| Material | Rubber |
|---|---|
| Model | VS50900R |
| Manufacturer | Fel-Pro |
| Unit Count | 1.0 Count |
The Fel-Pro VS50900R is a complete valve cover gasket set designed for Nissan/Infiniti VQ engines used in vehicles such as the Infiniti Q50. It provides the main cork-rubber valve cover gasket and related seals so you can replace leaking valve cover seals and stop oil entering spark plug wells or dripping on the exhaust. The kit is formulated to conform to imperfect sealing surfaces and is marketed as including every part needed for the repair unless otherwise noted. In practice this makes it useful for DIY repairs or shop work where the original gasket has failed. Customers report it fits like a factory replacement and holds up on the road, though some installers find the gasket profile slightly thin for easy placement and use a small amount of RTV to hold it in the groove during installation. One buyer noted an incomplete shipment, so double-check contents on arrival. If you want a straightforward, application-specific replacement that mirrors factory fit and helps cure common Q50 valve cover leaks, this set covers the basics without aftermarket modification.
Best for: Balanced buyers who want a factory-quality, application-specific replacement to reliably fix valve cover leaks on their Infiniti Q50 without upgrading to performance or racing parts.
Less Ideal for: If you need a heavy-duty or modified sealing solution for track use or extreme conditions, choose a performance-grade gasket set instead.
- Designed specifically for Nissan/Infiniti VQ engine applications including Q50 so fitment aligns with factory specifications
- Cork-rubber formulation conforms to imperfect sealing surfaces for improved leak resistance
- Includes the parts needed for a valve cover gasket repair in one kit
- Proven on-vehicle testing and real-world validation mentioned by the manufacturer
- Gasket profile can be slightly thin which may require a few drops of RTV to keep it in place during installation

Verdict A straightforward, factory-quality valve cover gasket kit that reliably addresses common Q50 valve cover leaks with minimal fuss.
Choosing the Right Infiniti Q50 Engine Gasket Set: Key Factors to Consider
Gasket Material and Construction
The material and how gaskets are made directly affect their ability to seal under heat, pressure, and chemical exposure. Multi-layer steel, composite, and high-temperature elastomer faces each have different strengths for sealing head surfaces, intake runners, and oil passages.
Material choice also impacts longevity and resistance to warping or degradation when exposed to coolant and oil. Look for materials compatible with the engine’s operating temperatures and fluids to reduce the risk of repeat failures.
Completeness of the Kit
A complete kit should include all gaskets and seals needed for the scope of the repair, such as head gaskets, intake and exhaust gaskets, valve cover gaskets, oil pan gaskets, and all relevant O-rings and seals. Incomplete kits force you to source missing parts separately, increasing downtime and the chance of mixing mismatched materials.
Completeness is especially important during engine overhauls or head gasket jobs where multiple sealing surfaces are disturbed. Confirm the kit covers the specific Infiniti Q50 engine components you will remove or replace.
Fitment Accuracy
Accurate dimensions and hole alignment are crucial to avoid leaks and reduce installation time. Poor fitment can lead to misaligned bolt holes, gaps at sealing surfaces, or interference with oil and coolant passages.
Kits that match factory specifications or explicitly state OEM-equivalent tolerances generally make installation smoother and lower the chance of gasket failure after reassembly.
Resistance to Heat and Fluids
Engine gaskets are exposed to fluctuating temperatures and a variety of fluids. Materials that resist heat-related breakdown, coolant contamination, and oil swelling will maintain a seal longer. Some gasket types incorporate coatings or designs that improve resilience to thermal cycling and chemical exposure.
Consider the engine’s typical operating range and whether additional treatments or specific elastomers are recommended for lasting performance.
Included Hardware and Instructions
Some gasket sets include new seals, O-rings, and sometimes bolts or washers that should be replaced during service. Including these parts reduces the risk of reusing worn or stretched fasteners that can compromise the seal. Clear installation guidance and torque specifications, when provided, help ensure proper assembly.
Absence of necessary hardware often leads to incomplete repairs or unintended rework, so check what is included before starting a job.
Compatibility With Repair Scope
Different repairs require different levels of kit coverage. A head gasket replacement requires head gaskets plus related seals, whereas a full engine overhaul calls for a very comprehensive gasket and seal package. Matching the kit to the planned work avoids unnecessary part purchases or surprises during disassembly.
Plan the repair steps and confirm the kit includes gaskets for every component you will service to ensure a single, consolidated repair session.
FAQ
How do I know which gasket set fits my Infiniti Q50 engine?
Check the kit details for explicit Infiniti Q50 compatibility and the engine code or model year range. Verify that included gaskets correspond to the components you will service. When in doubt, compare hole patterns and listed fitment notes to your vehicle’s engine specifications.
Can I reuse old gaskets when replacing engine components?
Reusing gaskets is usually not recommended, especially for critical seals like head gaskets and valve cover gaskets. Old gaskets can be compressed, cracked, or hardened, which increases the risk of leaks. Replace gaskets and seals as part of any repair that disturbs mating surfaces.
What signs indicate I need a full gasket set instead of a single gasket?
If you are removing major engine components such as the cylinder head, intake manifold, or oil pan, a full gasket set is often prudent. Multiple seals can be disturbed during disassembly, and replacing all related gaskets helps prevent future leaks. Persistent or multiple-site leaks are another indicator that a comprehensive kit may be needed.
Do higher-cost gasket sets always mean better sealing performance?
Cost can reflect material quality and completeness, but it is not the sole indicator of performance. Evaluate material type, construction, fitment accuracy, and included hardware. A well-specified kit that matches the repair scope and uses appropriate materials is more important than price alone.
Are specialty seals or coatings necessary for high-mileage Infiniti Q50 engines?
Older or high-mileage engines may benefit from gaskets and seals designed for enhanced sealing, such as reinforced materials or specific elastomers that resist oil swelling. These options can compensate for slightly irregular surfaces, but proper surface preparation and mechanical inspection are still essential.
How We Chose the Best Infiniti Q50 Engine Gasket Set
We focused on options that specifically list compatibility with the Infiniti Q50 and that include the core gaskets and seals commonly replaced during engine work. Key evaluation criteria included gasket material and construction, which influence durability and sealing under heat and pressure; completeness of the kit, meaning whether it contains all head, intake, exhaust, valve cover, and oil pan gaskets plus necessary seals and O-rings; dimensional accuracy and OEM-equivalent fitment to reduce installation adjustments; and corrosion and chemical resistance for longevity around coolant and oil. We also considered the presence of robust sealing surfaces and proper torque specification guidance where provided. Exclusions: we excluded generic universal kits that do not specify Infiniti Q50 fitment, single-gasket items that would require sourcing many additional parts, and any listings that omit essential seals. The result is a list emphasizing long-term reliability and minimized rework for common Infiniti Q50 engine service tasks.
Our full evaluation process is outlined in our review methodology.
Conclusion
When selecting an Infiniti Q50 engine gasket set, prioritize material compatibility, fitment accuracy, and kit completeness relative to the repair you plan. Consider whether the kit includes all seals and necessary hardware to avoid repeat disassembly. Balance durability and the scope of work: choose multi-layer or high-temperature materials for critical sealing surfaces and pick a kit that matches the extent of service to minimize downtime and future leaks.
