Technical punto 1.2 16v timing with tools

just for fun i checked timing again and when it lines up i cant insert tool to lock the cam smoothly, i can put it in but at a slight angle- cant crew it in tho, does this mean timing is out? tried with loose cam pulley when tightening belt tensioner but its still same, it feels like it gets out of timing when im turning crank
 
yea lucky fuse blew

An old belt will have stretched a little.

Loosen the cam pulley bolts, then move the cams to insert the locking pins. Might need to slacken tensioner, or remove belt. With cams in correct place, then tension belt and tighten bolts. This puts the cams in the right place in relation to the crank, with the new belt.

The slight difference you have now is unlikely to do any physical damage, but may well lose some power.
 
It will stretch a little immediately it is used. Although almost impossible to measure. Belts should be identical, but production tolerances may give small differences. The movable pulleys will set the cams in relation to the crank, and allow the belt to keep them there, rather than determine the cam position by the belt. Just more accurate, as you have found, just by a small amount.

Something does not seem right to me. If you do not undo the cam pulley bolt you need to do the timing in a very particular way to get the belt correctly tensioned on the water pump side.

The only way to get the belt on without undoing the cam pulley bolt is by fitting the belt with an extra notch of the notched belt on the water pump side to give you sufficient slack to get the belt on. You do that correctly by rotating the crank pulley anticlockwise just sufficient to fit the belt after you have timed the engine, fitting the belt, and then rotating the crankshaft till the belt turns the camshaft which tightens the belt on the water pump side. When you then tighten the tensioner the two sides have sufficiently equal tension.
