It's a 1.8 petrol right?
Check obvious - stuck throttle butterfly flap in throttle body.
On the cam cover the two hoses the connect to the inlet manifold, they are connected correctly aren't they?
The holes in the alloy cover haven't been mod'd - on to the air cleaner side of the throttle body should be about 5mm, the other to the engine side of the throttle body is about 1mm - don't want that on any bigger.

IACV stuck open or an air leak in the intake manifold. Or as suggested, throttle butterfly is stuck open or being held there be a tight throttle cable.

A diesel idling at 5K revs
Yeah that just occured to me when I reread this thread this morning.
A diesel idling at 5K revs
Its a petrol.
Theres definitely no are leak. I just started her up again and sat at 3000rpm. turned it off and started her aain and went up to 5000rpm. Seems likely that its the IACV. Is there any way of servicing this?

Block the throttle body with your hand. This will eliminate the throttle body completely. If it still revs, there is a leak into the manifold.
It's worth checking everything is connected to the manifold correctly. Things like the a
servo.
Are you using the manifold that came with the engine? Or the original engine's manifold.
