Review FORD Fomoco 2018 21 Lincoln 3.5l Engine Motor Left Cylinder Head Camshafts Oem fits NAVIGATOR

The **ML3E-6C094-EA 2018-2021 Lincoln Navigator 3.5L EcoBoost Engine Motor Left Cylinder Head Camshafts** is a precision-engineered, high-performance component designed exclusively for the iconic **Ford EcoBoost V6 platform**, specifically tailored to the **2018 through 2021 Lincoln Navigator** models equipped with the **3.5L EcoBoost engine**. These camshafts are integral to the left cylinder head assembly, playing a critical role in optimizing engine performance, fuel efficiency, and emissions compliance. Crafted from **high-grade forged steel**, these camshafts are engineered to withstand the extreme stresses of high-revving, turbocharged operation while maintaining optimal valve timing for peak power delivery. The **left cylinder head camshafts** feature a **lift profile** and **duration** finely calibrated to enhance both low-end torque and high-rpm responsiveness, ensuring a seamless power band that complements the Navigator s luxurious yet sporty driving dynamics. Whether installed in a stock application or as part of a performance upgrade, these camshafts contribute to smoother valve operation, reduced wear, and improved engine longevity. Built to meet **Ford s stringent OEM specifications**, they are a direct-fit replacement for the original equipment components, ensuring compatibility with the **EcoBoost intake and exhaust valve train systems**, including the **variable cam timing (VCT) solenoids** and **hydraulic lash adjusters**. Ideal for both **original equipment replacement (OER)** and **aftermarket tuning scenarios**, these camshafts are a key component for maintaining or enhancing the **3.5L EcoBoost engine s** reliability and performance across the full range of driving conditions, from highway cruising to spirited acceleration.

### **Pros and Cons of Buying a 2018-2021 Lincoln Navigator with a 3.5L EcoBoost Engine (ML3E-6C094-EA, Left Cylinder Head Camshafts Issue)**

#### **Pros**

1. **Strong Performance** The 3.5L EcoBoost V6 engine produces **300 horsepower and 370 lb-ft of torque**, delivering strong acceleration and towing capacity (up to **8,600 lbs** with the proper package). This makes it well-suited for heavy-duty tasks and highway driving.

2. **Luxury Brand & Comfort** As a Lincoln Navigator, the vehicle offers premium interior materials, advanced infotainment (SYNC 3 with touchscreen), adaptive cruise control, and available features like **massaging seats, head-up display, and wireless Apple CarPlay/Android Auto**. The ride quality is smooth, making it comfortable for long trips.

3. **Fuel Efficiency (Compared to V8 Models)** While not as efficient as a diesel or hybrid, the EcoBoost V6 provides **better MPG than a V8** (around **18-20 MPG highway** in standard trim vs. **14-16 MPG** for V8 models). This can save on fuel costs over time.

4. **Reliability of the EcoBoost Platform** Ford s 3.5L EcoBoost engines (used in F-150, Explorer, and Navigator) have generally been **more reliable than older V8 engines** in this segment. With proper maintenance, they can last **200,000 miles**.

5. **Available Tech & Safety Features**

- **Co-Pilot360 ** (standard in higher trims) includes blind-spot monitoring, rear cross-traffic alert, and automatic emergency braking.

- **Adaptive cruise control** and **lane-keeping assist** help with highway driving.

- **Available 360-degree camera** for parking ease.

6. **Resale Value** Lincolns hold their value better than many luxury brands, and the Navigator remains a **high-demand SUV**, which can help if you decide to sell later.

7. **Towing & Hauling Capability** With the **proper package (Max TOW)**, this vehicle can tow **up to 8,600 lbs**, making it ideal for boat owners, RVs, or heavy-duty work.

8. **AWD Option** The **AWD system** improves traction in snow and off-road conditions, though it s not as robust as a dedicated off-roader.

