Review SUBARU Ascent Side Left Engine Cylinder Block Head Camshaft Oem fits 2019–2025

The **Subaru 11104807 engine cylinder block head assembly (2019 2025 FA20F engine, specifically for the Subaru Ascent)** is a precision-engineered component designed to deliver the high performance and reliability expected from Subaru s advanced FA20F inline-four architecture. This critical part integrates the **cylinder head, intake manifold, exhaust manifold, and camshaft assembly** into a single, seamless unit, ensuring optimal airflow, combustion efficiency, and power output. Crafted from high-grade aluminum alloy, the head features **four intake and exhaust ports per cylinder**, paired with **dual overhead camshafts (DOHC)** that drive high-lift, variable valve timing (VVT) solenoids for dynamic throttle response and fuel economy. The **intake manifold** is engineered with smooth, high-flow passages to maximize air intake, while the **exhaust manifold** is designed to minimize backpressure, enhancing exhaust scavenging and turbocharger efficiency in forced-induction applications. The **camshafts** are precision-machined with hardened lobes and integrated oil passages to maintain consistent lubrication under high-stress conditions, contributing to the engine s longevity and durability. This assembly is a direct-fit replacement for the stock unit, ensuring compatibility with the Ascent s **2.0L turbocharged engine**, and is built to meet or exceed OEM specifications, including proper sealing surfaces for the head gasket and secure mounting points for the valve cover and intake plenum. Whether for a routine replacement or an upgrade to restore factory performance, this component is essential for maintaining the Ascent s signature blend of torque, responsiveness, and reliability across its model years.

### **Pros and Cons of Buying a Subaru 11104807 (2019-2025 FA20 Engine Cylinder Head with Camshaft)**

1. **OEM Quality and Reliability** This part is a genuine Subaru replacement, ensuring proper fit, function, and compatibility with the FA20 engine (used in the 2019-2025 Subaru Ascent). Subaru s engine components are known for durability, especially in their horizontally opposed (boxer) engines.

2. **Direct Fitment** The part number (11104807) is designed specifically for the FA20 engine, meaning no modifications or additional adapters are required. This reduces installation complexity and potential for errors.

3. **Prevents Engine Damage** A failing cylinder head or camshaft can lead to catastrophic engine failure, including warped heads, seized valves, or even a blown engine. Replacing these components proactively avoids costly repairs.

4. **Improves Performance and Efficiency** A properly functioning cylinder head and camshaft ensure optimal combustion, fuel efficiency, and power output. Worn components can lead to misfires, reduced horsepower, and increased emissions.

5. **Warranty Coverage** If purchased from an authorized Subaru dealer or a reputable aftermarket supplier, this part may come with a warranty, providing peace of mind against defects.

6. **Compatibility with Aftermarket Upgrades** Since this is an OEM part, it works seamlessly with aftermarket modifications (e.g., cold air intakes, performance exhausts) without compatibility issues.

7. **Long-Term Cost Savings** Replacing a failing head or camshaft early prevents secondary damage (e.g., to pistons, valves, or the crankshaft) that could arise from prolonged neglect.

---

1. **High Cost** OEM parts from Subaru are expensive compared to aftermarket alternatives. The cylinder head and camshaft assembly for the FA20 engine can cost several hundred dollars, making this a significant upfront investment.

2. **Labor-Intensive Installation** Replacing a cylinder head requires removing the engine from the vehicle (or performing a full tear-down in some cases), which involves significant labor. This can add thousands of dollars to the repair cost if done professionally.

3. **Potential for Counterfeit Parts** If purchasing from an untrusted source, there is a risk of receiving a fake or low-quality part that fails prematurely. Always buy from authorized dealers or well-reviewed suppliers.

4. **Limited Availability of Aftermarket Alternatives** While aftermarket cylinder heads exist, finding a high-quality, FA20-specific camshaft assembly may be difficult. Some aftermarket parts may not match OEM tolerances or durability.

5. **Time-Consuming Repair** The process of disassembling the engine, inspecting other components (e.g., gaskets, seals), and reassembling it can take days, especially for DIYers without mechanical experience.

6. **Risk of Hidden Damage** If the engine has been previously damaged (e.g., from overheating or improper maintenance), replacing just the head and camshaft may not fully resolve underlying issues, leading to recurring problems.

7. **Depreciation Consideration** If the vehicle is older or has high mileage, the cost of this repair may outweigh the vehicle s remaining value, making it a less practical investment.

Buying a genuine Subaru 11104807 cylinder head and camshaft assembly for the 2019-2025 FA20 engine is a **highly recommended** choice if the part is failing or showing signs of wear. The long-term reliability, performance benefits, and prevention of catastrophic engine failure justify the cost for most owners who prioritize durability and longevity. However, the expense and labor requirements make this a significant undertaking, particularly for older or high-mileage vehicles.

For those on a tighter budget, a thorough inspection of the engine s condition (including other components like gaskets, valves, and seals) should be performed before committing to the repair. If the rest of the engine is in good shape, this replacement is a wise investment. If the vehicle has extensive wear or is nearing the end of its useful life, the cost may not be justified.

- **If the engine is otherwise healthy and the vehicle is a priority:** Proceed with purchasing the OEM part (11104807) and have it installed by a trusted mechanic or Subaru specialist.

- **If budget is a concern:** Explore aftermarket options (with caution) or consider whether the repair is worth the investment in the vehicle s remaining lifespan.

- **Always verify the source:** Buy from an authorized Subaru dealer or a reputable supplier with a warranty to avoid counterfeit parts.

- **Inspect other components:** While replacing the head and camshaft, check for related issues (e.g., timing belt, water pump, gaskets) to prevent future problems.

For most Subaru owners who value their vehicles performance and longevity, this is a **necessary and worthwhile repair** when symptoms of head or camshaft failure are present.
