Review PORSCHE 2.7l Left 4-6 Engine Cylinder Head Good Cams fits BOXSTER CAYMAN 2006–2008

The **Porsche 987.1 Boxster and Cayman (997.20) 2.7L Flat-6 Engine Cylinder Head Cams** represent a meticulously engineered component designed for enthusiasts seeking to unlock the full potential of their 2006 2008 Porsche 911 Carrera, Boxster, or Cayman with the naturally aspirated 2.7-liter (M97.20) engine. This high-performance cylinder head camshaft set is crafted to refine the already legendary breathing characteristics of Porsche s iconic flat-six architecture, delivering a noticeable improvement in throttle response, mid-range torque, and overall engine efficiency. The M97.20 engine, known for its robust construction and precision machining, benefits significantly from upgraded cams that optimize valve timing enhancing both the intake and exhaust phases to promote better airflow and combustion. These cams are designed to improve low-end power delivery, making the engine feel more engaged and responsive, particularly in the critical 2,000 5,000 RPM range where the 2.7L excels. Whether you re chasing a sportier driving experience, preparing for track use, or simply aiming to restore the engine to its factory-intended performance levels, these cams offer a straightforward yet effective upgrade. Built to Porsche s exacting standards, they are compatible with the original engine bay layout, ensuring a seamless fit without the need for extensive modifications. For those who appreciate the balance of power and precision that defines Porsche engineering, these cams provide a subtle yet meaningful enhancement, allowing the 2.7L s natural charm to shine even brighter. Ideal for both restoration projects and performance-minded modifications, they represent a smart investment for anyone looking to preserve or elevate the character of their 987.1 or 997.20 Porsche.

### **Pros and Cons of Buying a Porsche 987.1 Boxster/Cayman (2006 2008) with a Left-Hand 4-6 Engine (M97.20 2.7L, 987.1, 2006 2008) with Cylinder Head and Camshaft Issues**

#### **Pros**

1. **Classic Porsche Driving Experience**

The 987.1 Boxster and Cayman are beloved for their lightweight construction, rear-wheel-drive dynamics, and engaging road manners. The 2.7L M97 engine (especially in the 996 s final years and early 987) delivers a smooth, naturally aspirated V6 sound and power delivery that remains enjoyable for enthusiasts.

2. **Strong Community and Aftermarket Support**

Porsche s 987 platform (and its predecessor, the 996) has a dedicated following. Parts, modifications, and tuning options are widely available, making maintenance and upgrades relatively straightforward. Common issues like camshaft and cylinder head problems have been well-documented, allowing buyers to research solutions before purchasing.

3. **Potential for Reliability with Proper Maintenance**

While the M97 engine is notorious for camshaft and cylinder head wear, many examples can be restored to good health with a **camshaft replacement, cylinder head overhaul, and valve spring replacement**. If the seller has documented maintenance (e.g., oil changes, camshaft service), the car may be in better shape than average.

4. **Lower Purchase Price Compared to Later Models**

The 987.1 is cheaper than newer Porsche models, making it an attractive entry point for enthusiasts who want a track-capable or daily-driving Porsche without the premium price of a 991 or 992.

5. **Modification Potential**

The M97 engine is a favorite for tuning, with options ranging from mild bolt-ons (intake, exhaust, ECU tweaks) to full engine builds (turbocharging, supercharging, or even swapping in a 9A engine). The lightweight chassis also responds well to weight reduction and suspension upgrades.

6. **Reliability Improvements Over Earlier 996 Models**

The 987.1 is an evolution of the 996, incorporating some reliability improvements (e.g., better cooling, revised suspension). While still not as refined as later models, it s a step up from the 996 s early camshaft failures.

---

#### **Cons**

1. **Camshaft and Cylinder Head Wear (Primary Concern)**

- **Excessive valve train noise** (ticking, rattling, or clattering from worn cam lobes).

- **Oil consumption** (common due to worn valve stem seals and piston rings).

- **Cylinder head cracks** (less common but possible, especially if the engine was overheated).

- **Valve spring failure** (can cause catastrophic engine damage if not addressed).

- **Rod bearing wear** (some examples show signs of this, requiring a full engine rebuild).

