| Brand | DNJ |
|---|---|
| Model | Valve Cover Gasket |
| Item model number | VC663G |
The DNJ VC663G valve cover gasket set is a direct-fit replacement designed for 3.7L VQ37VHR engines such as the Infiniti G37 and Nissan 370Z. It replaces the seal between the valve cover and cylinder head to stop oil leaks and restore proper engine sealing. The kit is described as made from premium materials for heat and pressure resistance and includes spark plug tube seals and grommets where required for a complete installation. In practical use this type of gasket set is typically used during valve cover removal, routine maintenance, or when diagnosing oil seepage around the top of the engine. The main benefits are straightforward fitment for the specified engines and a full kit approach that reduces the need to source individual seals. The limitation is that compatibility is strictly for the listed VQ37VHR applications, so confirm engine code and year before buying, and as with most aftermarket gaskets some buyers may prefer a factory-brand part for long-term peace of mind in high-mileage engines.
Best for: Balanced all-round buyers who want a straightforward, vehicle-specific replacement gasket set to stop leaks and complete valve cover service without hunting down multiple parts.
Less Ideal for: Buyers seeking parts for engines other than the VQ37VHR or those insisting on factory-branded components for restoration-level authenticity should consider alternatives.

Choosing the Right Infiniti G37 Valve Cover Gasket: Key Factors to Consider
Material and Durability
The gasket material determines how well it resists oil, heat, and age-related cracking. High-quality materials maintain flexibility and compressive properties across temperature cycles, which keeps the seal tight and reduces the chance of leaks.
A durable compound also stands up to oil additives and solvent exposure that can degrade inferior materials. When a gasket remains supple, it conforms to surface irregularities and maintains a consistent seal even after repeated thermal expansion and contraction.
Fitment and Compatibility
Accurate fitment is essential for a clean installation and reliable sealing. A gasket that matches the Infiniti G37 bolt pattern, sealing ridges, and PCV or oil-fill openings reduces the need for modification and lowers leak risk.
Confirming fitment also saves time during installation and helps ensure that bolts preload the gasket evenly. Poorly matched parts can leave gaps or over-compressed areas that lead to oil seepage or premature failure.
Sealing Design and Profile
Gasket cross-section and sealing features affect how pressure is distributed along the mating surfaces. Raised beads, multi-layer construction, or reinforced lips can improve initial sealing and long-term retention of compression.
A well-designed profile compensates for minor surface imperfections and helps maintain a continuous seal under vibration and thermal cycling. The right design reduces the chance of intermittent leaks that are hard to diagnose.
Included Hardware and Accessories
Some gasket kits include replacement grommets, seals, or bolt washers that are often necessary when reusing old hardware. Having these items included simplifies installation and can prevent common failure points caused by degraded ancillary components.
Replacing worn grommets and seals at the same time ensures the entire sealing system is refreshed, increasing the likelihood of a successful, long-lasting repair.
Ease of Installation
Think about how the gasket handles during install and how straightforward the fitment is. Softer, more pliable materials are generally easier to position correctly, while rigid profiles may require more care to avoid misalignment.
Also consider whether the gasket requires additional sealants or RTV in specific areas. Clear installation compatibility with factory torque specs and accessible mounting points makes the job faster and reduces the risk of overtightening or underloading bolts.
Long-Term Performance and Maintenance
Assess how the gasket will perform across normal driving cycles and routine maintenance events. Durable gaskets should resist shrinkage and maintain sealing abilities over many heat cycles and oil changes.
Consider whether the design allows for occasional inspections without full disassembly and whether replacement intervals align with typical maintenance schedules. A gasket that requires minimal follow-up after installation reduces downstream labor and inconvenience.
How We Chose the Best Infiniti G37 Valve Cover Gasket
Our selection process focused on components that offer dependable sealing and straightforward installation for the Infiniti G37. We prioritized gaskets made from durable materials that resist oil, heat, and age-related hardening. Fitment accuracy was a key filter, favoring parts designed to match factory bolt patterns and accommodate PCV ports and mounting surfaces. We evaluated sealing performance based on material composition and design features that maintain compression over time. Ease of installation also mattered, including gasket pliability and whether additional seals or grommets are required. Finally, we considered compatibility with recommended torque specifications and common maintenance procedures.We excluded products that lacked clear vehicle-specific fitment information, gaskets made from low-density or non-heat-resistant compounds, and parts without documented sealing design features. The resulting list emphasizes longevity, correct fit, and installer-friendly properties rather than cost alone.
Our full evaluation process is outlined in our review methodology.
FAQ
What are common symptoms of a failing valve cover gasket on an Infiniti G37?
Common signs include visible oil seeping around the valve cover, oil on spark plug wells, a burning oil smell when the engine is hot, and occasionally blue smoke from the exhaust if oil reaches hot components. You may also notice lower oil levels between changes. These symptoms often indicate the gasket is no longer providing a full seal and should be inspected.
Can I replace the valve cover gasket myself on an Infiniti G37?
Many owners perform this repair with basic hand tools and a torque wrench. The job usually involves removing components that obstruct the cover, cleaning the mating surfaces, and following proper torque sequences. It often depends on your comfort with engine work and access to service information about bolt torque specs and sequence.
Do I need to replace other parts when changing the valve cover gasket?
It is often wise to replace related seals and grommets that show wear, since these components are common failure points. If the kit does not include replacement hardware, consider swapping degraded grommets, PCV grommets, or washer seals to ensure a complete and reliable seal. Neglecting these can lead to future leaks even with a new gasket.
What causes a valve cover gasket to start leaking oil?
Heat cycling, oil contamination, and age-related hardening are common causes of gasket failure. Over time, materials can become brittle or compressed, losing their ability to conform to mating surfaces. Engine vibration and improper bolt torque can also create uneven sealing pressure that promotes seepage.
Should I use sealant when installing a valve cover gasket?
Some designs require a small amount of sealant at specific corners or mating points, while others are intended to seal without any adhesive. Follow the manufacturer's guidance for the gasket type you are using and apply sealant sparingly only where indicated. Excessive sealant can block passages or prevent proper seating.
Conclusion
When choosing a valve cover gasket for an Infiniti G37, prioritize materials that resist heat and oil, accurate fitment to the factory mating surfaces, and a sealing profile that maintains compression over time. Include replacement grommets or seals when available and follow correct torque sequences during installation.Balancing durability, ease of installation, and the need to refresh ancillary hardware will lead to the most reliable repair and reduce the chance of repeat leaks.
