Could anybody tell me if the 2.6 is any diffrent from th e2.5, also is there any reliable diffrences?
Seen a couple of 2.6's but not sure of if there are any known problems with these and performance diffrences in comparison.
Cheers :)
-
I'm sure you'll get a more detailed answer from the more knowledgable ..... 2.6 has drive-by-wire throttle & no HT leads with coil packs for 1 3 & 5 and 2 4 & 6 instead of the DIS pack on the 2.5, no EGR valve, no secondary air pump gubins. And another 100cc! ;) :y
-
for me, 2.6 all day long. Pedal trick gives more accurate engine codes, no egr, no dis pac and leads(coil pac cylinder) drive by wire throttle. More refined sorted motor, will probably be newer/less miles. BUT, they do suffer with a pre cat problem which is of no real consequence other than the dash light on all the time, which may mask a more serious issue. Can be sorted by moving the lambda sensor, post cats, or something like that. Hth
-
2.5 was on pre facelift and FL, 2.6 only FL but u can take better MPG from 2.6
-
So with this pre Cat pron, what is likely to go wrong if its masking a bigger problem?
2.6's seem to have lesser milage and theres one local ish in gold im very intrested in.

Could do with the experience to buy my first Mig and keep her reliable.
Might ring him up if all is good?
-
looks tidy, couple of things, whats that black blob on the dash between the light switch and wiper stalk in the interior pic. Brake pedal rubber looks brand new. Mine has 70k and is almost showing the metal underneath. No reverseing sensors, may have been an option? And is that a removeable tow bar hiding under the rear bumper?
Cat issue itself is not a real problem. Its the engine management light constantly on thats the issue, annoying, and, if any other engine management problems arise you will not instantly be aware of it as the light will be already on. But regular pedal tricks can leds an eye on it. See here,
http://www.omegaowners.com/forum/YaBB.pl?num=1189022687
You can do the test on the car when you go see it. But bare in mine they could be old error codes stored. Codes translated here,

Hth.
Ps check all the dash lights light up when you turn the ignition on. Some times eml issues are hidden buy removing the bulb, in which case the pedal trick wont work anyway as the missing bulb wont flash.
-
Thanks for the help there , yes now you mension it there are a few bits like the pedal rubber and the dash blob, it does look clean but would it be best to buy private as the traders all seem to be over priced.
-
If you are concerned that the Emissions light problem would mask another problem, then you can buy cheap equipment to turn the light off.. :)
Vary from £30 for the ELM 327 to £80 for the Maxscan .. to a few thousand for a "real" Tech2 !!
I have the 3.2 which has the same problem, but the light has only come on twice in 11 months. A quick check, using the "pedal trick" confirms what the problem is, so I drive home and use the kit to put the light out until the next time.
The reason I have both is simple (like me) .. I bought the ELM 327 initially, it needs a laptop to make it work and is limited in what it does. As I like to know/do more I bought the maxscan, which I find better.
HTH
:)
-
Yes, private if possible, depends what available and how much of a rush you are. Private sellers tend, i always imagine, to want to get rid for fuel tax or repair issues and assume the car's not worth much. Traders know a little better, but regardless, will stick £500 minimum on any costs they incur. Hth

2.6 is fine, except for a bad batch of valve seals which leak
-
Are the 2.6 in the Omega same with those used in the Vectra GSi?
From what im told the 2.6 in the Vec GSi was "tuned" by MSD, to have slightly higher lift cams and supposedly creates around 190bhp, opposed to the book figure of 170 for the 2.5.
Im not sure if the Omegas use the same engines tho...

The engine is similar, but there are differences - certainly different intakes on Vectra-C. Omega tuning will be different, partly due to multiram setup (to flatten the torque curve), partly because its heavier. No special cams in any of the Omegas.

Cheers dude, thats helpful :y
Maybe im biased, but i think i would go for the 2.5v6, simply because its been around alot longer, so i assume there will be more info about it around the tinternet. Oh and the fact that you can use the 3.0l cams on the 2.5.
Altho you might be able to use the 2.6 MSD cams in the 2.6 Omega engine, however im not sure if you can, infact havent really heard anyone do it!
Best ask on MigWeb.

Lol, I love these sorts of posts.
The engines(-2.5-26 and 3.0-3.2) are no different (the only major change was on the 3.2 which got a steel crank), slightly more cc on each but, lower compression ratio which was a shame.
The management system did change but, not by much, drive by wire throttle and coil per plug setup (less reliable).
The lower compresson ratio allowed for the removal of the EGR setup and the extra pre-cat supported removal of the air injection.
Given the above, it means there is jack all in it.......and to drive, if both are in good order, you cant tell the difference!

Oh yes, no secondary air gubbins to go wrong... and the 2.6 will come in a much better looking body shape, with a far better interior. Esp if in elite which wont have those nasty leather pleats in the door cards, ar whole a far better car... For me... :-)

Ahh, facelift, you mean that inferior quality on internal finishes ;D
As to engines, nothing between them from performance side, 2.6 has some expensive reliability issues around the expensive coil packs, and the throttle body.

ok im going to view the 2.5 pre face lift that was in my first link .
Will view this tues and try and drop him down, yes its slightly over priced but it looks stunning, just need to look around the engine, anywhere specific i should be looking?
-
Supposed to be better rust proofing with the facelifts
-
will have a solid look around the body work, do these things rot underneth in any specific areas?
-

