the engine swap ( from GLS to elite spec) will I still get all the bells and whistles and will the cables fit
If it is the diesel pump how easy is it to pehaps just swp the pump from the GLS?
If I can trailer the elite to get it checked out electonically will it tell us what is wrong with it. I am not getting an engine warning light even though it is nackered!

wont get an eml lit cos the ecu dont know the chai is stretched :-/ as far as its concerned its sending all the right signals!!! as long as the cars a re a similar year it will all plug together, but ithere are some differnces in early and late management systems, pump in tank is easy to change but i would think it struggled to et over 70 due to the timing being miles out to be honest, dicky pump usually means hard to start when stood ovwernight etc

Thanks Omegatoy...... you are helping me make the right choice here
The GLSis an S reg and the Elite an R. just a point... I tried swaping the computers....the part numbers were the same. When I did neither car would start and the eml lights flashed. I did the same with the air volume unit and it had no effect on the elite......but it cured an intermittant eml light flashing and restored the power to the GLS!!!! which was the reason I got a bit fed up with it and chanced my arm on the much higher specked elite....which I really like.....but I had a feeling in my bones that I was taking a chance with it even though it seemed to perform OK on the long test drive I gave it. Its the ist time in buying cars that  have trusted to luck .....and the last time!! I just got seduced by the leather seats and nice spec ( 50 next year and never had leather seats) Now I,ve got a nice car that won,t go anywhere!!   315,000 miles I must have been mad!
Is it easier to swap both the engine and box, ( they are both manual) and do they swing out in one lump?

Is it easier to swap both the engine and box, ( they are both manual) and do they swing out in one lump?

imobilsor wont allow them to be swapped and start with a reprogram it would have done :y same numbers then you can do it definetly!!! engine and box in one lump is always the easiest way and quickest!!! ask the boy!!!  if they
both the same car tho why not swap all the toys into your good one? or is the body not as good?? a weekends work will see the engine and box swapped but if you havent done one before allow more time so you dont make a cockup, :y
inlet wil probably have to come off to allow access to the oil cooler pipes, and the awkard one is the hydraulic clutch connection but its all doable, aircon pipes as mentioned will have to be disconnected so you will  lose the gas,  only other thing  would mention is how old is the clutch in the one your goig to use? cos it may be worthwhile replacing while you at it then you dont have to remove the box later on!!

Hi , yes the body & colour of the elite is better than the GLS, plus its got a functioning electic sunroof The thought of swapping all the bits and pieces to bring it up to Elite spec is a bit daunting....
Complete leather interior, electric seats
all electric windows
different better interior lights
better dash with electronic aircon
xenon lights
music system matching carpets
self leveling suspension ( but dont think it works)
Passenger airbag
I would have thought that I would have to put a new loom in? would that be the case?
A weekend to swap the engine & box just seems a bit more straight forward. BUT I am moving a good engine into a body and mechanicals that have done 315,000  vs 150,000!

As Omegatoy hinted at, take the box out attached to engine. So much quicker!

If both ECUs are the same type, use the Elite one to prevent problems with immobiliser.

Last time I swapped engine (with LFF64's help), we started about 11am, swapped engine, and had it bolted back in by 8pm, leaving a few hours to bolt back on the ancillaries.  I reckon I could do in a (very long) day now.  First time you do it, I reckon it will be a very long weekend as you have to work out what needs to come off, and how...
