Review DNJ Graphite Cylinder Head Gasket Set Subaru Justy 1.2l

The **DNJ HGS705 Graphite Cylinder Head Gasket Set** is a precision-engineered, high-performance replacement designed specifically for the **1987 1994 Subaru Justy with the 1.2L EA81 engine**, ensuring a reliable and long-lasting seal for optimal engine performance. Crafted from **high-quality graphite composite material**, this gasket set is engineered to withstand the demanding thermal and mechanical stresses of daily driving, preventing leaks at critical interfaces such as the cylinder head, oil filter housing, and valve cover. Unlike conventional paper or fiber gaskets, DNJ s graphite formulation resists warping, swelling, or premature degradation, even under extreme heat or pressure, making it an ideal choice for both high-mileage vehicles and those subjected to aggressive driving conditions. The gasket set includes **all essential components**, including the **main cylinder head gasket, oil filter housing gasket, valve cover gaskets, and intake manifold gaskets**, ensuring a complete and hassle-free installation. Its **thin yet durable construction** minimizes the risk of oil or coolant leaks while maintaining proper compression, contributing to improved engine efficiency and longevity. Whether you're performing a routine maintenance overhaul or addressing a persistent leak, the **DNJ HGS705** delivers a dependable solution that meets or exceeds OEM standards, giving Subaru Justy owners confidence in their engine s reliability for years to come.

### Pros and Cons of buying a **DNJ HGS705 Graphite Cylinder Head Gasket Set for 1987 1994 Subaru Justy 1.2L**

1. **High-Quality Material** DNJ uses graphite-based gasket material, which is known for its durability, heat resistance, and ability to withstand pressure better than traditional fiber or paper gaskets. This reduces the risk of leaks and blowouts over time.

2. **Proper Fitment** The HGS705 is specifically designed for the 1.2L Subaru Justy (and related models like the Subaru Loyale and some early 1.3L models). This ensures a tight seal without distortion, which is critical for preventing oil or coolant leaks.

3. **Reliability for High-Mileage or Modified Engines** If your Justy has high mileage, a modified engine, or a history of overheating, a graphite gasket set is less likely to fail prematurely compared to cheaper alternatives.

4. **Easier Installation** Graphite gaskets are more forgiving during installation than some composite or paper gaskets, reducing the risk of damage if not perfectly aligned.

5. **Long-Term Performance** Graphite retains its sealing properties better under thermal cycling, making it a better choice for engines that experience temperature fluctuations.

6. **Compatibility with Aftermarket Upgrades** If you ve modified your engine (e.g., turbocharging, forced induction, or high-performance tuning), a graphite gasket set is more likely to handle increased stress.

7. **Widely Available and Trusted Brand** DNJ is a reputable manufacturer in the aftermarket, with a strong reputation for quality gasket sets. Parts are easy to find through online retailers and specialty auto shops.

1. **Higher Cost Compared to Basic Gaskets** Graphite gasket sets are more expensive than standard fiber or paper gaskets. For a budget-conscious buyer, this may be a drawback, especially if the engine hasn t shown signs of imminent failure.

2. **Requires Proper Installation** While graphite gaskets are forgiving, improper installation (e.g., uneven torque, cross-threading, or debris between surfaces) can still lead to leaks. This demands careful attention during the gasket change.

3. **Not Necessary for Minor Leaks** If your Justy is experiencing only minor oil or coolant leaks (e.g., a single bad gasket or a small crack), a graphite set may be overkill. In such cases, a cheaper replacement gasket or a DIY fix might suffice.

4. **Potential for Overkill on Stock Engines** If your engine is stock and running well with no history of overheating or mechanical stress, a graphite gasket set may not offer a significant advantage over a standard replacement set.

5. **Installation Complexity** Changing head gaskets is a labor-intensive job that requires removing the engine components, cleaning surfaces thoroughly, and ensuring proper torque specs. If you re not experienced with engine work, this could be a significant undertaking.

6. **Risk of Contamination During Removal** If old gasket material or debris is left on the head or block during removal, it can compromise the new gasket s seal. This requires meticulous cleaning, which some DIYers may overlook.

### **Conclusion and Recommendation**

- **Persistent leaks** (oil, coolant, or vacuum),

- **High mileage** (150,000 miles),

- **A history of overheating or mechanical stress**,

- **Plans for engine modifications** (turbo, tuning, etc.), or

- **A need for long-term reliability** despite the higher cost.

**However**, if your engine is running fine with no major issues and you re on a tight budget, a **standard replacement gasket set** (from a brand like Fel-Pro or Sealed Power) may be sufficient. These are significantly cheaper and still effective for basic replacements.

- **Go with the DNJ HGS705** if you want the best possible seal, plan to keep the car long-term, or have concerns about future engine stress.

- **Opt for a standard replacement set** if you re replacing a single failed gasket, the engine is in good condition, and you want to save money.

For most Justy owners, **proper installation is more critical than the gasket material itself**. If you re not comfortable with engine work, consider having a mechanic perform the replacement to ensure a perfect seal.