Mainly just the doors
-
Yes thats where i mainly see on pics, as its an autobox im guessing just looking out for the usual jumping in/out of gear and any Transmission noises, as i say i have worked on these many moons ago BUT the Forums and Enthusiasts always know best, any pointers guys to this?
http://search.autotrader.co.uk/es-uk/www/cars/images.action?R=200842321384220&channel=CARS&adcategory=&largeId=831551600
-
well, it does'nt have the usual elbow shaped bubble in the centre arm rest.
-
meaning not worn?
Did notice the light on the dash but one is i belice TC which comes on when engine is just started up i belive, and is the other sport mode?
-

Yes, not worn, or the driver does not lean on it much.
Laidy owner maybe. Or its been changed, does it match the miles?
The traction control light could be an issue. Press the tc button on the centre console. If the dash light does not go out could mean breaked abs ecu which runs speedo, abs, and tc. Can be recond. for about 100 afaik. Never had that issue tho. so maybe
Another member can better advise you. S light is sports mode, button on top of gear lever.
-
I think one is ABS, TC should go out very fast, you can see its up to a good temperature so it has not just started, the sport mode is further over to the right
-
So this coul dbe an issue, tho its not stated in the add, neither is the mot or tax.
Put an offer of 1500 on this and the guy says yes, what do you think?
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=160306524686&ssPageName=ADME:X:RTQ:GB:1123
Sorry to multi post as this link is also on my introduction Thread, feel free to move or delete which in inapropriate.
-
Looks nice enough
-
Yea the low milage and history looks impressive, also nice to see owners/traders keeping service dates upto scratch.
Seems a very nice car, will ring him at work tomo and ask him if i can look at it tuesday! :)

Offer 15 or 14 unseen first maybe.on the red one i think we are talking about. If he agrees then have a look at it. Then go digging for faults and check the abs off warning light goes out when you press the button on the test drive and that the speedo works.
The second silver one. Looks like a miniface lift.
Looks presented in a more honest state, ie the leaves around the skuttle area(first thing to check there is the scuttle drain is not blocked, by the tax disc corner is a flap for pollen filter access, open it and see if there is water/leaves/muck in deepest part or a high tide mark. If blocked the water can over flow into the cabin, soak the carpets and bugger the heater fan motor sometimes leaves a musty smell and misty windows from the damp) and missing battery jacket. Think you can just see the elbow bubble on the centre arm rest on this one. Would suggest more miles maybe.
Head unit is as my old mig which had built in phone and 6cd changer in the boot cupboard right side. Presume this would be the same,
Bit pricey maybe?
I would suggest looking through maintenance section for good idea what faults to look for.
Not sure i got all the page loaded on the red one. Will have another look. Ttfn
-
Well i offered 1500 quid on the mv6 and he says yes, im put off by the Red one as the warning lights on the dash dont look good.
TBH with the same sort of money the MV6 has less milage, is newer , and has more spec.
Im steering towards the MV6 tbh and it looks in superb condition as stated and service history.
I also like the colour which is quite rare "ish" it has all the kit i need aswell.
I supose its just a worry finding a new car as you dont know what will come with it if it does but im liking the MV6 alot.
Is anybody near Northampton area at all? this is where i will be viewing tuesday hopfully. :)
Oh and again, thanks for the input so far guys, really helpfull forum this, gunna check out now to watch family guy, then bed for work in th emorning, i will ring this guy tomo and keep you updated as to what he says, night fella's. :)
-
just out of curiosity...can somebody tell me or pm me the top speed speedometre reading for the 2.6 auto that they know it will do...parkers says 139 from memory but after taking me 2.0 on a "private road" i dont believe it and want to know ;)

to post on topic... it looks like a good example but for example- why change the grill to the prefacelift when it's obviously a mini facelift?
-
.....
but for example- why change the grill to the prefacelift when it's obviously a mini facelift?
"prefacelift" and "mini facelift use the same grille if it's not an Elite. Mini facelift Elites had a colour coded surround to its Irmscher grille. :-/

Remember that production car speedometers typically read at least 5% fast, and that makes a significant difference at the naughty end of the speedo scale. GPS is much more accurate!

-
Just recently checked - speedo showing 163kmph at 160kmph (100mph) by GPS on standard size tyres (225/55R16). Was expecting more
-
Oh, and more related to the topic - in Switzerland there are quite a few post-facelift models with 2.5 and 3.0. In fact these can be found with manual transmission but 2.6 and 3.2 are only autos here. Am on lookout for a nice post-facelift 3.0 manual estate.
I would take time to find best example possible and not be bothered too much if it is 2.5 or 2.6.

Indeed. you can have the best (or worst) of both worlds depending on your opinion. ;)
I'd say the differences between engines are too insignificant to worry about.Mileage and overall condition would be much further up my list.

Looks like i may yhave this buety if its a minter has he says, i spoke to him and the bodywork is in A1 condition minor a few stone chips on bumper.
I asked if there was any kind of oil/coolant leaks or if it uses, he says not at all.
He says it drives like brand new and there is no wheel wobble (just incase wheels are buckled)
No rust or corrosion anywhere.
No dints or usual shopping trolley marks.
So all in all if i like it after a good look around it ile be driving her home tuesday, thanks for all the help so far guys.
BTEW what does MV6 stand for?
-
Motorsport V6 :y
-
2.6 is fine, except for a bad batch of valve seals which leak
A bad batch of stem seals? I know the issue and I also have the smoking on starts, but have always thought it's more common than just a batch of seals? Any more info on this?
-
The early Y V6s were fitted with slightly cheaper valve seals which leaked so after a year or so the original design (as used on X V6s) was used
-
Thanks for clarifying this issue. Any idea which engine numbers these "bad" seals have been fitted to? I think I've got the bad ones... and I do not have the courage to take the cams off, nor the money to pay the garage for the job...
