I suspect that if it has jumped 1 lug you will be fine as the valve will only be a fraction open when the piston is at the top of the block.... The problems arise when the belt snaps and this leaves some valves fully or near fully open and the piston can then made contact with the valve.
jumping 1 lug will completely stuff the timing mind so the car will run like a lame dog! This tends to happen when Alloy cam belt pulley(s) are used and alloy is softer than steel the lugs get worn at the edge so causing sipping. This is why if you have a Alloy cam pulley you need to check it as well as the belt or get it hard anodized.

cheers brendan ,thanks for the info
it never broke so im just hoping the damage is minimal

the focus has a floating bottom pulley, id check the crank pulley is torqued properly as its quite common for people not to do them up properly when changing the belt, and as you say it has tippex timing marks it would suggest the person who last had it off didn't know what they were doing or had the incorrect tools for the job

I'm not sure on the torque settings mate but you use your old bolts, lock the cams off with the bar and lock the bottom end off with the pin, release the cam pulleys and the crank pulley, with the pin in rotate the crank forward until it is stopped by the pin, you will be able to move the crank slightly with the pin in but its in the right position when fully forward, word of advise though dont fully tighten against the pin as it may bend and if the timing is that far out you may not be able to lock top and bottom off together without releasing one first, hope this makes sense

These engines are a pain, as they have no key ways and torquing everything up correctly is essential, otherwise the pulleys can spin, which sounds like what has happened in your case.

You should use a new bolt for the bottom pulley, in fact I believe you get a new one with most kits, reason being it's a stretch bolt!

Camshaft pulley bolt (not Ti-VCT engine)*: 60Nm.... 44lbf ft
Crankshaft pulley/vibration damper:*
Stage 1 40Nm..... 30lbf ft
Stage 2 Angle-tighten a further 90 degree
The Astrix key says *Use new Fasters

In all fairness I would not retighten the crank bolt without locking the flywheel first. It is critical that the correct torque figures are achieved - how are you going to do this? Do not use the cam / crank locking tools! Take the starter out to jamb the flywheel to do it once and do it right with peace of mind.
There is no way I would want to turn a key on a car for the bottom pulley to spin - the starter out will put 1/2 hour on the job.
My opinion HTH

Its only on these I am thorough due to the lack of key way on the crank. The 1.8 and 2.0 are a sinch in comparrison and not much to worry about.
