the hose is U-Shaped on the top of the manifold. It runs up and to the back. It had clamps on mine. The hose should be flexible, mine was hard as a rock so I got a new one before starting the job. The front part of the hose pulls up and off, the back towards the firewall, is where the PCV valve is fitted into a grommet and the hose. That is clamped into place. Just loosen up the clamps and PULL that right UP and out. Replace PVC and re-clamp on new HOSE. 15 mins, very easy to do !!
REMOVE PVC VALVE WITH VACUUM HOSE STILL ATTACHED CHECK FOR VACUUM AT PVC VALVE PLACING FINGER OVER IT.IF NO VACUUM FROM PVC VALVE BUT THE HOSE TO PVC VALVE HAS VACUUM REPLACE PVC VALVE.IF NO VACUUM GETTING THROUGH PVC HOSE AND VALVE.LOOK FOR DISCONNECTED BROKEN VACUUM HOSE OR OBSTRUCTION IN VACUUM HOSE BLOCKING OFF VACUUM.
The pvc valve will be located on the valve cover. Or better yet will be inserted into the valve cover. Follow the hoses coming from your air cleaner ( air filter) to the one that goes to your valve cover. Your pvc valve will be at the end of the hose. pvc valve can be tested by pulling it out of the valve cover while still attached to the hose. Start the engine. Place your finger over the pvc valve and pug it with your finger. If you feel vacume then it is working properly. If no vacume is present. Replace pvc valve
it is small and threads into the lower intake near the front valve cover. if your looking at the front valve cover from in front of the vehicle you should see a small hose that goes from the right side of the cover to the lower intake. the part the hose hooks to also screws into the intake. that is your pcv valve
