I know this is silly as i should have checked but which way does it rotate im thinking clockwise as i need to line up the markings.

Big 90k service for me, actually it's relatively easy once you get going.

Oddly ive tried undoing the crank bolt and the engine jus keeps spiining freely despite being in gear.

Edit: sorted the rotation but am i right in thinking the rh cam pulleys move once you remove the belt?

 

rh inlet will move yes

 

Thanks, i used mole grips to hold them nicely in place, so long as the lh cams are lined up is there no touching them if i rotate the crank?

As you say the rh inlet would naturally.

 

if you get it in the right place they don't move!

 

The lh cams didn't but the crank did when i undone the belt, but id imagine it should be fine, i didn't hear anything at the time.

I'll have to get me a new crank sprocket now as one of the lugs decided to go, oh and a new coil pack as one is up the duff.

The crank sits happily on the alignment mark, least it does now ive lined it up.

 

So does anyone know, if i rotate the crank while the cams are in their correct position will any contact occur?

 

yes if you rotate through 360deg but just to align by a few degrees then no

belt alignment is here
