Product Overview
The 90913-02111 / 90913-02101 valve stem seal is precision-engineered for Toyota 1.8L 1ZZ-FE and 2ZZ-GE high-compression VVTi engine platforms. These DOHC 16-valve cylinder heads experience elevated operational temperatures and high-RPM oil mist. To meet these rigorous demands, IVOK manufactures this seal using a reinforced deep-draw metal casing chemically bonded to high-temperature FKM elastomer, ensuring solid press-fit retention on the valve guide.
Produced under strict ISO quality control, this aftermarket valve seal provides exact radial lip tension and micro-metered oil control along the valve stem. It effectively prevents oil blow-by into the intake and exhaust ports, protecting catalytic converters and spark plugs from carbon fouling over a long service life.
Key Features
- High-Temperature FKM Compound: Withstands continuous cylinder head heat up to 200°C without hardening, cracking, or thermal degradation.
- Reinforced Metal Outer Shell: Provides rigid press-fit seating on the valve guide to prevent seal loosening or walkout under high RPM.
- Precision Calibrated Spring Tension: Maintains consistent radial contact pressure for accurate oil metering and complete leak prevention.
- Exact OE Dimension Compliance: Fabricated strictly to 90913-02111 / 90913-02101 specifications for seamless direct fitment and zero modification.
