### **Pros and Cons of Buying a Mercedes-Benz 247-817-00-16 (Star) Engine**

The **Mercedes-Benz 247.962-00-16 (M117) engine**, commonly referred to as the **"Star" engine**, was a popular inline-six powerplant used in various Mercedes-Benz models from the late 1970s to the early 1990s. Below is a detailed analysis of its advantages and disadvantages, followed by a conclusion and recommendation.

---

### **Pros of the Mercedes-Benz 247-817-00-16 Engine**

1. **Proven Reliability (When Maintained Properly)**

- The M117 engine was designed for durability and was widely used in Mercedes-Benz sedans, station wagons, and some commercial vehicles.

- Many examples with proper maintenance (regular oil changes, valve adjustments, and timing belt replacements) have lasted well over 200,000 miles.

2. **Strong Mid-Range Torque**

- The inline-six configuration provides smooth power delivery, making it well-suited for highway driving and towing (in compatible models).

- The naturally aspirated versions (especially the **2.8L and 3.0L variants**) offer adequate power for daily driving without excessive strain.

3. **Classic Mercedes-Benz Build Quality**

- The engine block and components were forged with precision, giving it a robust structure compared to some mass-produced engines of the era.

- The **piston-to-valve clearance** and **camshaft design** were refined over time, improving longevity in later models.

4. **Availability of Parts and Aftermarket Support**

- Being an older but still common engine, replacement parts (pistons, rods, bearings, gaskets) are relatively accessible, especially in Europe and North America.

- Aftermarket support includes remanufactured engines, performance upgrades (e.g., headers, fuel system modifications), and tuning options for those willing to invest.

5. **Lower Fuel Consumption Compared to Modern V8s (in Older Models)**

- In its heyday, the M117 was more fuel-efficient than many contemporary V8 engines, making it a practical choice for sedans like the **230/280/300E (W123)** and **240D/300D (diesel versions)**.

6. **Potential for Restoration and Classic Appeal**

- If you re interested in classic Mercedes-Benz vehicles, the M117 engine adds to the nostalgic and collectible value of models like the **1980s W123 or 1990s W124**.

- Restoring one can be a rewarding project for enthusiasts.

7. **Diesel Version (M117D) Efficiency**

- The **diesel variants (e.g., OM617)** were known for their fuel efficiency and torque, making them ideal for long-distance driving in older Mercedes like the **240D or 300D**.

---

### **Cons of the Mercedes-Benz 247-817-00-16 Engine**

1. **High Maintenance Requirements**

- The engine is **notoriously thirsty for oil** and requires **frequent oil changes** (every 3,000 5,000 miles in some cases, depending on conditions).

- **Valve adjustments** (every 30,000 40,000 miles) are critical to prevent excessive wear on the camshaft and lifters.

- **Timing belt and water pump replacement** should be done every **60,000 100,000 miles** to avoid catastrophic failure.

2. **Common Failure Points**

- **Rod bearings and main bearings** wear out over time, leading to **knocking or metal shavings in the oil**.

- **Piston rings** can leak, causing **blue smoke from the exhaust** and poor compression.

- **Head gasket failures** are possible, especially in high-mileage examples, leading to **coolant leaks, overheating, or white smoke**.

- **Fuel system issues** (carburetors in older models, later fuel-injected versions prone to sensor failures) can cause rough idling or stalling.

3. **Poor Fuel Economy in Modern Standards**

- Compared to modern turbocharged or hybrid engines, the M117 is **inefficient by today s standards**, especially in naturally aspirated versions.

- **Diesel models** are better but still lag behind modern diesel engines in efficiency and emissions compliance.

4. **Emissions and Modern Compliance Issues**

- Many **pre-1990 M117 engines** do not meet modern emissions standards, making them **illegal to drive in some regions** without extensive modifications (e.g., catalytic converter swaps, EGR deletions).

- **Smog checks** in states like California may require expensive retrofits.

5. **High Repair Costs**

- Labor costs for Mercedes-Benz mechanics can be **expensive**, especially for specialized work like **camshaft grinding or engine rebuilds**.

- **Remanufactured engines** are available but may not last as long as a properly maintained original.

6. **Rust and Corrosion in Older Models**

- Many M117 engines in older Mercedes (especially those from the 1970s early 1980s) suffer from **rust in the oil pan, rocker cover, and exhaust manifolds**.

- **Block rust** can weaken the engine, leading to **oil leaks or catastrophic failure**.

7. **Limited Power Output in Stock Form**

- The **naturally aspirated versions** (e.g., 2.8L, 3.0L) produce **around 120 160 horsepower**, which is adequate but not impressive by modern standards.

- **Turbocharged versions (e.g., 3.0L Turbo in the 300E 3.0)** are more powerful but prone to **turbo lag and reliability issues** if not maintained.

8. **Difficulty Finding Skilled Mechanics**

- While Mercedes-Benz dealerships still service these engines, **independent mechanics may lack experience** with the M117 s quirks, leading to misdiagnoses or improper repairs.

---

### **Conclusion**

The **Mercedes-Benz 247-817-00-16 (M117) engine** is a **characteristic but high-maintenance** powerplant that excels in **classic Mercedes-Benz vehicles** but requires **dedicated upkeep** to remain reliable. It is best suited for:

- **Enthusiasts who enjoy restoring and maintaining classic cars.**

- **Owners of older Mercedes (W123, W124, etc.) who prioritize driving experience over modern efficiency.**

- **Those willing to invest in regular maintenance (oil changes, valve adjustments, timing belt replacements).**

However, for **daily driving in modern conditions**, the M117 s **fuel inefficiency, emissions concerns, and high repair costs** make it a less practical choice compared to newer engines. If you re considering this engine, **a thorough inspection by a Mercedes specialist is essential** to assess its condition and potential longevity.

---

### **Recommendation**

- You are **passionate about classic Mercedes-Benz** and willing to **commit to maintenance**.

- The engine has **low miles (under 100,000) and a clean service history**.

- You plan to **restore or modify the vehicle** rather than use it as a daily driver.

- You can **afford potential repairs** (budget **$3,000 $6,000 ** for a rebuild if needed).

- You need **modern fuel efficiency, low emissions compliance, or minimal maintenance**.

- The engine has **high miles (over 200,000) without proof of proper maintenance**.

- You cannot **find a trusted Mercedes mechanic** to service it.

- You re looking for **reliable, long-term daily transportation** without extra effort.

**Final Verdict:** The M117 is a **great engine for the right owner** someone who appreciates classic cars and is prepared for the challenges. For most modern drivers, a **reliable modern engine (e.g., OM651 diesel, M276 gasoline, or a remanufactured M117 with a warranty)** would be a safer choice.
