How do you line up the twin cam timing marks the 88' pathfinder?

There should be punched marks on the cam sprockets which need to be lined up with factory punched marks on the rear timing belt cover, immediately behind and just above the sprocket. Line those 2 gears up and bring crank shaft damper to 0 degrees top dead center according to first mark on dampers, left side as you face the motor check to see if your distributor rotor is facing the number one terminal if not complete full rotation because motor is on exhaust stroke.
