I am in the process of changing the timing chain on a 2007 Almera . The timing chain has been removed but I'm unsure as to how to reset/lock the vvt pulley on the intake camshaft. The pulley has some 'free' travel at the moment . If I turn the pulley clockwise (looking in from the wing) while holding the camshaft and applying air pressure to the port in the head the cam seems to lock . Is this where I should have it for refitting the chain ? A friend in the trade sent me some info - but this mentioned 'locking ' before removing the chain ; but I had the chain removed when I got this info. And despite much searching I have been unable to find out what to do in this situation . It mentioned hearing a click - but I can't hear any click. Any help/advice greatly appreciated .
