chris, whats the gold/brass coloured cylinder mounted horizontal behind the plenum?  Put stethescope on it and could hear quite a large ticking from it. Not sure if its the culprit but would like to rule it out.

Sounds like the fuel pressure regulator to me. That will sound clicky to a stethoscope because it's probably acoustically coupled to the fuel injectors by the fuel rail. Nothing to worry about, IMHO.

Also, exhaust manifold gaskets are better on the 2.6 and 3.2 and rarely cause a problem. No EGR system on these either.

Took car to my local Vauxhall garage today and got the workshop foreman to have a listen.  He was very helpful and give me reassurance my fault was not serious but more annoying.  He advised the ticking is not lifters and not an air leak.  Thinks it may be one of two things.  he rekons its either an exhaust manifold gasket leak although he couldnt source the sound to any of the two manifolds or what he described as a small solenoid on one of the air pipes going to the charcoal canister.  He advised he has replaced this solenoid before on v6 vectra's which were making a ticking noise off and on. 
Has anyone ever had this solenoid problem before and where exactly is it?

Does he mean the "purge valve" fixed to the engine breather can at the back of the driver-side cylinder head. - the one with the red connector  (2 wire)  :question

i can see the pipe coming out of the drivers wing but i thought it went straight to the plenum. Maybe i am mistaken.  Can this purge valve be seen from the drivers side?

Easy way to check, disconnect it from the back of the black breather cover on the top of the plenum (It's the larger of the two pipes in the centre of the four pipes that attach here) and see if the noise goes away. You may need to cover the outlet on the breather cover with your finger :y

I will check that tomorrow as my wife is out in it.  I know the foreman today was removing those pipes.  He did comment when he reconnected a certain pipe (not sure which one) that the noise was worse.  He said when the noise got worse over time it would be easier diagnosed.  I would like to get it sorted in advance if possible.  Is this purge valve easy got at or is it a stripping job?  If it is the purge valve will removing the pipe be enough to stop the ticking noise.  Surely the solenoid within will still run unless wiring plug is removed.  Please advise?

as said before the ticking noise seems to be coming from behind the plenum at the back of engine bay.  Think thats whats so confusing as the ticking seems to echo in the space behind engine. Think thats why the foreman could not pinpoint the affending problem.  Is quite noticeable inside car at idle with windows up

this noise is coming and going and doesnt seem to have any pattern. sometimes its worse on start up and other times its better on start up and then comes when warm.  Foreman did state mine could be a manifold crack or gasket too.

Do this tomorrow to establish whether it is the purge valve, if so then it`s just a simple replacement
