Hi all,
My first post here, so hello!
I'm going to look at a 2002 Omega 2.2 this weekend. I used to have a Vectra and I'm not actually looking for an Omega, they appear to be pretty good value for money. Anyway, when I had the Vec, I heard of the Cam Chain snapping on the 2.2 because of a problem with oil not lubricating the chain. Anyone know any more info about this and if this is something I can look out for?
Also, anyone want to give me some tips so I don't buy a complete dog?
Cheers!
Dave

No chain on 2.2 but belt and tensioners. find out when it was last changed from owner.

if the motor code starts with a z it will be chain (after 2001 i think) if it starts with a y it will be a belt, usually will have a sticker on the slam panel if it's belt for service intervals e.t.c. as to regards with the timing chain snapping i believe that was not on this motor but the se motor which didn't come out in the omega where as this would be a ev motor? as for checking for dogs i'm relatively new to omega's but if i was looking at one i would be checking steering straight braking e.t.c and ofcourse service history, most omega's have history as they are a fairly conservative exec car so if this is lost i would look deeper into it

All 2.2 petrol Omega's have a cambelt. The 2.2 DTI is a chain.
The cambelt along with waterpump should be changed every 40k miles or 4 years.

I stand corrected! :-[ so it's a mine field out there am i correct in thinking that the z motor is an alloy block as opposed to the y motor which is a cast block :question if not where lies the difference!
-
The difference was in EURO norms y22 is Euro3 and Z22 is Euro4. Think only small difference was in ECU programming
-
All Omega Petrols are belts.
2.2 and UK 2.5 diesels are chains.
All Omega belts are 40k, ignore any printed or verbal advice suggesting otherwise. For 2.0/2.2 do waterpump at same time.

Great thanks for the replies. I thought the 2.2 petrol was a chain!
Always found looking for cars such a ball ache. When I was looking for a Vectra a few years ago, all I heard was "Oh yeah it had a belt at 80k". Wrong interval and it didn't have the rollers/tensioners changed >:(
Cheers!

Indeed, the Omega 2.2 petrol and the Vectra (and I think it went in some Astras/Zaffys) 2.2 are very different engines
