The PCV, or positive crankcase ventilation, valve is a crucial component within your Saab. The valve removes gasses from inside the engine crankcase. This process relieves pressure within the engine, and helps your vehicle to run smoothly. The PCV valve can become clogged with sludge and dirt, and when this happens, the valve will fail to operate properly, causing pressure to build up. It's important to maintain the PCV valve as increased pressure within the crankcase can cause oil to get past seals and damage surrounding components. Changing the PCV valve is crucial to your Saab's maintenance and upkeep.

Instructions

  1. 1

    Allow the Saab to cool for a half hour. This will prevent hot components from burning you.

  2. 2

    Open the Saab's bonnet and locate the PCV valve. The valve is made of white rubber; it's located on the crankcase and has a small hose coming off the end of it. Consult the owner's manual, if necessary, to find it.

  3. 3

    Using needle-nose pliers, grip the valve and pull it out. Removing the valve may require some force if it is dirty and old. Disconnect the hose by pulling it off the valve.

  4. 4

    Install a new PCV valve by setting it in place on the Saab's crankcase and reattaching the hose. Push the PCV valve down into place. Close the bonnet of the Saab.
