    Not really. It's louder, or at least more isolated from inside the cabin. I did try listening to it via a long screw driver touched on various bits, and if anything it was loudest on the top of the cover that goes over the spark plugs. Like a tappit type sound. But it's more 'whirry' when I drive. And I didn't stick the screw driver down inbetween the belts / pullys

    Sorry. I know noises are hard to diagnose if you can't hear them! The video posted earlier is pretty much the sound. Thanks for bearing with me.

    Ahh. Bit of a mistake on my part then. I'll try and record it tomorrow and get a youngster to upload it somewhere, and post it up

    Ok, I attempted to get a video of the sound. It seems to be coming from the drivers side of the engine bay, probably towards the front. Any clues?

    tighten your exhaust manifold.

    Don't over do the nuts otherwise you will snap a stud off.

    no problem.

    Also your injectors are a bit on the noisey side but that is nothing to worry about.

    Righteo. Eventually got to the manifold and tightened the bolts. Only two moved and only by a mill or so, and the noise remains. I pulled of the auxiliary belt and started it and the noise is still there, so I think I've ruled out pulleys etc on the crank shaft, a/c etc. I pulled the top cover off the timing belt and the noise seems to be coming from the two camshaft cogs at the top. The front one in particular spins pretty wobbly but seems on tight. But it could just be referred noise from lower down in the timing belt area. I haven't pulled the bottom cover of that yet. I guess thats next, but its probably beyond me to do a timing belt. The belt is in good nick. Not sure where to from here
