A-Premium Valve Cover Gasket Set for Toyota 4Runner/Tacoma 2.7L 1996-2004 - NBR/ACM Oil-Resistant OEM Fit

A-Premium Engine Valve Cover Gasket Set replaces worn seals to stop oil leaks and restore a tight, OEM-fit seal for compatible Toyota engines.

This complete gasket kit contains the valve cover gasket, oil seals, and washers engineered from Nitrile Butadiene Rubber (NBR) and ACM compounds to resist engine oils and temperature swings. It’s designed for direct-fit replacement on specific Toyota 4Runner, T100, and Tacoma engines, matching original dimensions so installation is straightforward and reliable.

How does this gasket kit stop oil seepage around the valve cover?

The kit supplies a full set of seals that replace aged, hardened, or damaged rubber components that commonly allow oil to escape the valve cover area. The materials are chosen for oil resistance and dimensional stability so the seal remains flexible under heat cycling.

• Includes one valve cover gasket, four oil seals, and ten washers for a complete reseal.
• NBR/ACM rubber resists both high- and low-viscosity oils to prevent swelling or degradation.
• Lab-tested at elevated temperatures (150°C×70h & 180°C×4h) to validate durability.

Will this fit my vehicle and how precise is the fit?

The A-Premium kit is manufactured to OEM-equivalent dimensions and references original part numbers for compatibility. It fits specific Toyota models listed, so verify engine type and year before ordering to ensure the seal aligns with the valve cover bolt pattern and passages.

• Compatible with Toyota 4Runner 1996–2000 L4 2.7L, T100 1994–1998 L4 2.7L, Tacoma 1995–2004 L4 2.4L and 2.7L.
• Size matches original valve cover seal; designed for direct replacement without modification.
• Reference numbers included: 1121375030, VS50512R for cross-checking fitment.

What materials and temperature/oil resistances should I expect?

The seals are molded from Nitrile Butadiene Rubber (NBR) and ACM blends chosen for automotive sealing applications. They tolerate a wide service range and maintain sealing integrity against common engine oils and heat exposure found in normal operation.

• Material: NBR/ACM rubber with black finish for durability and oil resistance.
• Operating temperature range: -20°C to 150°C for continuous service.
• Formulated to resist breakdown from high- and low-viscosity oils.

How long does the kit last and what warranty comes with it?

Longevity depends on driving conditions and proper installation, but the material selection and lab testing indicate solid long-term performance compared with stock rubber components. A-Premium backs the product with a one-year warranty to cover defects in materials and workmanship.

• Rigorous lab-tested performance under heat to simulate engine conditions.
• 1-year limited warranty against manufacturing defects.
• Designed to match original part durability when installed correctly.

Who is this for: This gasket set is aimed at DIY mechanics and professional technicians repairing oil leaks on compatible Toyota 4Runner, T100, and Tacoma vehicles. It’s useful for owners replacing worn valve cover seals during routine maintenance or when diagnosing oil seepage, and for workshops that need a ready-to-install, OEM-fit replacement kit with proven oil and heat resistance.
