Review BFO 2.0l Engine Crankshaft Kona 2017 2018 2019 2020 Crank fits ELANTRA

The **BF0 EL61O4 2.0L Engine Crankshaft** is a precision-engineered, high-performance component designed specifically for Hyundai s **2017 2020 Elantra and Kona models** equipped with the **Gamma II 2.0L GDI (Gamma Dual Injection) engine**, identified by the **EL61O4** engine code. Crafted from **high-grade forged steel**, this crankshaft is built to withstand the rigorous demands of modern automotive engines, ensuring durability, reliability, and optimal power delivery. The design incorporates **five main journals** and **six counterweights**, meticulously balanced to minimize vibration and enhance smooth operation, which is critical for maintaining engine longevity and performance. The **nodular graphite iron** construction provides exceptional strength and resistance to fatigue, making it ideal for high-revving applications and extended engine life. This crankshaft is a **direct replacement** for the original equipment (OEM) part, featuring the same **dimensions, tolerances, and machining specifications** as the factory unit, ensuring seamless integration with the engine s rod bearings, timing components, and harmonic balancer. Whether replacing a worn-out crankshaft due to excessive wear, failure, or as part of a **full engine rebuild**, this aftermarket part is engineered to meet or exceed OEM standards, delivering the same level of performance and efficiency as the original. Built to withstand the stresses of daily driving, aggressive acceleration, or even modified engine setups, this crankshaft is a trusted choice for mechanics, tuners, and enthusiasts seeking a **cost-effective yet high-quality upgrade** for their Hyundai Elantra or Kona.

### Pros and Cons of Buying a BFO EL61O4 2.0L Engine Crankshaft for 2017 2020 Hyundai Elantra/Kona

#### **Pros:**

1. **OEM Replacement Quality** The BFO (Build-From-Original) crankshaft is designed to match the original equipment specifications of the Hyundai EL61O4 engine, ensuring proper fitment, tolerances, and performance. This reduces the risk of premature wear or failure compared to aftermarket parts that may not meet exact OEM standards.

2. **Durability and Longevity** A high-quality crankshaft is critical for engine reliability. The BFO part is manufactured to withstand the stress of daily driving, reducing the likelihood of catastrophic failure (e.g., rod bearing failure or crankshaft snapping). This can extend the engine s lifespan, especially if the original crank was worn or damaged.

3. **Compatibility** The EL61O4 engine (used in 2017 2020 Elantra and Kona) is a known weak point in some vehicles, particularly due to oil pump issues and crankshaft wear. A replacement crankshaft ensures the engine runs smoothly without excessive vibration or noise, which can be a major concern in these models.

4. **Warranty and Support** Reputable BFO suppliers often provide warranties (e.g., 12 24 months) and customer support, giving you peace of mind if issues arise post-installation. This is more reliable than some no-name aftermarket parts with limited or no warranties.

5. **Prevents Further Damage** If the original crankshaft was damaged (e.g., from oil starvation, misfires, or excessive wear), replacing it prevents secondary damage to connecting rods, bearings, or the oil pump. This can save thousands in repair costs down the line.

6. **Performance Consistency** Unlike some aftermarket crankshafts that may be modified for performance gains (which can void warranties or cause issues), the BFO part is designed for stock reliability. This means your vehicle will maintain its intended power output without risking engine damage.

7. **Easier Installation** Since it s an OEM-replica part, it should fit seamlessly with existing components (e.g., bearings, rods, and oil pump). This reduces the need for additional modifications or adjustments during installation.

---

#### **Cons:**

1. **Cost** A BFO crankshaft is more expensive than generic aftermarket alternatives. Prices typically range between **$300 $600**, depending on the supplier and whether additional components (e.g., bearings, seals) are included. This can be a significant upfront cost, especially if other engine repairs (e.g., oil pump, timing belt) are also needed.

2. **Labor Intensity** Replacing a crankshaft is a labor-intensive job that requires disassembling the engine almost entirely. This means:

- **Engine removal or partial disassembly** (depending on the shop s approach).

- **Specialized tools** (crankshaft puller, bearing press, torque wrench).

- **Time-consuming** (typically **10 20 hours** of labor in a shop).

- If done at home, it requires mechanical expertise and patience.

