I took the valve cover off, etc....I marked one of the rollers with a mark on the edge then marked the chain with a mark on the arrow printed into the cam phaser to line everything up. When I removed the phaser I kept tension on the chain and started to put the new one on but I think the chain moved a little so the mark on the new phaser and the one on the link in the chain are now not matched up.
My question, on the back of the phaser is a pin that seats into a keyway on the shaft and this means the phaser will only go on one way. If I rotate the phaser one chain link at a time until it seats with the other marks on the cam lobe lining up I should be ok? It doesn't matter what the mark on the chain is because the chain can go on any way much like a bicycle chain on a sprocket as long as the phaser lines up correctly and slides on ? I hope?
