Mine is very rusty and looks a bit broken, it moves up and down a lot and the top appears to have sheared from the bottom, or maybe this is how they work. does anyone have a picture or close up diagram (the EPC is a bit small). 460 230GE

Best to just remove it and blank off the hole in the manifold and either seal the pipe that goes to the metering head or remove it and blank off there too. I would expect that the pipe inlet to the metering head will be clogged up anyway and the EGR will not be functional anyway.

So no use having one? or at least a faulty one no worse than none at all?

That's right, if it's not leaking I wouldn't worry and if it gets picked up as broken on the MOT just take it off. It was just a way of reducing emissions at tickover.

NB. if you do disconnect don't forget to seal the vacuum pipe.

Re: Exhaust Gas Recirculation Valve

Thanks for the advice, I'm trying to trace a ticking under load, if this unit is broken I guess it could be causing a manifold leak which would give a ticking noise.

I'd like to decide if it's broken without dismantling as the whole assembly is so rusty I can see it being difficult to shift the bolts.

Are they supposed to have a couple of inches vertical travel?

Went ahead and blocked it off, seems to have improved running slightly. It was completely broken.