3. **Potential for Hidden Issues** Even with a new crankshaft, other engine components (e.g., rods, bearings, oil pump) may be worn and need replacement. If these are overlooked, the engine may fail again shortly after installation. A **full engine rebuild** (including rods, bearings, and seals) is often recommended for long-term reliability.

4. **Availability and Lead Times** While BFO parts are widely available, lead times can vary. Some suppliers may take **1 4 weeks** to ship, which could delay repairs if you re in a hurry.

5. **Risk of Counterfeit Parts** Not all "BFO" or "OEM-replica" parts are genuine. Some sellers may market knockoffs as BFO to save costs. Always purchase from **reputable suppliers** (e.g., RockAuto, JEGS, or Hyundai-approved vendors) to avoid counterfeit or low-quality parts.

6. **Additional Costs** Beyond the crankshaft, you may need to budget for:

- **Bearings** (main and rod bearings, $100 $300).

- **Seals and gaskets** (crankshaft seal, oil pump seal, $50 $150).

- **Oil pump replacement** (often recommended, $150 $300).

- **Torque converter or transmission fluid flush** (if the engine was removed).

- **Labor costs** (varies by shop, but expect **$1,500 $3,500 ** for a full rebuild).

7. **Warranty Limitations** Even with a warranty on the crankshaft, Hyundai s powertrain warranty (if still active) may not cover labor or additional parts. You ll need to check your vehicle s warranty status and whether it covers engine repairs.

### **Conclusion and Recommendation**

Replacing the crankshaft in a **2017 2020 Hyundai Elantra/Kona with the EL61O4 2.0L engine** is a **necessary repair if the original crankshaft is damaged or severely worn**. The BFO EL61O4 crankshaft is the **best choice for reliability and longevity**, as it matches OEM specifications and reduces the risk of future failure. However, it is **not a standalone fix** a **full engine rebuild** (including rods, bearings, oil pump, and seals) is strongly recommended to ensure the engine runs smoothly for years to come.

#### **Recommendation:**

1. **Verify the Need for Replacement** Confirm that the crankshaft is indeed the issue (not just a bearing or oil pump problem). Symptoms like **knocking noises, oil consumption, or engine misfires** warrant further diagnosis (e.g., compression test, oil analysis, or a mechanic s inspection).

2. **Choose a Reputable Supplier** Purchase the crankshaft from a **trusted source** (e.g., RockAuto, JEGS, or a Hyundai-approved parts dealer) to avoid counterfeit parts. Look for parts with **serial numbers matching the OEM** and **warranty coverage**.

3. **Budget for a Full Rebuild** If the engine is showing signs of wear, **do not skimp** on additional components. A **complete rebuild** (crankshaft, bearings, rods, oil pump, seals) will cost **$1,500 $4,000 ** depending on labor and parts, but it will **extend the engine s life significantly** and prevent costly future failures.

4. **Consider Professional Installation** Unless you have **mechanical experience**, have the work done by a **reputable engine specialist or Hyundai dealer**. Improper installation can lead to **premature failure or damage**.

5. **Check Warranty Status** If your vehicle is still under **Hyundai s powertrain warranty**, explore whether they will cover the crankshaft replacement (though labor and additional parts may not be included).

6. **Alternative Options (If Budget is Tight)**

- **Remanufactured Engines**: Some shops offer **remanufactured EL61O4 engines** with warranties, which can be a cost-effective alternative to a full rebuild.

- **Aftermarket Crankshafts (With Caution)**: If the BFO part is too expensive, consider **high-quality aftermarket crankshafts** (e.g., from **Crankshafts.com, Eagle, or Fel-Pro**), but ensure they meet **EL61O4 specifications** and come with a warranty.

#### **Final Verdict:**

If your **2017 2020 Elantra/Kona s EL61O4 engine is showing crankshaft-related issues**, replacing it with a **BFO EL61O4 crankshaft is the best long-term solution**. However, **pair it with a full engine rebuild** to maximize reliability. If cost is a major concern, weigh the option of a **remanufactured engine** or explore warranty coverage before proceeding. **Do not delay repairs**, as a failed crankshaft can lead to **catastrophic engine damage**, which is far more expensive to fix.
