### **Pros and Cons of Buying a PACCAR Engine (L676018 / L67-6018 Hood) in Kenworth T680/T880, W990, Peterbilt 567/579**

PACCAR s **L676018 (6.7L Turbocharged Diesel)** is a robust engine commonly found in Kenworth T680/T880, W990, and Peterbilt 567/579 models. Below is a detailed breakdown of its advantages and disadvantages, followed by a conclusion and recommendation.

---

### **Pros of the PACCAR L676018 Engine**

1. **Proven Reliability**

- The L67 series has a long history of durability, particularly in heavy-duty trucking applications. Many operators report minimal issues if properly maintained.

- Known for its **low failure rates** compared to some competitors, especially in long-haul and regional fleets.

2. **High Torque Output**

- The **6.7L inline-six** produces strong torque (around **1,500 1,800 lb-ft**), making it well-suited for **heavy loads, grading, and towing**.

- Particularly effective in **Kenworth T880 (heavy-haul) and W990 (off-road/construction)** applications.

3. **Fuel Efficiency (Compared to V8s)**

- While not as fuel-efficient as modern **6.7L inline-sixes with newer tech**, it still offers **better MPG than a V8** in similar trucks.

- Older models (pre-2010) may have **lower efficiency** than newer PACCAR MX engines, but they remain competitive for their class.

4. **Simpler Design, Easier Maintenance**

- The **inline-six configuration** is generally **simpler and more cost-effective to repair** than a V8, with fewer moving parts.

- **Common rail direct injection** (in later models) improves fuel economy and reduces emissions compared to older mechanical injectors.

5. **Strong Aftermarket Support**

- Widely used in **Kenworth and Peterbilt models**, so **parts and mechanics are readily available**.

- **Remanufactured engines** are common and often cost-effective for fleet operators.

6. **Good for Heavy-Duty Work**

- The **T680 (with L67) is a popular choice for construction, logging, and over-the-road hauling** due to its **torque and durability**.

- The **W990 (off-road/grading)** benefits from its **ruggedness** in harsh conditions.

7. **Lower Initial Cost (vs. V8 or Newer Engines)**

- Compared to **PACCAR MX engines or Cummins X15**, the L67 is **less expensive upfront**, making it attractive for budget-conscious buyers.

---

### **Cons of the PACCAR L676018 Engine**

1. **Aging Technology (Compared to Modern Engines)**

- **No EGR (Exhaust Gas Recirculation) or SCR (Selective Catalytic Reduction) in older models**, leading to **higher emissions compliance risks** in newer regulations.

- **Later models (2010 ) added EGR and DPF**, but older ones may struggle with **2017 emissions standards** without modifications.

2. **Lower Fuel Efficiency Than Newer Engines**

- **Older L67 models (pre-2010) have worse MPG** compared to **PACCAR MX-13, Cummins X15, or Detroit DD15**.

- **Newer L67s (post-2010) improved efficiency**, but still **lag behind modern turbocharged diesels**.

3. **Higher Maintenance Costs Over Time**

- **Turbocharger failures** (especially in high-mileage units).

- **Injector wear** (older mechanical injectors degrade faster than modern common rail).

- **Rod bearing and piston ring wear** in high-mileage engines.

- **Remanufacturing costs can add up** if not properly maintained.

4. **Noise and Vibration (Inline-Six Character)**

- The **inline-six design is louder and more vibration-prone** than a V8, which some drivers find less comfortable.

- **Sound levels can be higher** than smoother-running modern engines.

5. **Limited Longevity Compared to V8s**

- While durable, **inline-sixes generally have shorter lifespans** than **V8s (e.g., Cummins X15, Detroit DD15)** in extreme conditions.

- **Rod bearing failures** can occur if oil changes are neglected.

6. **Resale Value Depreciation**

- **Older L67 engines (pre-2010) hold value poorly** compared to newer PACCAR or Cummins engines.

- **2010 2015 models** still have decent resale, but **2016 with EGR/DPF** are more desirable.

7. **Emissions Compliance Challenges**

- **Pre-2010 models may not meet 2017 EPA standards** without **EGR, DPF, or SCR retrofits**, adding cost.

- **Later L67s (2010 ) have EGR and DPF**, but **DPF regeneration issues** can still arise.

**Lower initial cost** compared to V8 or newer inline-six engines.

**Simplicity in maintenance** (easier to repair than a V8).

**Fleet owners needing maximum fuel efficiency** (modern MX-13 or X15 would be better).

**Operators in strict emissions zones** (pre-2010 models may require retrofits).

**Those seeking long-term low-maintenance reliability** (V8s like Cummins X15 last longer in extreme conditions).

- **Kenworth T680 (heavy-haul, construction)**

- **Peterbilt 567/579 (regional hauling, mixed duty)**

- **W990 (off-road, grading, where torque > MPG)**

- You need **modern emissions compliance** without retrofits.

- You want **the best fuel economy** in a long-haul truck.

- You re running **extreme duty cycles** (e.g., high RPM, constant heavy loads).

---

### **Final Recommendation**

- You re looking for a **torque-heavy, durable engine** in a **Kenworth T680/T880 or Peterbilt 567/579**.

- You **prioritize cost efficiency** over fuel economy.

- You **maintain it religiously** (oil changes, turbo monitoring, injector care).

- The truck is **under 200,000 miles** (or has a **full rebuild history**).

- You need **better fuel efficiency** **PACCAR MX-13 or Cummins X15**.

- You re in **strict emissions zones** **2010 L67 with EGR/DPF or a newer engine**.

- You want **longer engine life** **Cummins X15 or Detroit DD15**.

- **2010 2015 Kenworth T680/Peterbilt 567 with L67** (balance of torque, reliability, and cost).

- **Avoid pre-2010 models** unless you re prepared for **emissions retrofits and higher maintenance**.

- **Change oil every 5,000 7,500 miles** (or as per PACCAR s guidelines).

- **Monitor turbocharger health** (common failure point).

- **Consider a remanufactured L67** if buying used to extend lifespan.
