Sounds like its dropped a valve tbh mate.
Give it a compression test and stick your readings up.

Definately not a good sound no  Who done the cam belt ? possible the tensioner wasn't done up correct ? I'd start by the compression test first although the way it sounds somethings definately touching and may cause more damage the more its ran then you will be looking at other things to replace  I'd start by checking the tension of the belt and check the timing marks atleast then you can see if anythings moved! Then take the rocker cover off and see if anything is visible from the top i.e snapped cam chain ? abf inlet cam is ran from the exhaust chain  i'm guessing its a head off job though  let us know how you get on sorry to hear about it i know your pain luckily its not your daily

1stly id take the plugs out and have a look,   

if ones tight and wnt budge or come out and the ends smashed off it droped a valve

to be sure you can lift the cam cover and see if a tappet isn't fully returning.

or its possible you luffed a downchange and buzzed the engine and it caught a valve
