Inspect the rubber grommet in the valve cover and the rubber coupling for brittleness or cracking. Replace parts as necessary.
Insert the new PCV filter through the hole in the air cleaner with the open portion of the filter upward. Make sure that the square portion of filter behind the nipple fits into the (square) hole in the air cleaner.
Install a new spring clamp onto the nipple. Make sure the clamp goes under the ridge on the filter nipple all the way around. Then, reconnect the rubber coupling and install the air cleaner cover.
