Detailed Description

The Standard Ignition V243 is engineered as a direct-fit PCV valve for vehicles that use a push-on, straight-nipple design.

Standard Ignition applies manufacturing quality control from component sourcing through final assembly to support consistent replacement performance.

This part cross-references Dorman - HELP 47033 for the same application. It is also listed under Standard Ignition PC68.

What It Helps Address

• Rough idle related to a restricted PCV valve
• Excess crankcase pressure from a worn ventilation valve
• Oil vapor buildup in the crankcase ventilation system
• Emission system faults tied to PCV flow issues

Installation Notes and Tips

Verify hose size and nipple orientation before installation. This valve uses a push-on attachment method and no connector, so it should be matched to the original hose routing on the vehicle. Confirm fitment by year, make, and model before ordering, especially on Chevrolet Malibu, Pontiac Grand Prix, and Buick LeSabre applications.
