Detailed Description

The IV314 intake valve is engineered for engines that require accurate valve timing and stable sealing under heat and mechanical stress. Its nitride-coated finish supports long-term wear resistance, while the 3-groove stem design and specified dimensions help ensure proper fit during cylinder head service. This part number IV314 is a practical choice when replacing a worn or damaged intake valve in Chevrolet Malibu, Chevrolet Cobalt, Pontiac G6, Saturn Vue, and related GM models. For technicians working on Chevrolet Malibu or Saturn Vue engine repairs, the IV314 provides the dimensional consistency needed for rebuild accuracy.

What It Is Used For

• Restoring intake valve sealing after wear or heat damage
• Correcting rough idle caused by poor valve sealing
• Addressing compression loss related to valve wear
• Replacing a bent, burned, or corroded intake valve
• Supporting cylinder head rebuilds and top-end engine service

Installation Notes and Tips

Verify valve head diameter, stem diameter, overall length, and groove count before installation. Match the valve to the cylinder head and engine specification listed in the fitment data for Chevrolet Malibu, Pontiac G6, and other supported applications. Professional cylinder head service practices should be followed during inspection, cleaning, and final assembly.
