The usual excellent stab at diagnosis from Simon (the original 'block flatting' man, as he replaced his own - Bongo - head).

There have been a couple instances on here where recon heads have been fitted and subsequently had a valve drop as some of the clearances where not checked. Hope it's nothing too serious.
