Cheers for the imput guys, I've been sat in the bath pondering and come to the conclusion that;
A) the crankshaft cannot be 360 out as thats one full turn putting everything back where it was in the first place, if it was 180 out then it would be trying to fire on the induction stroke so wouldn't run at all.
B) the lefthand balance belt must surely be aligned as it makes the same amount of rotations as the crank and those timing marks I'm positive lined up correctly and was tensioned to give the 5-7mm deflection stated in the manual.
Therefore it must be the right hand balance shaft a tooth or half a tooth out. I was struggling over the pit trying to hold the exhaust cam in position while holding the belt on at the same time as trying to feed the belt round the idler, oil pump sprocket and crankshaft so it surely must be my problem.
Better get my screwdriver out tomorrow
Worth noting that the right hand shaft doesn't run directly of the pully wheel. Its geared off a sprocket which you can't see without having the engine apart.
The term 360 out I'd say refers to the pully it runs off as.
Easiest way to find out is to time everything up then as Nath said, remove the short bolt that's in the block behind the turbo. Insert a screw driver. Should go in a couple inches, if it doesn't then the shaft itself is 180 out and you'll need to rotate its pully 360 degrees to correct it
I should have said that instead of confusing the issue
