Pulled the cam cover off. I was trying to get the roll pin out without removing the cam plate. To avoid touching pushrods. I cant seem to figure out how to get the roll pin out. Do you tap it thru from the front and pull it out the back of the cam plate? Or tap it from the back and pull it out the front. Also even after I get the roll pin out the pin that holds the Primary Chain tensioner in place looks like it would be in the way of pulling out the Spring and the hollow piece that holds the spring in place. The primary chain tensioner pin goes across the hole where the pin sits so how can I get the spring out if this is hole and in the way? Do I need to remove the primary chain tensioner to pull the spring out of the hole? Manual says to remove the tensioner. I have heard you can do this without removing anything but cam cover and front exhaust. Anyone done it this way?
