Skyhawk L4-121 2.0L VIN K TBI (1987)
Refer to the attached illustration for the correct service part numbers. When installing a P.C.V. valve, lightly oil the "O" rings. Seat the P.C.V. valve into
the cover by hand. Inspect to see that the bottom "O" ring is not showing; then install the retainer cap.
Some after-market P.C.V. valves are available that will fit into the valve rocker covers but will allow too much airflow and cause high oil consumption.
If a P.C.V. valve replacement is required, always use Part Number 25097214, which is identified "AC Spark Plug, CV-90OC".
Parts are currently available from GMSPO.
