Review AUDI 4.0l Engine Piston Connecting Rod Set Oem fits BENTLEY S8 GT 2013–2014

The **Audi 079107066EA engine piston and connecting rod set** for the **2013 2014 Bentley GT (4.0L V8)** represents a premium, high-performance replacement solution designed to restore peak mechanical efficiency and longevity to one of the most iconic luxury grand tourers ever produced. Engineered to exacting specifications, this aftermarket component set is meticulously crafted to match the original equipment manufacturer (OEM) tolerances of the **W12 (Type 4M) 4.0L twin-turbocharged V8** found in the Bentley GT, ensuring seamless integration with the aluminum cylinder block and forged-steel crankshaft assembly. Each piston in this set is forged from high-grade aluminum alloy, reinforced with precision-machined rings and a robust wrist pin design to withstand the extreme pressures and thermal cycling inherent in high-performance turbocharged applications. The connecting rods, forged from heat-treated steel, feature a robust I-beam construction for optimal strength-to-weight balance, minimizing reciprocating mass while maintaining rigidity to prevent bending or fatigue under the demanding loads of aggressive driving or extended high-RPM operation. This set is particularly well-suited for enthusiasts seeking to address wear in the original pistons or rods, whether due to normal wear-and-tear, high-mileage operation, or the aggressive power modifications often seen in Bentley GTs tuned for track use or high-speed cruising. The compatibility extends beyond standard applications, making it an ideal choice for owners who have upgraded to aftermarket turbochargers or forced induction systems, as the reinforced design can handle the increased cylinder pressures without compromising durability. Whether installed as part of a routine maintenance overhaul or a performance-focused rebuild, this piston and rod set delivers a blend of reliability, precision engineering, and the kind of refined power that defines the Bentley GT s legendary driving experience.

### **Pros and Cons of Buying a Bentley GT 4.0L Engine Piston & Connecting Rod Set (Part Number: Audi 079107066EA, Fits 2013-2014 Models)**

1. **High Performance & Reliability** The 4.0L twin-turbocharged V8 in the Bentley GT (shared with the Audi S6/S8 and Porsche Panamera) is a robust engine when properly maintained. A fresh piston and connecting rod set can restore peak performance, improve power delivery, and extend engine life if the original components were worn or damaged.

2. **OEM Quality** Audi s part number (079107066EA) indicates an original equipment (OEM) or high-quality aftermarket component designed to match factory specifications. This ensures proper fitment, durability, and compatibility with the engine s internal mechanics.

3. **Prevents Catastrophic Failure** If the engine has signs of wear (knocking, oil consumption, or compression loss), replacing pistons and connecting rods can prevent a seized engine or rod knock a failure that often leads to extensive (and expensive) damage.

4. **Potential for Increased Longevity** If the engine was previously neglected or had excessive wear, a rebuild with new pistons and rods can restore structural integrity, reducing the risk of future issues.

5. **Market Availability & Support** Audi and Bentley parts are widely available through dealerships, specialty performance shops, and reputable aftermarket suppliers. This ensures ease of installation and access to technical support.

6. **Potential for Enhanced Power (If Tuned)** A rebuilt engine with fresh internals can better handle forced induction (turbo upgrades) or tuning, allowing for increased power output if desired.

---

1. **High Cost** Piston and connecting rod sets for a high-performance engine like the 4.0L V8 are expensive. The labor cost for installation (especially in a Bentley/Audi shop) can be substantial, often ranging from **$3,000 to $6,000 ** depending on the shop and location.

2. **Complex Installation** This is not a simple DIY job. The engine must be fully disassembled, inspected, and reassembled with precision. Improper installation can lead to premature failure or damage to other components.

3. **Potential for Hidden Issues** If the engine has other underlying problems (worn bearings, cracked blocks, or turbo damage), replacing just the pistons and rods may not fully resolve the issue. A full engine rebuild may be necessary, increasing costs.

4. **Warranty & Depreciation Concerns** Bentley and Audi engines are known for longevity, but if the vehicle has high mileage or was previously abused, the return on investment may be limited. A rebuilt engine won t restore the car s value as much as a well-maintained original one.

5. **Time-Consuming Process** A full rebuild can take **100 hours** of labor, requiring the car to be off the road for an extended period.

6. **Alternative Solutions May Exist** If the engine is only experiencing minor issues (e.g., oil consumption), less invasive fixes (e.g., valve seals, oil control rings, or turbo upgrades) might be more cost-effective than a full piston/rod replacement.

Replacing the pistons and connecting rods in a **2013-2014 Bentley GT 4.0L engine** is a **major but justified investment** if the engine is showing signs of severe wear, knocking, or compression loss. It can **restore performance, prevent catastrophic failure, and extend the engine s life** especially if the vehicle is a high-mileage or performance-oriented model.

However, the **high cost and complexity** mean this should only be done when absolutely necessary. If the engine is still running reliably with minor issues, exploring **less invasive repairs** (e.g., turbo upgrades, oil control fixes) may be more practical.

- **If the engine is failing (knocking, oil burning, low compression):** Proceed with the rebuild, but **get multiple quotes** from reputable shops (both OEM and specialty performance garages) to ensure competitive pricing.

- **If the engine is still running but showing signs of wear (e.g., increased oil consumption):** Consider **diagnostic testing** (compression test, leak-down test) before committing to a full rebuild. A **turbo upgrade or valve job** might be sufficient.

- **If the car is a daily driver with high mileage:** Weigh the **cost vs. remaining value** a rebuilt engine may not significantly improve resale, but it could save you from a **far more expensive failure** down the line.

- **If you re not experienced with engine rebuilds:** **Do not attempt this as a DIY project.** Hire a **specialized Bentley/Audi performance shop** with experience in twin-turbo V8 engines.

**Final Verdict:** This is a **legitimate upgrade for troubled engines**, but it should be approached with careful consideration of costs, alternatives, and long-term engine health. If done correctly, it can **save you from a complete engine replacement** which would be far more expensive.
