Detailed Description

The DJ Rock EV136 exhaust valve is manufactured for engines that require a heat-resistant valve with stable dimensional accuracy and reliable sealing performance. Its nitride-coated finish helps reduce friction and supports durability under high exhaust temperatures, while the application-specific design helps ensure proper compatibility with the listed Hyundai Sonata, Tucson, Santa Fe, Tiburon, and Kia Optima and Sportage engine configurations. If you are replacing a worn exhaust valve during cylinder head service, valve job work, or engine rebuilds, this part number EV136 provides the critical dimensions needed for a direct-fit repair.

This exhaust valve is used in engine valvetrain service where burnt gases must exit the combustion chamber cleanly and consistently. The precision-engineered construction supports long-term structural stability in severe thermal environments common to modern gasoline engines.

Common Problems This Part Helps Address

• Burnt or pitted exhaust valve faces
• Loss of compression from poor valve sealing
• Exhaust leakage at the cylinder head
• Valve wear from high-temperature operation
• Engine performance issues tied to damaged valvetrain components

Installation Notes and Tips

Verify valve head diameter, stem diameter, overall length, and lock groove count before installation. This EV136 exhaust valve is intended for cylinder head service and should be installed with proper valve seat inspection, guide measurement, and valve lash or clearance checks as required by the engine specification. For best results, confirm the exact engine application against the vehicle’s build data, including the 1999-2001 Hyundai Sonata VIN V note where listed.

Quality Assurance

DJ Rock lists this exhaust valve as a premium replacement part manufactured to meet or exceed OEM quality standards. The nitride-coated construction and heat-resistant material selection are designed for the thermal demands of exhaust-side valvetrain service.
