PCV (Valve) Left Hand,  for 90~95 ZR-1 LT5. One (1) valve is required per engine. 

This particular PCV Valve is virtually impossible to find.  Don't throw your old one away unless you know it's bad. We recommend cleaning with solvent and dry with compressed air.  The valve should rattle when shaken, meaning the valve moves freely. PCV valves are simple check valves that can be tested after cleaning by simply blowing into each end.  If air passes into the bottom and does not pass when blowing into the top, then the valve is operating properly.

NOTE: This is a NEW, OEM (AC Rochester or AC Delco) part. 

NOTE: GM parts manual has the RH & LH PCV valves location reversed.  This PN is for the LH (drivers) side, NOT the RH as indicated in the GM parts manual.

Exterior finish/color may vary from photo, due to different ACDelco manufacturing versions.
