General punto servo problems help!!

[urchin]

hi all i have just brought a punto and i love it! its a 2001 1.2 16v hlx its so comfy after the panda today i gave it a service and changed the cam belt which im sure you know means removing the inlet manifold to fit the locking pin in the back cam. all went well it timed up fine i built it back up turned the key and it started reving up and down and i can hear an air leak around the brake servo area if i remove the servo pipe from the servo and block it it runs perfect all pointing to a leaking servo, it just seems a hell of a coincidance thatthe sero should fail while im doing the cambelt. any ideas

dunno about the servo, but you only need to fit the front locking tool to do the belt, as the cams are joined so if front locked back wont move
