hi there i am trying to change a cam/timing belt on a 1999 citroen xsara 1.6 8v ok and i have taken the belt off :blink: but my question is this how do i set the timing up and how do i know the cranksthaft and camshaft are in the correct position ? im sure i did not move anything but it might be a tooth or 2 out and i dont want to bend valves and stuff . thanks any info would be great.
