### **Ford MB5Z-16720-B (16720-B) Nameplate Overview**
The **Ford MB5Z-16720-B** is a **16-valve, 2.0L inline-4 engine** (also known as the **Duratec HE**) produced by Ford from **2003 to 2010**. It was used in various models, including the **Ford Focus (2005 2010), Mazda3 (2004 2010), and Mercury Milan (2005 2007)**. Below is a detailed breakdown of its **pros, cons, and final recommendation**.
---
### **Pros of the Ford MB5Z-16720-B**
1. **Reliability and Durability**
- The **Duratec HE engine** is widely regarded as one of Ford s most reliable inline-4 engines, especially for its era.
- Many units last **200,000 miles** with proper maintenance, particularly if the **timing chain** (not belt) is serviced regularly.
- Fewer major issues compared to some of Ford s V6 engines from the same period.
2. **Good Power Output for Its Class**
- Produces **140 150 horsepower** (depending on model year and tuning), which was adequate for its time.
- Paired with a **5-speed manual or 4/5-speed automatic**, it provided a **balanced driving experience** without excessive strain.
- **Torque is smooth**, making it suitable for daily driving and light towing (up to 1,500 lbs with proper setup).
3. **Simpler Design Compared to Some Competitors**
- Unlike some modern turbocharged engines, the **naturally aspirated 16720-B** has **fewer high-stress components**, reducing long-term failure risks.
- **No forced induction** means fewer issues with turbo lag, wastegate failure, or intercooler leaks.
4. **Aftermarket Support & Tuning Potential**
- The engine responds well to **bolt-on modifications** (intake, exhaust, headers) and **ECU tuning**, allowing for **easy power gains** (20 50 HP with minimal risk).
- **Common mods** include:- **Cold air intake** (improves airflow)
- **Cat-back exhaust** (better sound and slight power increase)
- **ECU flash** (freezes ECU for better throttle response)
- **Upgraded fuel pump & injectors** (for forced induction builds)
- **Turbocharging is possible** (though requires careful tuning to avoid reliability issues).
5. **Affordable Parts & Maintenance**
- **Common wear items** (spark plugs, belts, filters) are **cheap and widely available**.
- **Timing chain service** (every 100,000 150,000 miles) is **less expensive** than a timing belt job on some competitors.
- **Common failures (if neglected)** are often **repairable without engine replacement**.
6. **Good for Beginners & DIY Enthusiasts**
- The engine is **not overly complex**, making it a **good learning platform** for those interested in **mechanical work**.
- **Common issues** (like oil leaks or valve cover gasket failure) are **relatively easy to fix**.
7. **Fuel Efficiency**
- In a **well-maintained manual transmission model**, it achieves **25 30 MPG highway**, which is **decent for a naturally aspirated 4-cylinder**.
- Better than many V6 engines of the same era in terms of **fuel economy**.

### **Cons of the Ford MB5Z-16720-B**
1. **Timing Chain & Guide Wear (If Neglected)**
- While **better than a timing belt**, the **timing chain and guides** can wear out over **150,000 miles** if not serviced.
- **Symptoms of failure**: **Rattling noise under acceleration**, misfires, or **chain jumping** (which can bend valves).
- **Preventative maintenance is crucial** replacing guides and tensioners at **100K 120K miles** extends longevity.
2. **Oil Leaks (Common but Fixable)**
- **Valve cover gasket** and **oil pan gasket** leaks are **not uncommon**, especially in older examples.
- **PCV valve failure** can cause **oil leaks around the valve cover**.
- **Fix is straightforward** (new gaskets torque specs), but **recurring leaks can be annoying**.
3. **Head Gasket & Cylinder Head Issues**
- **Head gasket failure** is a **known issue**, though **less common than in some other Ford engines** (e.g., 3.8L V6).
- **Symptoms**: **Coolant in oil, white smoke from exhaust, overheating, or compression loss**.
- **Prevention**: **Regular coolant flushes** and **checking for warped heads** (common in high-mileage examples).
- **Repair cost**: **$800 $1,500** (labor-intensive but doable).
4. **Water Pump Failure (Linked to Timing Chain Service)**
- The **water pump is chain-driven**, so it **must be replaced during timing chain service**.
- **Failure can lead to overheating**, so **always replace it at the same time**.
5. **Throttle Body & Idle Issues**
- **Carbon buildup in the throttle body** can cause **rough idling, stalling, or hesitation**.
- **Solution**: **Throttle body cleaning** (every 50K 70K miles) or replacement.
- **Modern ECUs may not adapt well** to heavily modified throttle bodies.
6. **Suspension & Drivetrain Wear (Model-Dependent)**
- The **Focus/Mazda3 platform** is **notoriously soft** in later years (2008 ), with **worn bushings, struts, and ball joints**.
- **Front subframe rust** is a **common issue** in **harsh climates** (especially in the U.S. Midwest/Northeast).
- **Rear differential leaks** (if equipped with a **limited-slip differential**) can be a **nuisance**.
7. **Electrical & Sensor Failures**
- **Oxygen sensors, MAF sensors, and crankshaft position sensors** can fail over time, leading to **check engine lights**.
- **Modern OBD-II scanners** make diagnosis easier, but **replacement parts are cheap**.
8. **Resale Value & Parts Availability**
- **Not a high-demand engine** for classic car enthusiasts, so **parts may be harder to find** than on a **Duramax or LS engine**.
- **Aftermarket support is strong**, but **OEM parts may become scarce** as models go out of production.
9. **Noise & Vibration (In Some Cases)**
- **Manual transmission models** can develop **clutch wear**, leading to **grinding or slipping**.
- **Automatic transmissions (5R55)** are **reliable but can develop solenoid issues** over time.
- **Exhaust note** is **not as aggressive** as some modern turbocharged engines, which may be a downside for some.
10. **Limited High-Performance Potential Without Mods**
- **Stock power is modest** (140 150 HP), so **serious performance builds require tuning and upgrades**.
- **Turbocharging is possible but risky** if not done correctly (can lead to **valve float, oil leaks, or head gasket failure**).
