Severe Ticking

Hi, long time since I used this site, but Megane Problems have hit once again.
I have a 2004 1.5dci with 80k on the clock, two days ago, as I came off the motorway I could hear quite a loud ticking noise. As I was driving I tried a couple things to suss out where it was coming from, finding that it was rev related, in or out of gear as I increased revs, the speed and volume of the ticking increased. I pulled in as soon as possible and popped the bonnet with engine still running, just after I opened it, there was a loud squeal, not like a belt slipping, the only way to describe it would be like a belt gripping and forcing something to turn. This was swiftly followed by the engine giving a good shudder, like it was about to die, before I ran to the door and switched it off.
A mate towed me home, where we looked at the car and started it again. Eventually coming to the conclusion that cylinders 2,3,4 are ticking ferociously while cylinder 1 runs silently.
Finally, the car had its cambelt changed by Renault about 12k miles ago, and had a service and oil change by myself 2k miles ago. Im pretty technically minded, and confident enough to give anything a shot, but cant afford to fork out to replace parts that are ok, what with a new baby on the way and a holiday booked for 3 weeks.
Anybody have a decent clue about what the problem could be, it seems to me that the cambelt may have slipped or shredded and the timing may be slightly out, but the car drives fine with no really noticible loss of power.