#### **Cons**

1. **Camshaft Issue (ML3E-6C094-EA Left Cylinder Head)**

- **Known Problem:** Some 2018-2021 Lincoln Navigators (and Ford Explorers/F-150s) with the **3.5L EcoBoost engine** have reported **camshaft wear or failure**, particularly on the **left cylinder head**. This can lead to:

- **Rough idling, misfires, or loss of power**

- **Check Engine Light (P0016, P0017, or P0021 codes)**

- **Potential for catastrophic engine failure if ignored**

- **Cost of Repair:** Replacing the camshafts or related components can range from **$1,500 to $3,500 **, depending on labor and parts.

- **Warranty Coverage:** If the vehicle is still under **Ford s 3-year/36,000-mile powertrain warranty**, this may be covered. After warranty expires, repairs become the buyer s responsibility.

2. **Higher Maintenance Costs Than Competitors**

- Luxury vehicles (especially Lincolns) tend to have **more expensive parts and labor** than mass-market SUVs (e.g., Chevy Tahoe, Ford Expedition).

- **EcoBoost engines require premium fuel** (91 octane) to avoid performance issues.

3. **Fuel Economy Not Great for a Large SUV**

- While better than a V8, the **3.5L EcoBoost still averages around 18-20 MPG highway**, which is **lower than diesel or hybrid alternatives** (e.g., Ram 1500 Diesel gets 25 MPG).

4. **Interior Quality Variability**

- Some owners report **cheap plastics or rattles** in lower trims, though higher trims (e.g., Black Label) have **premium leather and wood/aluminum accents**.

5. **Towing & Hauling Limitations Without Upgrades**

- The **standard Navigator may not have the Max TOW package**, which is needed for **full 8,600 lbs towing**. Adding this later can be expensive.

6. **Resale Depreciation**

- Luxury SUVs depreciate quickly. A 2018 Navigator may lose **30-40% of its value in 5 years**, though this is typical in the auto industry.

7. **Potential for Other Electrical Issues**

- Some owners report **infotainment glitches, sensor failures, or electrical gremlins** (e.g., window regulators, door locks).

8. **Competition from More Efficient Alternatives**

- If fuel economy is a priority, **diesel V8s (Ram 1500), hybrids (Toyota Sequoia), or even smaller turbocharged V6s (Chevy Tahoe 3.0L Turbo)** may be better choices.

---

### **Ending Conclusion**

The **2018-2021 Lincoln Navigator with a 3.5L EcoBoost engine** is a **powerful, luxurious, and capable SUV** that excels in **towing, comfort, and performance**. However, the **camshaft issue on the left cylinder head** is a **major red flag** that could lead to **expensive repairs** if not addressed. If the vehicle is **still under warranty**, this concern is mitigated. If not, the buyer must **budget for potential camshaft replacement** (likely **$1,500 $3,500**).

For buyers who **prioritize luxury, towing capacity, and don t mind higher maintenance costs**, this Navigator can be a **great choice** **if the camshaft issue is confirmed fixed or covered by warranty**. However, if **fuel efficiency, long-term reliability, or lower maintenance costs** are more important, alternatives like a **diesel Ram 1500, Toyota Sequoia Hybrid, or a well-maintained used V8 Navigator** may be better options.

---

### **Recommendation**

- **Get a pre-purchase inspection (PPI) focused on the camshafts and engine condition.**

- **Check if the vehicle is under warranty** if yes, the camshaft issue should be covered.

- **Consider a higher trim (e.g., Black Label) for better interior quality.**

- **Demand a full engine inspection** and **service records proving camshafts were replaced or serviced.**

- **Avoid vehicles with check engine lights or misfire codes** these are likely to have camshaft issues.

- **Budget for potential camshaft replacement** if the seller cannot provide proof of repairs.

- If **towing is the priority**, a **Ford F-150 Raptor (3.5L EcoBoost) or Ram 1500 Diesel** may offer better reliability.

- If **fuel efficiency matters**, a **Toyota Sequoia Hybrid or Chevy Tahoe 3.0L Turbo** could be more cost-effective long-term.

- If **luxury and comfort are key**, a **used 2020 Navigator with a V8 (if camshafts are confirmed good)** might be a safer bet.

- **Worth it if:** The camshaft issue is resolved, warranty is active, and you need a **luxury towing SUV**.

- **Not worth it if:** You re buying used without proof of camshaft repairs, or if you prefer **lower maintenance and better fuel economy**.
