Remove / Install Positive Crankcase Ventilation (PCV) Valve (’91-’95 DOHC Aluminum Valve Cover)

Author: Jonathan Swain (aka "PurdueGuy")


This guide is for the DOHC engine with aluminum valve cover, found on most (but not all) 1991-1995 SC/SC2/SL2/SW2 models. However, it’s very similar on other models, and even on the SOHC engine.

PCV = positive crankcase ventilation.  This valve lets air escape from the valvetrain area and into the intake.  A clogged/bad PCV contributes to valve cover leakage, so replace it if it does not rattle when you remove & shake it.

Step 1

Grab the elbow connection to the PCV, and pull outward from the valve cover. It can be a little tight, but should generally be able to be pulled out by hand.

Step 2

Twist & pull to remove from the elbow connector.


Installation is the reverse of removal.
