Review DUCATI Blow by Breather Valve Oem fits DIAVEL MONSTER SUPERSPORT 1200 2012

The **Ducati 59320581B Diavel Monster 1200 Supersport Blow-By Breather Valve (2012)** is a precision-engineered component designed specifically for Ducati s high-performance liquid-cooled V-twin engines, ensuring optimal airflow and longevity in demanding riding conditions. This breather valve is a critical part of the engine s ventilation system, responsible for regulating the flow of gases within the crankcase to prevent excessive pressure buildup, which can lead to leaks, oil contamination, or even catastrophic engine failure. Crafted from high-quality materials, the valve features a robust, durable construction that is engineered to withstand the extreme temperatures and pressures generated by Ducati s aggressive power delivery, particularly in models like the Diavel Monster and the 1200 Supersport, which are known for their aggressive riding dynamics and high-revving nature. The valve s design incorporates a precise internal mechanism that allows for smooth, controlled airflow while minimizing oil loss and maintaining engine efficiency. This component is particularly essential for riders who push their bikes to their limits, whether on twisty backroads, track days, or high-speed runs, as it helps mitigate the effects of blow-by a byproduct of combustion that can degrade engine performance if not properly managed. Installing this OEM-spec valve ensures that the engine operates within its intended parameters, reducing the risk of oil dilution, crankcase pressure fluctuations, and premature wear on seals and gaskets. Whether used in a stock configuration or as part of a performance upgrade, this breather valve exemplifies Ducati s commitment to engineering reliability and performance in its iconic motorcycles.

### **Pros and Cons of Buying a 2012 Ducati Diavel (59320581B) with a Blow-by Breather Valve Issue**

#### **Pros**

1. **Strong Performance and Reputation**

The Ducati Diavel is a well-regarded naked bike known for its aggressive styling, powerful engine, and engaging riding experience. The 1,200cc L-Twin engine delivers strong torque and a distinctive Ducati sound, making it a fun ride for both street and light track use.

2. **Reliability of the Base Model**

The 2012 Diavel is based on Ducati s proven L-Twin architecture, which was (and still is) known for durability when properly maintained. Many early L-Twin engines, including those in the Diavel, are robust if serviced regularly.

3. **Aftermarket Support and Customization**

Ducati s L-Twin platform has a vast aftermarket presence, meaning parts like exhausts, ECU tuning, and suspension upgrades are widely available. This makes it easier to modify the bike to suit personal preferences.

4. **Comfortable Riding Position**

The Diavel s ergonomics are designed for both comfort and aggression. The upright riding position makes it suitable for longer rides, while the aggressive stance appeals to those who prefer a sportier feel.

5. **Resale Value (Compared to Some Ducatis)**

While not as high as newer models, the Diavel retains decent resale value due to its popularity and Ducati s brand strength. This can be an advantage if you plan to sell it later.

6. **Blow-by Breather Valve as a Manageable Issue**

The blow-by breather valve (part number 59320581B) is a common wear item in Ducati L-Twin engines, particularly in older models. While it indicates some internal wear, it is often an isolated issue rather than a sign of catastrophic engine failure. Many owners replace it as a routine maintenance step rather than a major repair.

---

#### **Cons**

1. **Blow-by Issue Indicates Internal Wear**

A failing blow-by breather valve typically means the piston rings or cylinder walls are wearing out, allowing combustion gases to escape past the rings. This can lead to reduced compression, power loss, and increased oil consumption. While not always a dealbreaker, it suggests the engine has seen significant mileage and may require further inspection (e.g., compression test, oil consumption check).

2. **Age and Mileage Concerns**

A 2012 Diavel is now over a decade old, meaning it has likely accumulated high mileage (especially if not well-maintained). Ducati s L-Twin engines are durable, but wear and tear become more noticeable over time. Rust, chain stretch, and suspension wear are also common issues in older bikes.

3. **Maintenance Costs**

Ducati parts and labor can be expensive, particularly for specialized components like the blow-by valve or exhaust systems. If the bike has been neglected, additional repairs (e.g., valve seals, timing chain, or clutch) may be needed, adding to the cost.

4. **Potential for Hidden Problems**

A bike with a known issue like the blow-by valve may have other underlying problems that haven t been addressed. Always inspect the bike thoroughly (or have a mechanic do so) to check for:

- Oil leaks (valve cover gasket, oil filter housing)

- Chain and sprocket wear

- Suspension condition (shocks, forks)

- Electrical gremlins (common in older Ducatis)

5. **Depreciation**

While the Diavel holds value better than some Ducatis, it is still a depreciating asset. If you plan to keep it long-term, the cost of ownership (fuel, insurance, maintenance) may outweigh the enjoyment for some riders.

6. **Noise and Vibration**

The L-Twin engine is loud and has a distinctive (some would say obnoxious) exhaust note. While many riders love this, others may find it intrusive, especially in urban areas. Additionally, the engine can feel rough at idle, which may not suit casual riders.

---

### **Conclusion**

- The bike has been well-maintained (service records are available).

- The engine passes a compression test and shows no other signs of severe wear.

- You are prepared for potential additional repairs (e.g., rings, seals) and the associated costs.

- You enjoy Ducati s performance and styling and are willing to invest in its upkeep.

- The bike has high mileage with no maintenance history.

- The blow-by issue is accompanied by other red flags (oil burning, rough running, leaks).

- You are not comfortable with the cost of ownership (parts, insurance, fuel), then it may not be the best purchase.

### **Recommendation**

1. **Get a Pre-Purchase Inspection (PPI)** from a trusted Ducati mechanic. This should include a compression test, oil consumption check, and inspection of the timing chain, valves, and suspension.

2. **Budget for Potential Repairs**. If the engine is worn but repairable, factor in the cost of replacing the blow-by valve, piston rings, or other components as needed.

3. **Negotiate the Price**. If the seller is aware of the blow-by issue and the bike has other flaws, use this to your advantage in price negotiations.

4. **Consider a Lower-Mileage Alternative**. If possible, look for a Diavel with lower mileage and a complete service history to avoid unexpected repairs.

Ultimately, the Diavel is a fantastic bike when in good condition, but the blow-by valve issue is a warning sign that requires careful evaluation. If you are willing to invest time and money into restoring it, it can be a rewarding purchase. If not, you may want to consider a newer model or a different brand with lower maintenance risks.
