1. Subaru Valve Cover Gasket Set (Left & Right) – Genuine Replacement
| Brand | Subaru |
|---|---|
| Manufacturer Part Number | 13270AA162 & 13272AA094 |
| Item Weight | 1 pounds |
This is a genuine Subaru valve cover gasket set intended as a direct factory-quality replacement for the left and right valve covers. It is used when valve cover leaks develop or during routine service that requires removing the valve covers, and because it is a manufacturer part it is made to match the original fit and sealing surfaces. The set lists the manufacturer part numbers for straightforward identification and replaces both sides in one purchase, which simplifies repair jobs. Practical benefits include correct fitment, predictable sealing performance, and reduced risk of oil leaks when installed properly. Limitations are that this is a basic gasket set without additional grommets or hardware beyond the listed parts, and buyers should confirm exact engine compatibility before installation. Installation still requires standard mechanical access and care to torque sequences and sealing surfaces.
Best for: Reliability-focused owners who prioritize factory-fit replacement parts for long-term leak prevention and correct fit during maintenance or repairs.
Less Ideal for: Buyers looking for a do-it-all overhaul kit with extra seals, bolts, or upgraded materials should consider comprehensive aftermarket kits instead.

Choosing the Right Subaru Impreza Valve Cover Gasket: Key Factors to Consider
Material and Construction
The gasket material determines how well it resists heat, oil, and vibration over time. Rubberized elastomers, silicone, and multi-layer composite gaskets each age differently; choose a material that tolerates the engine bay temperatures common to Subaru Impreza models.
Construction quality affects how the gasket maintains shape and sealing pressure after repeated thermal cycles. A uniformly molded gasket reduces the risk of hard spots or thin areas that lead to seepage. Consider whether the gasket includes integrated seals at critical ports or raised sealing beads to improve longevity.
Fitment and Dimensional Accuracy
Correct fitment to the Subaru Impreza valve cover and head is essential to form a continuous seal. Even small deviation in hole alignment or overall shape can create stress points where oil can weep or drip.
Look for gaskets with precise molding tolerances and clear fitment references. A gasket designed specifically for the Subaru Impreza reduces the chance of trimming, modification, or layered shimming during installation, which can compromise the seal.
Sealing Design and Port Coverage
Analyze how the gasket seals around cam cover bolts, spark plug wells, and oil passages. Gaskets that incorporate raised sealing ridges or thicker cross-sections at high-stress areas better resist pressure and flexing that cause leaks.
Complete port coverage around spark plug wells is important to prevent oil ingress into ignition components. Evaluate whether the gasket design isolates oil passages from combustion or electronic areas to reduce failure points.
Durability Against Oil and Heat
Exposure to hot engine oil and elevated underhood temperatures accelerates gasket degradation. Materials treated to resist oil swelling and heat embrittlement will typically last longer on Subaru Impreza engines.
Ask whether the gasket material can withstand repeated heating cycles without significant hardening or cracking. Durability affects the interval between replacements and the likelihood of secondary damage from leaking oil.
Ease of Installation and Serviceability
A gasket that aligns easily and tolerates typical torque application reduces installation time and the risk of improper sealing. Features like indexed bolt holes or flexible corners make positioning straightforward during a DIY replacement.
Consider whether the gasket can be reused in limited circumstances or if it requires full replacement at each service. Also evaluate how tolerant the design is to slight variations in valve cover flatness and bolt torque differences, since real-world conditions often deviate from ideal.
Compatibility with Fastener and Torque Requirements
Bolt pattern, head clearance, and required torque specifications influence how the gasket performs once installed. A gasket must maintain seal integrity at the clamping forces specified for Subaru Impreza valve cover bolts.
Selecting a gasket that matches the intended clamping range helps prevent over-compression or insufficient sealing. Understand the recommended torque specs for the vehicle and whether the gasket material reliably seals within that range to avoid leaks or damage.
FAQ
What are common symptoms of a failing Subaru Impreza valve cover gasket?
Common signs include oil visible around the valve cover edges, oil collecting under the vehicle or on nearby engine components, and a burning oil smell if oil contacts hot surfaces. You may also notice fouled spark plugs or misfires if oil seeps into spark plug wells. Symptoms can vary in severity and often appear gradually.
How long does a typical valve cover gasket last on a Subaru Impreza?
Lifespan depends on material, driving conditions, and maintenance. Under normal conditions, a good-quality gasket often lasts many years, but heat cycling and oil exposure eventually cause hardening or cracking. Regular inspections during routine service help identify wear before significant leaks occur.
Can I replace the valve cover gasket myself?
Many owners with basic mechanical skills can replace a valve cover gasket at home, since the job usually involves removing the cover, cleaning mating surfaces, and reinstalling with correct torque. Proper cleaning and following torque specs are important to prevent leaks. If you are unsure about access, sealing surface condition, or torque procedures, seek professional help.
Will a small valve cover gasket leak cause engine damage?
A minor leak by itself rarely causes immediate engine failure, but unchecked leaks can lead to oil loss, contamination of ignition components, and potential fire hazards if oil contacts hot exhaust parts. Addressing leaks early prevents secondary issues and reduces the risk of more extensive repairs.
How can I check fitment before purchasing a gasket?
Verify that the gasket listing or packaging explicitly references the Subaru Impreza model year and engine variant to ensure matching bolt patterns and port locations. Check measurements or schematics if available and confirm that spark plug well coverage and mounting hole spacing align with your engine's valve cover. Avoid parts with only generic fitment claims.
How We Chose the Best Subaru Impreza Valve Cover Gasket
We focused on attributes that directly affect long-term sealing and serviceability on the Subaru Impreza. Key evaluation criteria included gasket material and thickness to resist heat and oil deterioration; molding precision and dimensional accuracy for consistent fit against the valve cover and cylinder head; compatibility with the Subaru Impreza valve cover geometry and fastener pattern to avoid leak paths; resistance to oil and coolant exposure where applicable; and ease of installation including whether the design tolerates typical torque variances.We excluded products lacking clear fitment information for the Subaru Impreza or those that used unspecified or non-durable materials. Items intended only as universal or generic repairs without specific guidance for Subaru Impreza applications were not considered. Our selections favored parts that balance longevity, reliable sealing, and straightforward replacement for typical maintenance scenarios.
Our full evaluation process is outlined in our review methodology.
Conclusion
When selecting a valve cover gasket for a Subaru Impreza, prioritize correct fitment, durable material, and a sealing design that protects critical ports like spark plug wells. These factors determine how well the gasket resists oil exposure, heat cycles, and the typical stresses of driving.Balance ease of installation and compatibility with the vehicle-specific torque and fastener layout. Addressing symptoms early and choosing a gasket built for repeatable sealing will reduce the chance of recurring leaks and simplify future maintenance.
