I took the car to Halfords at lunchtime (needed a spark plug socket) and took off the non return valve. Started the engine with it disconnected and - hey presto - dashboard rattle had vanished. Reconnected and the rattle returned, but slightly less loud (I blew in the valve to clear any debris).
I found this thread on here - JPB recommends dropping the valve in a mixture of hot water and soap powder overnight, letting it dry and refitting. I'll try that first and, if it fails, source a new valve.
(Checked the spark plugs while I was there. They're fine, so must have got the mixture right - though I got my first blood on the engine block from scraping my finger while loosening).
Thanks again for the help.
Cheers,
Ben
