Ive done senators and ive had 3.0 auto omegas but im looking for a change and ive found a 2.6 manual omega cd on 2001 plate.
What are the engines like for power and reliability?,
i cant seem to find any details anywhere but in my opinion the 2.5 engines were terrible , i work at a breakers and get asked for these engines and heads all the time , im wondering is the 2.6 gonna be the same thing.
thanks in advance

Change back to a Senator .... you know it makes sense Rodney! ;) They don't rust like an Omega and there's not as much electrickery cr4p to go wrong either! :-X

2.6 manual should be a good mix of power and economy. The manual box will give you a bit more economy in town compared to the auto. I find the manual box a bit clunky (did improve after an oil change) but this is minor really (still better than most FWDs)
If you are interested in a manual then it is a 2.6 unless you want an ex-plod 3.2
Not sure why you have the impression that the 2.5 is unreliable, they should be as robust at the 3.0. Often an oil cooler failure is mis diagnosed as a head gasket failure: that could be why lots of people are after relacement engines.
Good luck

The 2.5 is a VERY reliable lump, as is the 3.0. The 2.0, whilst underpowered, is also a very strong engine. The key to keeping them all alive is 3k oil changes...

i really dont get asked for the other 2 just the 2.5 strange! , oil change every 3k seems a lot , would i need to do this on the 2.6?
thanks for your help guys i appreciate it.

3k is a tad extreme, but its what i have been doing. It depends on the millage you do, if its heavy town stuff like me, then 3k, is enough. But longer motormiles and it can be longer.
5k oil changes are the norm i'd say, at the end of the day it costs me less than £10 to do an oil change, with geniune GM filter and oil! So a change every 3k is nothing!

main reason is people dont change cam belts every 40000 miles or 4 years and when it goes knackers the heads !! bloody good motors bud all of them if well looked after !! ;)

Totally agree, and by the way Omega everytime, depends on how much you cherish and look after the car depends on how much rust appears, if any.

;D ;D ;D ;D look after the miggy and she wont rust.

right its bought , gonna change oil every 5k i think will be about right for me.
thanks you lot :y

Mate 3 k oil changes is a tad steep i'd say every 5k as long as you use a good oil..
Don't know where you heard about the 2.5 being crap, i've had three 2.5's and two 3.0's and all of them have been fine..
Like some one else pointed out, a faulty oil cooler goes and every one thinks it's head gasket gone so alot end up scrapped for no good reason..
Ive had my 3.0 elite now for 2 weeks and it is a absolute corker of a car and you can pick them up for peanuts mines a auto which is a little thirsty round town and short trips so a manual would be alot better for fuel eco... :y

Not sure I agree - With the 4 for 3 offer on genuine VX oil, an oil change is going to cost around a tenner.
If you do say 1000 miles a month, and do 3k oil changes, that's £10 every three months.
That's only £40 per year, for the single most important peice of maintenance you can ever give your engine :y

...and as Richard is an ABS member then one might assume he has a trade card! :y

GM V6 lump is bullet proof and very reliable. The reason they go left right and centre is because owners skip the mandatory timing belt change at 40k/4y, but this is not a weakness of the engine it is a straightforward maintenance issue which incidentally affects the vast majority of modern belt-driven engines. I suspect the reason you did not see that such a demand for 4-pot engines is that on a 4-potter removing the head and fixing the problem is not that expensive so the engines get repaired, but with the V6 it is just too much work so a second-hand engine (or heads - with all of the 24 valves already in) makes more sense.
The 2.6 is easier for DIY than the 2.5 as it has less auxiliaries i.e. no EGR, ICV, HT leads, etc (it is all ECU-controlled on 2.6), but it is otherwise very similar to the 2.5.
Very powerful and smooth engine with very reasonable MPG for its size.
Go for it and get the cambelt and tensioners changed asap, and you will be fine....

I will also confirm that the 2.5 is a reliable lump, as are all the petrol Omegas. If you are getting a lot of requests for heads, that will be due to snapped or incorrectly fitted cambelts. The interval is 40k/4yr, no exceptions, whatever dealer/seller/mechanic may say. Also, it is about the only engine on the market that cannot have its belt changed without a locking/timing kit, despite what mechanics may say.
The same goes for the 'warped cam cover' myth put about by incompitent mechanics. If you do have to replace cam covers, use genuine gaskets. And clean the breather system.

Senators not rust? Electrics more reliable than that on Omega? LOL, can I have a puff on what you've been smoking :o

I didn't say Senators didn't rust at all - rear arches. But ....... I'm not even going to have a nibble ..... :-X :y

You will need nibblers to remove the rust from a senny ;D ;D ;D ;D ;D ;D
