Which engine should I go for.

Sir Gingerlot · 05 March 2007, 16:20:04

Thank you for all your comments. It looks like most of you who replied prefer the V6's. My last remaining doubt is whether they are reliable. Most of the posts on this site seem to be about the V6's in various states of repair. I presume this is because there are so many of them out there and not that they tend to break easily. My cousin works for Vauxhall and has warned me that the V6's are a pig to fix and very expensive in labour time. If you disagree please let me know. I have seen some great 2.5 V6's on the internet so just need a little more convincing.

Thanks

They are pretty easy to work on for most things. They do need cambelts every 3 years or so depending on how much you drive. Mainly, they are cheap and usually need a few things doing when they are sold, like cam cover gaskets. Look very carefully at the records of recent service. Mine already had the HBV and oil cooler done when I bought it.

the 2.2's i think tend to be more reliable, they can be abused and still go (although not very well)

Very few posts in the help section refer to the 2.2 / 2.0 engines. (apart from mpg

)

Went to Slough today, me and a m8, full boot. Did not feel underpowered, joining motorway on an up hill ramp, 40 to 80... pulled well.

The 2.2 is fine until you get to 80... it will sit there all day long no problems and return 35+ to the gallon..... however try and go past 80, and it takes a while to wind up the speed.

Also 4 passengers in the car really hurts the 2.2 were as the V6's are fine, because its just me in it 90% of the time and i am skinny git (10 stone) it goes fast enough for me

Not sure I could agree with that. Most of the car is identical, and mechnically, the v6 engine is strong. Failed cambelts kill both engines.

The V6 in a FWD car is a tight fit. In the Omega, there are a couple of common components that are a bit tight - HBV and DIS. Not impossible though. I have to say, you're cousins' comments are not uncommon from Vauxhall technicians, they are just scared of Omegas, which may be why so many are so poorly serviced.

It might be big but there is nothing to be scared of, if anything it is probably easier to service than a FWD car with everything jammed into a tiny space

To me there seams to be less issues with cooling, rocket cover gaskets, oil leaks, with the 4pots compared to the V6. Weak point on all is the belt.

Most of the engine related posts in general help are related to the V6

From my experience, the 4 pot does not last as well as the V6...........

The HBV is the same on both

They both have simialr lead/DIS/coil pack issues.

They both suffer cam cover leaks the same.

The 4 pot is more prone to blocked breatehrs (probably due to the way it wears faster)

They both have the same service intervals....

2.2, also has an oil cooler (keep to the service schuduel and the V6 one is not a problem)

A V6 Omega certainly isn't a cheap car to own. I've already spent shed loads on it in the last 5 months since I bought it.

Chopsdad · 06 March 2007, 21:34:47

How about this one?

The V6 is a good reliable unit if it is maintained properly.

Most of the issues are down to lack of previous maintenance/incompetence(see many Vx "technicians").

Buy the right car (eg Marks if he ever decides to sell!

) and follow the correct service schedule and you should have a good reliable car.

As for difficult to work on? Not at all. There are some things that are awkward but you won't find a better support network for an owner than this place.

Not sure I agree with this comment. I had a 4 pot on a veccy and I spend less time under the bonnet with the meega than the veccy. in 2 years on the veccy I had : valve stem oil seal blow (complete head refurb done at the same time) new oil level sensors in the sump, timing belt change required at the same interval to be sure, although it is easier to do, breather curcuit blocked, rocker cover gaskets, rear bushes......... sound familiar?

Happier now I have the meega 8-)
