Hi guys - I am soon to change the timing belt on my 07 Impreza EJ204 with AVCS - apparently extra caution is needed - especially with the inlet cams ? is there a way to lock the camshaft pulleys in position ? any advice on the potential pitfalls would be greatly appreciated - Cheers Steve C

the left side intake cam (I think) will want to jump - but no damage happens if it does. There are devices and tricks to keep stuff aligned if you search.
triple check alignment and do a tooth count after rotating the crank thru a few revs. before starting.

Well - I managed to download the service manual - things I did not realize ---- the air conditioning belt is "stretch fit" - the valves can get tangled up if you turn the pulleys the wrong way - they say the cam pulleys and cover backing plate (LH) must be removed (along with the tensioner bracket) to remove the waterpump --- WTF ?? surely not !
