'timing marks' on a Mazda b6 engine?

The timing marks on the crank pulley are 2 little nicks about half the size of a pinhead about 1cm apart. The 'clockwise' one is the ignition timing mark. The one to it's left is TDC. To correctly fit timing belt, crank pulley should be at TDC on the compression stroke & 'E' & 'I' on the cam sprockets should be at 12 o'clock. It's that easy. But the camshafts can move on their own because of the valve spring pressure on the cam lobes, so make sure the camshafts don't move while your trying to fit the belt.
