[aggie]

Undo the M6 nut and move the wiring harness from your line of view and shine a good torch in there,the gearbox for the 102bhp isnt kind when finding the timing mark,the mark comes round so tight beneath the pointer its hard to see. The mark is usually a V with a 0 behind it.I use a fibre optic camera to find the mark but only with this gearbox,they are a pain in the anuss
Try your camera phone down there on zoom to see if it helps. If you have the cam cover of then no.1 cyl cam lobes will be up as the marks coming round
