I need a photo loction of a PCV valve for my 1998 Buick Lesabre Custom
Would like to replace it myself.
Standing in front of the vehicle the PCV valve is located on the left side under the MAP sensor. You'll see the MAP sensor is a small square box looking thing with a 3 wire plug on it. You must remove the MAP sensor by spreading the plastic retaining clips (which will probably break). Then using a socket of the correct size press down and turn the clip assembly counterclockwise to remove it. The PCV valve will be right there. See the attached picture of the PCV valve kit to buy before you attempt this! Hope that helps! Jim
