6. Remove the locking rods from the pulleys and remove the toothed belt.
7. Unscrew the camshaft pulley mounting bolt, holding the pulley from turning with a special tool, and remove the pulley. Check for leaks (by the presence of leaks) front camshaft seal.

If the engine is installed in a car, you can fix the crankshaft from turning by engaging 4th gear and pressing the brake pedal. Check for leaks (by the presence of leaks) front crankshaft seal.
