Review BMW Bush New Oem

The **BMW 46-71-7-660-074** is a high-performance, precision-engineered **valve cover** designed exclusively for BMW engines, specifically tailored to fit a range of inline-six (M60, M50, M52, and M54) and V8 (M62, M67, and M70) applications within the 1990s to early 2000s model lineup. Crafted from **high-grade aluminum alloy (typically A390 or A356)**, this valve cover is not only lightweight but also engineered to withstand the extreme thermal and mechanical stresses of high-performance driving, ensuring optimal heat dissipation while maintaining structural integrity. The cover features a **smooth, polished finish** on the exterior, contributing to both an aesthetic appeal and a reduction in aerodynamic drag, a detail that reflects BMW s commitment to both performance and design. Internally, the cover is meticulously machined to accommodate the engine s **camshafts, rocker arms, and valve springs**, with precise gasket surfaces that guarantee a secure, leak-proof seal when paired with the correct **EPDM or silicone gasket**. The **ventilation system** integrated into the design helps regulate oil vapor, preventing pressure buildup and ensuring long-term engine health, particularly in high-revving or turbocharged applications. Whether installed on a **BMW E36 330i, E38 540i, E39 540i, or E36 M3**, this valve cover is a critical component for maintaining peak engine performance, reliability, and longevity, embodying BMW s legacy of engineering excellence.

### **Pros and Cons of Buying a BMW 4 Series (E60/E61) F60/F61/F62/F63 (2006 2016) with VIN Range 46-71-71-660-074**

The **BMW 4 Series (E60/E61)** and its successor, the **F60/F61/F62/F63 (New 4 Series, 2013 2016)**, are iconic German sedans and coupes known for performance, luxury, and driving dynamics. The **VIN range 46-71-71-660-074** corresponds to a **2013 2014 BMW 4 Series Gran Coupe (F62/F63)** with a **3.0L twin-turbo inline-6 (N63B30T0)** engine, likely paired with an **8-speed ZF automatic transmission**. Below is a detailed breakdown of its strengths and weaknesses, followed by a conclusion and recommendation.

---

### **Pros**

1. **Strong Engine Performance**

- The **N63B30T0** is one of BMW s most capable inline-6 engines, producing **382 400 hp** (depending on tuning) and **369 lb-ft of torque**. It delivers strong low-end power and a linear powerband, making it ideal for spirited driving.

- Twin-turbocharging ensures good throttle response, though some models may suffer from turbo lag at very low RPMs.

- The engine is **durable** if maintained properly, with many reaching **150,000 miles** with basic upkeep.

2. **Premium Interior & Build Quality**

- The **F62/F63** generation features a **high-quality interior** with soft-touch materials, premium leather, and well-placed controls.

- **Comfortable seating** with good lateral support, though rear legroom is limited (typical for a 4 Series).

- **Advanced infotainment** (depending on trim) with **iDrive 5.0** (F62/F63), which supports **Bluetooth, USB, and navigation** (if equipped).

- **Heated/ventilated seats** and **adjustable pedals** are common on higher trims.

3. **Driving Dynamics & Handling**

- The **4 Series Gran Coupe** retains the **sporty rear-wheel-drive (RWD) or all-wheel-drive (xDrive) platform** of the coupe, offering **sharp steering, precise suspension tuning, and engaging rear-wheel bias**.

- **Adaptive suspension** (on higher trims) improves comfort without sacrificing sportiness.

- **Braking is strong** (Brembo calipers on performance models), though some owners report **brake fade** under heavy use.

4. **Luxury & Comfort Features**

- **Quiet cabin** (better than earlier E60 models) with **sound insulation**.

- **Heated steering wheel, ambient lighting, and climate control** on premium trims.

- **Comfortable ride** (especially in **Comfort mode**) for daily driving, though it s not as plush as a 5 Series.

5. **Reliability & Longevity (With Proper Maintenance)**

- The **N63 engine** is **more reliable than earlier BMW inline-6s** (e.g., M54, M57) but still requires **regular oil changes (every 5,000 7,500 miles)** to prevent sludge buildup.

- **Transmission (8-speed ZF)** is **smooth and durable**, though some early models had **software glitches** that were later fixed.

- **No major structural issues** reported in this VIN range, though **rust** (especially in snow-belt regions) should be inspected.

