DIY: How to Replace a PCV on a BMW 325Ci

1. Open the hood of the BMW 325Ci.
2. Grab the black, rubber hose that connects to the PCV valve and remove it with a firm pulling motion.
3. Place one prong of the needle-nose pliers inside the PCV valve opening and the other prong outside the opening. Squeeze the pliers together and pull the PCV valve out.
4. Push the replacement PCV valve into the now empty hole in the engine block. Connect the black, rubber hose to the nozzle of the PCV valve. Slide the hose on as far as possible. PCV valve replacement is now complete.
