Here is how I replaced the oem PCV valve and grommet in a Hyundai trajet 2000.
Step 1: Removing the Oem Valve and Grommet.
I removed the spring hose clamps on other end of the vacuum line to the valve. Next I pulled it out with a piece of its grommet. I had to Pry out the other piece.
Step 2: Installing the New Grommet.
This was extremely easy. Just pop in!
Step 3: Installing the New Valve.
Using both hands and strength I popped the valve into its grommet.
Step 4: Completion!
With new silicone vacuum hose, the pcv valve is back in service!
