The one I like is when it comes time to replace the cam seals. They tell you to use a special spanner wrench to hold the cams still. Don't use the cam alingment tool to hold the cams as this could add a little twist to the them.I took the cams off and slid the seals off over the lobes and carefully slid the new seals into place using the same method. Be sure to add a little oil to the lip of the seal before installing them. Then torque the cams caps back to spec. Be sure to apply the sealer to the caps by the cam gears as shown in the book. Works great!
