Sorello Valve Cover & Intake Manifold Gasket Set MS97143 VS50770R — Direct-Fit, Oil-Resistant for Infiniti/Nissan

The Sorello MS97143 VS50770R Engine Valve Cover Gasket Set is a direct-fit replacement kit engineered to restore a reliable oil seal for compatible Infiniti and Nissan V6 engines.

If your vehicle is showing signs of oil seepage around the valve cover or you’re rebuilding an engine, this complete gasket set provides the precise shapes and materials needed to recreate the factory sealing surfaces. Sorello designed the components to match original equipment dimensions and to resist oil, heat, and vibration found in daily driving and performance conditions.

Which vehicles and part numbers does this gasket set replace?

This gasket kit corresponds to OE references MS97143 and VS50770R and fits a variety of Infiniti and Nissan models with the same VQ-series family engines. Always confirm fitment by checking the part numbers and your vehicle year/model before ordering to ensure compatibility.

• OE numbers: MS97143, VS50770R
• Infiniti: 2013 JX35, 2014–2015 QX60
• Nissan: 2007–2015 Altima, 2009–2020 Maxima, 2009–2024 Murano
• Also fits: 2015 Pathfinder, 2011–2017 Quest

What materials and design features help prevent leaks?

Sorello uses a rubberized compound and precision molding to ensure consistent cross-section and sealing performance. The material resists oil swelling and compresses to fill microscopic imperfections, creating a stable barrier under changing temperatures and engine loads.

• Durable rubberized compound formulated for oil resistance
• Accurate mold profiles that match OEM sealing surfaces
• Compression characteristics that maintain seal under thermal cycling
• Includes both valve cover and intake manifold gasket components for a comprehensive reseal

How difficult is installation and what does the kit include?

The gaskets are manufactured to original specifications for a bolt-on replacement, making them suitable for professional shops and competent DIYers. Basic engine teardown around the valve cover is required; following torque specs and proper surface cleaning will help ensure a long-lasting seal.

• Direct replacement—no trimming or modification needed
• Package contains: 1 intake manifold gasket set and 1 engine valve cover gasket set
• Installation tip: clean mating surfaces and follow factory torque sequence
• Compatible with standard hand tools; consider replacing related seals and fasteners while open

Will this reduce engine noise or help with heat isolation?

While the primary role is sealing oil, the gasket compound also dampens vibration and provides some thermal isolation between the valve cover and head. This can reduce certain resonant noises and limit heat transfer from internal components to the cover, contributing to quieter operation.

• Noise reduction through vibration damping material
• Thermal isolation that minimizes external heat transfer
• Helps maintain a stable operating environment around the valvetrain

Who is this for: The Sorello MS97143 VS50770R Valve Cover Gasket Set is intended for owners and mechanics servicing Infiniti QX60/JX35 and Nissan Altima, Maxima, Murano, Pathfinder, and Quest models that use the specified OE numbers. It's a good choice for routine repairs, leak remediation, and engine reassembly projects where a reliable, OEM-dimension gasket and intake manifold seal are required. Confirm your vehicle’s compatibility before purchase and replace related seals and components where appropriate to maximize longevity.