- Loud ticking or rattling from the valve cover (especially at idle or low RPM).

- Blue smoke from the exhaust (oil burning).

- Check engine lights for misfires or oil-related codes (e.g., P0010 P0014 for camshaft position issues).

- **Camshaft replacement** ( $1,500 $2,500 installed, depending on labor).

- **Cylinder head overhaul** (valve springs, retainers, guides, seals; $1,000 $2,000).

- **Full engine rebuild** (if rod bearings or other internal damage is present; $5,000 $10,000 ).

2. **Transmission Issues (Manual and PDK)**

- **Manual transmissions (6-speed):** Generally reliable but can develop **clutch wear** or **shift linkage issues** if not maintained.

- **PDK (semi-automatic):** More complex and prone to **fluid leaks, clutch pack wear, and electronic gremlins**. PDK models require more frequent servicing ( $1,500 $2,500 for a full rebuild).

3. **Electrical and Software Quirks**

- **Infotainment system** (if equipped) can be finicky, with **Bluetooth, USB, and navigation issues**.

- **Sensors and actuators** (e.g., oil level sensor, throttle position sensor) may fail over time.

- **Software updates** are limited compared to newer models, and some features (like adaptive cruise control) may not work as intended.

4. **Rust and Bodywork Concerns**

- Early 987.1 models (especially in snowy or humid climates) can suffer from **underbody rust** (subframe, control arms, exhaust).

- **Popping panels** (common in older Porsches) may require bodywork attention.

5. **Depreciation and Resale Value**

- While the 987.1 holds value better than the 996, it s not as desirable as the **991 (911) or 992 (Cayenne, 718)**. Resale depreciation is a factor if you plan to sell later.

6. **Maintenance Costs**

- **Oil changes** should be done **every 5,000 7,500 miles** (Porsche recommends synthetic every 10,000, but the M97 benefits from more frequent changes).

- **Timing belt replacement** ( $1,000 $1,500) is critical **never skip it** (the M97 is an interference engine).

- **Cooling system flushes** (every 3 5 years) to prevent head gasket issues.

- **Suspension components** (shocks, bushings, ball joints) wear out over time.

7. **Track and Performance Limitations**

- While the 987.1 is capable on track, it lacks the **aerodynamics, brakes, and power** of later models (e.g., 997 GT3, 991 GT3).

- **Tire wear** can be an issue due to the lightweight chassis and stiff suspension.

---

### **Ending Conclusion**

- **Understands and accepts the camshaft and cylinder head risks** (and is prepared for repairs).

- **Enjoys the driving experience** and doesn t mind occasional maintenance.

- **Plans to modify or restore the car** rather than drive it as-is.

- **Has access to a reliable mechanic** familiar with Porsche engines.

- **First-time Porsche owners** who want a hassle-free daily driver.

- **Buyers who prioritize reliability over character** (consider a **997 GT3, 991 911, or even a used 992 Cayman** instead).

- **Those unwilling to budget for potential engine work** (camshafts, cylinder heads, valve springs).

---

### **Recommendation**

- **Get a pre-purchase inspection (PPI) from a Porsche specialist** (or someone experienced with M97 engines).

- **Oil changes** (frequency and type of oil used).

- **Camshaft service history** (if the seller claims it s been done).

- **Timing belt replacement** (must be done at the manufacturer s interval).

- **Listen for camshaft noise** during the test drive (idle, low RPM, and under acceleration).

- **Check for oil leaks** (valve cover gasket, oil filter housing gasket).

- **Budget for potential repairs** **$3,000 $6,000** could be needed for camshafts, cylinder heads, and minor issues.

- **If you want a more reliable 987.1:** Look for a **right-hand 4-6 engine (M97.21)** these are slightly less prone to camshaft issues.

- **If you want a newer Porsche with better reliability:** Consider a **used 997 GT3 (2009 2012)** or **991 911 (2012 2019)**.

- **If you want a track-focused car:** A **997 GT3 or 991 GT3 RS** is a better long-term investment.

- **Buy it if:** You re an experienced mechanic, enjoy projects, and can afford the repairs. The **driving experience is unmatched