6. **Resale Value & Prestige**

- The **4 Series Gran Coupe** holds its value better than many competitors due to BMW s brand prestige.

- **Limited production** (especially in certain trims) makes it a **desirable collector s item** in the future.

7. **Aftermarket & Tuning Potential**

- The **N63 engine** is **highly tunable**, with options ranging from **stage 1 (380 400 hp)** to **stage 2 (500 hp)** with supporting mods (intercooler, exhaust, ECU flash).

- **Performance parts** (e.g., **M-Sport suspension, carbon fiber parts**) are widely available.

- **Track readiness** with optional **M Performance Package** (stiffer suspension, sport exhaust, etc.).

---

### **Cons**

1. **Higher Maintenance Costs**

- BMWs are **notoriously expensive to maintain**, with **premium parts, labor, and specialized service** required.

- **Oil changes, timing belt (if applicable), and turbo upgrades** can add up quickly.

- **Common issues** include:

- **Oil consumption** (some N63 engines burn oil, requiring frequent checks).

- **Water pump failure** (can lead to **engine overheating** if not addressed).

- **Transmission fluid changes** (should be done every **60,000 miles** to prevent wear).

2. **Turbocharger & Engine Reliability Concerns**

- The **N63 s twin-turbo setup** is **more complex than naturally aspirated engines**, leading to:

- **Turbo lag** (though less noticeable in later models).

- **Potential for turbo failure** if oil changes are neglected.

- **Carbon buildup in intake valves** (common in turbocharged engines, requiring **valve cleaning every 60,000 80,000 miles**).

- **Rod bearing wear** has been reported in some high-mileage examples, though this is **rare if maintained properly**.

3. **Infotainment & Tech Limitations**

- **iDrive 5.0 (F62/F63)** is **clunky and slow** compared to modern systems (e.g., **iDrive 7/8**).

- **No Apple CarPlay/Android Auto** (unless aftermarket solutions are installed).

- **Bluetooth connectivity issues** reported in some models.

- **Navigation (if equipped)** can be **slow to load** and lacks modern features.

4. **Fuel Economy & Running Costs**

- **Poor MPG for a luxury car** ( 18 22 MPG combined in automatic mode).

- **High fuel consumption** (especially in city driving) due to **turbo lag and heavy weight**.

- **Insurance costs** are **higher than average** due to performance and luxury status.

5. **Comfort & Practicality Trade-offs**

- **Limited rear legroom** (not ideal for tall passengers or families).

- **Rear seats are narrow and less comfortable** than in a 5 Series.

- **Luggage space is decent but not exceptional** ( 12 15 cu. ft. behind rear seats).

- **Noisy cabin at highway speeds** (wind and road noise are more noticeable than in later models).

6. **Electrical Gremlins**

- BMWs of this era are **prone to electrical issues**, such as:

- **Faulty sensors** (e.g., **mass airflow sensor, camshaft position sensor**).

- **Intermittent iDrive freezes or crashes**.

- **Power window/door lock malfunctions**.

- **Diagnosing and fixing these issues** can be **time-consuming and costly**.

7. **Depreciation & Market Saturation**

- While the **4 Series Gran Coupe holds value better than most**, it is **not as sought-after as a 5 Series or M car**.

- **High mileage examples (over 100,000 miles)** may have **higher maintenance risks** and **lower resale value**.

- **Competitors (Audi A5, Mercedes CLS, Lexus GS)** offer **similar luxury and performance at lower costs**.

8. **Potential Rust Issues**

- **Snow-belt regions** (e.g., Midwest, Northeast U.S.) may have **rust in wheel wells, rocker panels, and undercarriage**.

- **Always inspect for rust** before purchasing, as repairs can be **expensive**.

---

### **Conclusion**

The **BMW 4 Series Gran Coupe (F62/F63, 2013 2014) with a N63 engine** is a **fantastic choice for enthusiasts** who prioritize **performance, driving dynamics, and luxury** but are willing to **budget for maintenance**. It offers **strong power delivery, a refined interior, and engaging handling**, making it ideal for **daily driving and track use**.

However, **potential buyers should be prepared for**:

- **Higher upkeep costs** (oil changes, turbo maintenance, electrical issues).

- **Compromises in comfort and practicality** (rear space, fuel economy).

- **Outdated tech** (iDrive 5.0, no CarPlay/Android Auto).

If you **love BMWs, enjoy tuning, and don t mind the maintenance**,
