FORGETTING to check your PCV valve is really easy to do. The job of the PCV valve is to regulate unburned fuel mixture back into your engine so there is less pollution. If the PCV valve malfunctions, you can throw too much unburned fuel and oil right onto your intake manifold valves. When you see the valves in this video because the PCV valve went bad you want to run out to your car and check it. Taking off the intake manifold is not as easy as it used to be. Scraping off large amounts of carbon oil discharge is also not a fun job. Not only did we need to use a pic to scrape off these deposits but we used walnut shells in a sandblaster to safely remove these deposits from the intake valves. The diaphragm in the PCV valve was completely disintegrated and was allowing too much pressure from the crank case. Typically these PCV valve‘s are pretty inexpensive so periodically checking to make sure everything is operating correctly is a good idea. Hope you find a video useful.
