Omega 2.2 engine

Omega 2.2 engine. Not what I thought one would look like. This one is W reg 2000 model. I was thinking they had the same engine as the z22se dunno..

vocky

it's the x22xe, same as a frontera (except the frontera has a lower compression)

Daz

Same as the X20XEV to look at,but with diff stroke/pistons i think..

Did the Omega come with a z22se fitted?

Daz

Nope...

I always thought the newer ones had them. I was thinking about getting one some day if it has the z22se fitted

the omega never had the z22se, but the x22xe was replaced with a z22xe (electronic throttle) 🙂

I was also confused about this engine in Omega. I always thought that this is only a mistake.
Could you please explain the difference between z22se and x22xe?

the easiest differences to spot;

x22xe has cast iron block

inlet and exhaust are opposite sides to z22se

no parts are interchangeable :roll:

And Z22SE is fitted with a cam chain. But what about power, reliability , faults?
I am thinking of buying a Omega, but I think that chain (if serviced properly) is better than belt. I know that there were no Z22SE in Omegas, but I am also thinking about Vectra.

just being curious Neil, but any idea why the inlet and exhaust is opposite way round on the z22se??

the 2.2 omega is rear wheel drive, usually an auto, the valve stem seals tend to fail, water pumps fail, cam belts can snap

the 2.2 vectra is front wheel drive, manual and auto versions, early cam chains can fail, low oil level can cause big ends to fail

both cars otherwise quite nice, the later omegas are a good spec - I would advise to go for a cdx, the last of the vec B's are also a good spec - I would advise to go for a sri or cdx
