That will be a leaking diaphragm valve then. Time to overhaul the valve block. you can get the bits from symlise on ebay (no connection)

If there is air leaking from the exhaust it is the usual culprit. Easy enough job, just need to be clean and careful. If there are any white powder deposits in the valve block, replace the air dryer as that is a sign of the dessicant breaking up.

If there are bits floating around in the valve block they are probably from the dryer, good idea to replace it when you do the block
