I viewed Steve Saunders timing belt change video on this website. When I took off the old right side belt my cam pulley slipped out of place like his did in the video. I installed new belt on left side with no problem and all marks lined up. When I went to the right side and put new belt on, pulley was still not lined up. In the video it doesn't show how he realigned the pulley that slipped. How should I fix my problem?
