Review SUBARU Passenger Right Cylinder Head Assembly Oem 2.2l fits LEGACY 1990–1995

The **Subaru 298741 cylinder head (Passenger Side, 2.2L, 1990 1995)** is a meticulously engineered component designed to deliver peak performance and reliability within the iconic boxer engine architecture that defines Subaru s legendary driving dynamics. Crafted from high-quality cast aluminum, this precision-machined head features a robust design optimized for the 2.2L horizontally opposed (flat) four-cylinder engine found in models like the Subaru Justy, Loyale, and early-generation Legacy. The head is engineered with four intake and four exhaust valves per cylinder, arranged in a 20-degree V configuration to enhance airflow and combustion efficiency, a hallmark of Subaru s boxer engine philosophy. The intake ports are generously sized to maximize volumetric efficiency, ensuring a smooth and powerful induction process, while the exhaust ports are contoured to minimize backpressure and improve scavenging critical for maintaining the engine s characteristic smoothness and responsiveness. The head is equipped with a single overhead camshaft per bank, driven by a timing chain that delivers precise valve actuation, reducing wear and ensuring consistent performance over the long term. The combustion chambers are shaped to promote optimal fuel-air mixture distribution, reducing knock sensitivity and allowing for higher compression ratios when tuned appropriately. This cylinder head also incorporates a robust valve spring system, including helical valve springs and retainers, designed to handle the high RPM potential of the 2.2L engine while maintaining reliable valve closure under demanding conditions. The head s design includes integrated spark plug bosses and a precise valve cover mounting surface, ensuring a secure and leak-free installation. Whether restoring a classic Subaru or upgrading an existing engine, this passenger-side cylinder head is a critical component that contributes to the engine s signature balance, torque, and durability, embodying the blend of Japanese engineering precision and performance-driven innovation that Subaru enthusiasts have come to admire.

### **Pros and Cons of Buying a 1990-1995 Subaru 2.2L Passenger-Side Cylinder Head (Part # 298741)**

1. **Common and Widely Available** The 2.2L EA82 engine (used in early Subarus like the Legacy, Outback, and Justy) is a well-documented platform, meaning parts like this cylinder head are easy to source from both OEM and aftermarket suppliers. You won t struggle finding replacements if needed.

2. **Proven Reliability (When Maintained)** The EA82 engine is known for durability when properly serviced. Many of these engines last well over 200,000 miles with regular maintenance, including head replacements when necessary.

3. **Budget-Friendly Replacement** Compared to modern high-performance cylinder heads, this part is relatively inexpensive, especially if sourced from a used or rebuilt supplier. New OEM heads are often available for under $200 $300, while aftermarket or rebuilt units can be even cheaper.

4. **Simple Design** The 2.2L head is a pushrod design with fewer components than modern overhead-cam engines, making it easier to work on for DIYers. Common issues (like valve stem seals or rocker arms) are straightforward to address.

5. **Compatibility with Modifications** The EA82 is a popular platform for tuning, and many aftermarket parts (intake manifolds, headers, fuel systems) are designed to work with it. A fresh head can help restore performance after modifications.

6. **Used/Rebuilt Options Available** If buying used, you can often find heads that have been professionally rebuilt or inspected, reducing the risk of hidden damage (like cracked decks or warped surfaces).

7. **Subaru s Early Reliability** While later Subarus gained a reputation for head gasket failures, the 2.2L EA82 is less prone to catastrophic head gasket blowouts compared to the later FB/FB20 engines. This makes it a more stable choice for long-term builds.

1. **Potential for Wear or Damage** Even if the head appears intact, it may have internal wear (valve guides, seats, or springs), warping, or exhaust port erosion. Without a thorough inspection (or a rebuilt unit), you risk hidden problems.

2. **Age-Related Issues** Parts from this era (1990 1995) may have been manufactured with less stringent quality control than modern components. Rust, corrosion, or manufacturing defects could be present.

3. **Limited Aftermarket Support for Specific Problems** While the engine is common, some niche issues (like rare valve spring failures or lifter wear) may not have widely available fixes. Researching common failures for this engine is wise.

4. **Mismatched Parts Risk** If buying a used head, ensure it matches your engine s specifications (e.g., porting, valve sizes, or bolt patterns). Some early 2.2L heads may have slight variations in design.

5. **Labor Intensity** Removing and installing a cylinder head requires skill, especially if the engine has been neglected. Gasket surfaces must be cleaned thoroughly, and bolt torque specs must be followed precisely to avoid warping.

6. **Fuel System Compatibility** The 2.2L EA82 runs on carbureted or early fuel-injected systems (depending on model year). If your project involves modern fuel systems (e.g., EFI upgrades), you may need additional modifications beyond just the head.

7. **Environmental and Safety Concerns** Older heads may contain asbestos in gaskets or other materials. If handling them, proper ventilation and safety gear (gloves, mask) are recommended.

Buying a **1990 1995 Subaru 2.2L passenger-side cylinder head (part #298741)** is a practical choice for restorers, DIY mechanics, and enthusiasts working on classic Subarus. The part is **affordable, widely available, and compatible with a proven engine design**, making it a solid option for rebuilding or replacing a worn head. However, **buyers must exercise caution** ensuring the head is either **new, professionally rebuilt, or thoroughly inspected** is critical to avoid hidden issues like warping, internal wear, or corrosion.

- **New or rebuilt heads** from reputable suppliers (e.g., Summit Racing, RockAuto, or trusted local shops).

- **Matching the head to your engine s exact specifications** (check valve sizes, porting, and bolt patterns).

- **Proper preparation** (cleaning gasket surfaces, using high-quality gaskets, and following torque specs).

If you re **not comfortable with engine work**, consider hiring a mechanic to install it, as improper handling can lead to costly mistakes.

**Purchase a new or professionally rebuilt 2.2L cylinder head** from a trusted source to ensure reliability. If buying used, **inspect it closely** (look for cracks, warping, or internal damage) or have it professionally inspected before installation. For most projects, the **cost savings of a used head are outweighed by the risk of hidden problems**, making a new or rebuilt unit the safer bet.

For long-term performance, pair the head with **proper maintenance** (regular valve adjustments, gasket replacement, and fuel system upgrades if needed). The 2.2L EA82 remains a **great engine for classic Subaru builds**, and a fresh head will help restore its reliability and performance.
