Review CHRYSLER 06-10 Dodge Charger Conv Sed 3.5l Right Cylinder Head Oem fits SEBRING 2008–2010

The **Chrysler 4663892 OEM cylinder head (3.5L V6, Right Side) for the 2006 2010 Dodge Charger and 2008 2010 Chrysler Sebring sedan** represents a critical and high-performance component in the engine bay of these iconic American muscle cars. Engineered to exacting specifications by Chrysler s original equipment manufacturing (OEM) division, this cylinder head is designed to deliver optimal combustion efficiency, durability, and power output for the **3.5L Pentastar V6** engine, which powers both the Charger s sporty sedan and coupe body styles as well as the Sebring s refined yet capable performance. Crafted from high-grade cast aluminum with precision-machined passages, this right-side head features a **four-valve-per-cylinder design**, incorporating advanced intake and exhaust ports that enhance airflow and torque delivery, particularly noticeable in the Charger s aggressive 0-60 mph acceleration and the Sebring s responsive handling. The head is equipped with **hydraulic valve lifters** and **titanium nitride-coated valves**, ensuring smooth operation, reduced friction, and extended longevity under high-performance driving conditions. Additionally, it integrates a **high-flow intake manifold** and **dual exhaust ports**, contributing to the engine s balanced power band and smooth idle, a hallmark of the Pentastar s refined yet spirited performance. Whether you re restoring a classic Charger to its original glory or upgrading an existing engine build, this OEM cylinder head guarantees a seamless fit, superior cooling efficiency, and the reliability expected from Chrysler s legacy of American engineering. Its compatibility with the **3.5L V6 s fuel injection system** and **variable valve timing (VVT)** further underscores its role in maintaining peak performance and fuel economy, making it an indispensable part for enthusiasts and mechanics alike seeking authenticity and performance in their vehicles.

### **Pros and Cons of Buying a 2006 2010 Dodge Charger (3.5L V6) or 2008 2010 Chrysler Sebring (3.5L V6) with a Right Cylinder Head Issue (Part # 4663892)**

#### **Pros**

1. **Reliable Base Engine** The 3.5L Pentastar (or earlier 3.5L V6 in pre-2011 models) is a solid powerplant when maintained properly. It s known for good fuel economy (around 18 22 MPG combined) and decent power (243 280 HP depending on the year and trim).

2. **Proven Durability** Many of these vehicles, especially when properly serviced, last well beyond 200,000 miles. The 3.5L V6 is less prone to catastrophic failure compared to some other engines of its era.

3. **Strong Aftermarket Support** Parts, modifications, and tuning are widely available. Performance upgrades (intake, exhaust, ECU tuning) can significantly improve power and drivability.

4. **Good Handling & Ride** The Charger and Sebring (especially the SXT, R/T, or SRT8 variants) offer a sporty, engaging driving experience. The suspension is well-tuned for a muscle car, and the 3.5L V6 provides smooth power delivery.

5. **Affordable to Own** Fuel efficiency is better than many V8 muscle cars, and parts are relatively inexpensive compared to luxury or high-performance vehicles. Insurance and maintenance costs are moderate.

6. **Potential for Modification** If you enjoy tinkering, these platforms are great for forced induction (turbocharging) or nitrous upgrades. The 3.5L can handle modifications well with proper cooling and support.

7. **Resale Value (for Well-Maintained Examples)** While not as strong as a modern muscle car, a clean, low-mileage example with service records can still hold value, especially if it s a sought-after trim (e.g., SRT8, Limited, or high-mileage examples with no major issues).

8. **Spacious & Practical** The Charger and Sebring offer decent interior space, making them more practical than some competitors like the Camaro or Mustang.

#### **Cons**

1. **Right Cylinder Head Issue (Part # 4663892)** The most critical concern is the **faulty right cylinder head** (part # 4663892) found in these engines. Symptoms include:

- **Oil leaks** (common around the valve cover gasket or oil filter housing)

- **Misfires, rough idle, or loss of power** (due to oil starvation or valve train issues)

- **Excessive oil consumption** (burning oil, leading to blue smoke from the exhaust)

- **Valvetronic actuator failure** (in some cases, causing hesitation or stalling)

- **Head gasket leaks** (less common but possible if the head is warped or improperly seated)

**This is a known chronic issue** that often requires **replacing the right cylinder head** (or at least the valve cover gasket, oil filter housing, and related components). The cost of repair can range from **$1,500 $3,500 **, depending on labor rates and whether the head needs machining or replacement.

2. **Transmission Problems (Especially in Early Models)** Some 2006 2008 Chargers and Sebrings came with **5-speed automatics (545RFE)** that are prone to:

- **Slipping or delayed shifting**

- **Torque converter failure**

- **Solenoid issues**

Upgrading to a **6-speed (62TE)** or **6-speed automatic (62TE/62TEF)** can improve reliability but adds cost.

3. **Electrical & Sensor Failures** These vehicles are notorious for **faulty sensors** (MAF, crankshaft, camshaft, oxygen sensors) and **electrical gremlins** (bad wiring harnesses, faulty relays). Frequent **check engine light (CEL) codes** can be frustrating.

4. **Rust & Body Issues** Many examples (especially in snowy or coastal regions) suffer from **frame rust, wheel well corrosion, and undercarriage rot**. A thorough inspection is **mandatory** before purchase.

5. **Recalls & Unresolved Issues** Some models had **unfixed recalls** (e.g., airbag, seatbelt, or fuel system issues). Always check **NHTSA s recall database** before buying.

6. **Depreciation** These vehicles have **declined significantly in value** over the years. Even well-maintained examples are not considered "collectible" like some muscle cars.

7. **Parts & Labor Costs** While parts are affordable, **labor rates** (especially for head work) can be high. Some mechanics specializing in Chrysler/Dodge work may charge premium rates.

8. **Potential for Hidden Damage** The **right cylinder head issue** is well-documented, but other problems (e.g., **timing chain stretch, water pump failure, or exhaust manifold leaks**) can pop up unexpectedly.

### **Ending Conclusion & Recommendation**

#### **Should You Buy One?**

**You find a well-documented, low-mileage example** (under 100,000 miles) with **full service records**.

**The right cylinder head has already been addressed** (or you re prepared to budget **$1,500 $3,500** for repairs).

**You re okay with potential electrical/sensor issues** (and willing to troubleshoot them).

**You plan to modify it** (since these cars respond well to upgrades).

**You don t mind occasional maintenance** (oil changes, sensor replacements, etc.).

**You can t afford the right cylinder head repair** (this is the #1 killer of these engines).

**The seller won t provide a full service history** (especially for oil changes and head work).

**The car has rust, transmission issues, or a check engine light with unresolved codes**.

**You want a "set-and-forget" vehicle** (these require more attention than a modern sedan).

#### **Best Approach If You Still Want One**

1. **Get a Pre-Purchase Inspection (PPI)** Have a **trusted mechanic** (preferably one familiar with Chrysler/Dodge) thoroughly inspect the engine, transmission, and electrical system.

2. **Verify the Right Cylinder Head**

- Check for **oil leaks** (especially around the valve cover and oil filter housing).

- Listen for **misfires or rough idle** (indicating oil starvation).

- Confirm if the **head has been replaced or machined** (ask for proof).

3. **Test Drive & Monitor for Issues**

- Watch for **hesitation, stalling, or poor acceleration** (signs of valvetronic or oil flow problems).

- Check for **blue smoke from the exhaust** (burning oil).

4. **Budget for Upgrades**

- If buying used, consider **upgrading the transmission** (6-speed is more reliable).

- Replace **worn sensors, belts, and hoses** before long-term ownership.

5. **Consider a Lower-Mileage Example** A **2008 2010 model with under 80,000 miles** is preferable over a high-mileage 2006.

#### **Final Recommendation**

If you re **mechanically inclined, willing to invest in repairs, and don t mind occasional issues**, a **well-maintained 2008 2010 Charger or Sebring with a 3.5L V6** can be a **fun, affordable, and mod-friendly** purchase. However, **the right cylinder head repair is non-negotiable** if the seller won t confirm it s been done, **walk away**.

For **casual drivers or those seeking a hassle-free vehicle**, a **modern muscle car (Camaro, Mustang, Challenger, or even a used SRT8)** would be a **safer and more reliable** choice.

**Best Case:** Buy a **low-mileage example with proof of head work**, budget for **transmission upgrades and sensors**, and enjoy a **great daily driver or project car**.

**Worst Case:** Buy a **high-mileage, neglected example without head repairs**, and face **unexpected $3,000 repairs** within a few years.

**Verdict:** **Proceed with caution, thorough inspection, and a clear repair plan.**
