Timing Belt (Cambelt) Alignment Procedure
Hello I'm looking for a bit of help please. It's the first time I have done my timing belt on my 1994 Subaru Impreza wrx import. The reason I am doing the belt is my water pump failed. So when I went to remove the belt I made sure that all marks joined up as they should and just to make sure that they were matched properly I remarked them in different spots. Took the belt off and replaced water pump. Now it's the next day and I proceed to replace the belt but the two right side cams are of now if I try and line them up its like there spring loaded and just jump back making it impossible for me to line them back up so now I'm stuck. Sometimes just doesn't seem right ��
Would just like to say thanks to mick for the step by step took me 2 days because of the lobed cams she fired straight up and sounding nice cheers

Right side cams - passenger side I take it, if so its normal for the cams to be 'on lobe' and makes it awkward without locking tools.
This is how I do it (AVCS shown but they are all the same) :
Set your crankshaft line to the oil pump mark and put your cam belt on.
Working anticlockwise,set your Right hand (turbo side) cam pulley marks to the inner cover marks and slip the cambelt onto the inlet pulley first and then the exhaust.
Feed the belt onto the lower idler and water pump idler and around the water pump pulley.
Set the Left hand cam pulleys as shown
Inlet cam is on lobe, exhaust about to press down on the buckets under the cam lobes and feed the belt onto the exhaust pulley first and clip the belt to the pulley.
Feed the belt onto the inlet pulley (without moving the pulley as it is on lobe) and clip it to the pulley.
Rotate both pulleys together anticlockwise making sure there is no slack on the belt between the pulleys, until the pulley marks line up with inner cover marks.
All the slack on the belt is now where the tensioner sits - fit the tensioner and torque up the bolt, double check all timing marks are lined up and then pull the tensioner pin to tension belt.
Hope this helps

That is spot on mate cheers for that I will let you know how it goes �� I was just getting a bit worried because every time I turned the right side cams (passenger side) it turned half a turn the sprung forward. ��
