Review RENAULT Medallion Cylinder Head fits 1988–1989

The **Renault 306 (58249) Medallion cylinder head** from the **1988 1989 model years** represents a finely engineered component designed to deliver reliable performance and durability for the iconic **F2R (1.6L 16-valve) engine** found in the Renault 306. This precision-crafted head is forged from high-quality **cast iron**, ensuring robust structural integrity while maintaining optimal heat dissipation to prevent overheating during high-performance driving. The **16-valve design** features two overhead camshafts (DOHC), each driven by a **timing belt**, allowing for efficient airflow and improved combustion efficiency critical for the Medallion s sport-tuned character. The **intake and exhaust ports** are meticulously machined to maximize volumetric efficiency, ensuring a smooth and responsive throttle response, whether cruising on highways or navigating tight corners. The **valve guide and seat inserts** are precision-engineered to minimize wear, extending the head s lifespan even under demanding conditions, while the **spark plug bores** are strategically positioned for optimal ignition distribution. This cylinder head is a key element in the **Medallion s reputation for performance**, offering a balance between power delivery and reliability that enthusiasts and mechanics alike appreciate. Whether restoring a classic Renault 306 or upgrading an existing engine, this **OEM-quality head** ensures a seamless fit and the performance-driven spirit that defines the Medallion s legacy.

### Pros and Cons of Buying a Renault 306 (58249 Engine, 1988-1989) Medallion Cylinder Head

The Renault 306 with the 58249 engine (a 1.6L or 1.8L variant, depending on the model) from the late 1980s, particularly with the Medallion cylinder head, has several strengths that may appeal to certain buyers:

1. **Reliability and Simplicity** The 58249 engine is a robust, straightforward design with fewer electronic complexities compared to later models. Many of these engines are known for lasting well with basic maintenance, especially if they have been properly serviced.

2. **Affordability** Parts for this engine are relatively inexpensive compared to modern vehicles. A full rebuild kit, gaskets, or even a used cylinder head can be found at a fraction of the cost of newer car components.

3. **Modding Potential** The 58249 engine is a popular choice among tuners. Upgrades such as turbocharging, porting the Medallion head, or swapping in a more efficient fuel system are well-documented and achievable with relatively accessible parts.

4. **Classic Appeal** The Renault 306, especially in its early years, has a cult following among enthusiasts who appreciate its retro styling and driving dynamics. Restoring one can be a rewarding project for those who enjoy working on older European cars.

5. **Fuel Efficiency (Stock)** In its stock form, the 1.6L version is reasonably efficient, making it practical for daily use if the car is well-maintained. The 1.8L variant offers slightly more power but at the cost of slightly reduced economy.

6. **Mechanical Durability** The Medallion head (a later evolution of the original head design) is more refined than earlier versions, with improved valve geometry and better sealing. This reduces the risk of oil consumption or valve issues compared to some earlier Renault heads.

7. **Community Support** There is a dedicated community of Renault 306 owners and tuners who share knowledge, parts, and modifications. This makes troubleshooting and finding help easier than for more obscure vehicles.

1. **Common Reliability Issues**

- **Timing Chain and Tensioner Problems**: The 58249 engine is notorious for timing chain stretch and tensioner failure, which can lead to catastrophic engine damage if not addressed. Regular inspection and replacement of the tensioner and guides are essential.

- **Oil Leaks**: The Medallion head, while an improvement, still suffers from oil leaks around the valve cover gasket, rear main seal, and oil filter housing gasket. These leaks are often a nuisance and can lead to oil starvation if ignored.

- **Water Pump Failures**: The water pump on these engines tends to fail prematurely, often leading to overheating. Replacing it is a straightforward job, but it s a recurring expense.

- **Fuel System Issues**: The original fuel injection system (especially on the 1.6L) can be finicky, with problems like clogged injectors, faulty sensors, or electrical gremlins. Upgrading to a more reliable system (e.g., a standalone ECU or mechanical fuel injection) is often recommended for reliability.

2. **Electrical Quirks** The 306 s electrical system, particularly in the 1988-1989 models, can be unreliable. Issues with the alternator, starter, or wiring loom are common, and repairs can be time-consuming without proper diagnostics.

3. **Maintenance Requirements** Unlike modern cars with oil change reminders and diagnostic trouble codes, the 306 requires diligent owner maintenance. Regular checks for leaks, belt tension, and fluid levels are necessary to prevent major failures.

4. **Driving Experience** While the 306 is fun to drive, it lacks modern comforts such as power steering, advanced safety features, and refined suspension tuning. The ride can be stiff, and the interior is basic by today s standards.

5. **Parts Availability** While parts are cheaper than on newer cars, some components (especially for the Medallion head) may be harder to find than on more common European cars. Stocking up on critical parts (e.g., timing chain kits, water pumps) is advisable.

6. **Emissions and Legal Compliance** In many regions, older cars like the 306 may struggle to meet modern emissions standards. Retrofitting catalytic converters or upgrading the fuel system to comply with local regulations can be costly and complex.

7. **Resale Value** The Renault 306, even in good condition, does not hold its value well. It is primarily valued by enthusiasts, so resale potential is limited unless you are selling to a dedicated collector.

8. **Build Quality** The 306 s body is prone to rust, especially in the wheel arches, sills, and rear quarter panels. A thorough inspection of the chassis and undercarriage is essential before purchasing to avoid costly corrosion repairs.

The Renault 306 with the 58249 engine and Medallion cylinder head is a vehicle that offers a blend of reliability, modding potential, and classic charm but only if the buyer is prepared for its quirks and maintenance demands. It is best suited for:

- **Enthusiasts** who enjoy working on mechanical projects and appreciate the driving experience.

- **Budget-conscious buyers** who prioritize affordability and are willing to invest time in upkeep.

- **Tuners** who see the engine as a platform for modifications rather than a plug-and-play solution.

For those seeking a hassle-free, modern daily driver or a car with high resale value, the 306 is not the best choice. However, for the right owner, it can be a rewarding and enjoyable project car.

---

1. **Thorough Inspection** Have a trusted mechanic or Renault specialist perform a pre-purchase inspection. Focus on the timing chain, water pump, oil leaks, and overall engine condition. Check for signs of past neglect, such as burnt oil or coolant leaks.

2. **Documentation and History** Request a full service history, especially for the engine and transmission. A well-documented car with regular maintenance is far more reliable.

3. **Budget for Repairs** Allocate funds for common issues like the timing chain, water pump, and oil leaks. Consider a full rebuild if the engine has significant wear or if the previous owner has not maintained it properly.

4. **Modifications vs. Stock** Decide whether you want to keep the car stock or modify it. If tuning is your goal, research the best upgrades (e.g., turbocharging, porting the Medallion head) and factor in their costs.

5. **Storage and Maintenance Plan** Ensure you have a plan for storing the car (e.g., in a garage) and for regular maintenance. Neglect is the fastest way to turn a reliable 306 into a money pit.

6. **Join the Community** Connect with Renault 306 forums or local clubs. They can provide valuable advice, part recommendations, and support for troubleshooting.

If you are willing to put in the effort and budget for maintenance, the Renault 306 with the 58249 engine can be a fantastic project car. However, if you prefer a low-maintenance vehicle or lack the time/inclination for repairs, it may not be the right choice.
