Review PUROLATOR Crankcase Breather Filter 1980 89 Jeep Lot Of fits CJ5 CJ7 1980-89–2010

The **Purolator B13153 Crankcase Breather Filter** is a precision-engineered air filtration solution specifically designed to maintain optimal engine performance and longevity in classic Jeep CJ5 and CJ7 models produced between 1980 and 1989, as well as the 1980 Jeep 10. Engineered to meet the demanding requirements of these rugged, off-road vehicles, this filter plays a critical role in the crankcase ventilation system by preventing oil and contaminants from escaping while allowing proper airflow to circulate within the engine bay. Crafted from high-quality, oil-resistant materials, the Purolator B13153 ensures that harmful particles, moisture, and combustion byproducts are effectively trapped, safeguarding the engine s internal components from premature wear and corrosion. Its compact yet durable design fits seamlessly into the engine compartment of these iconic Jeeps, offering a reliable barrier against the harsh conditions often encountered during off-roading, dusty trails, or extreme climates. By maintaining clean crankcase airflow, this filter helps reduce engine sludge buildup, minimizes oil consumption, and contributes to smoother operation, ensuring that your Jeep s powerful V8 or inline-six engine remains in peak condition for years of dependable performance. Whether you're tackling rough terrain or cruising on the highway, the Purolator B13153 is an essential component for preserving the health of your Jeep s engine, delivering both performance and protection with every mile.

**Pros and Cons of buying a Purolator B13153 Crankcase Breather Filter for 1980 1989 Jeep CJ5/CJ7 (10-Speed Manual Transmission)**

### **Pros**

1. **Improved Engine Protection** The crankcase breather filter traps oil mist, contaminants, and moisture that can enter the engine through the PCV (Positive Crankcase Ventilation) system. This helps prevent sludge buildup, oil dilution, and carbon deposits, which can reduce engine longevity and performance.

2. **Enhanced Airflow and Efficiency** A clean or properly functioning breather system ensures that crankcase gases are expelled efficiently, reducing backpressure and improving engine breathing. This can lead to smoother operation, especially in older engines prone to carbon buildup.

3. **Prevents Oil Leaks and Contamination** By filtering out debris and moisture, the breather reduces the risk of oil leaks or contamination in the intake system, which can cause misfires, rough idling, or even engine damage over time.

4. **Extended Engine Life** Regularly replacing or maintaining the breather filter helps keep the engine cleaner internally, which can delay the need for costly repairs like valve cover gasket replacement, piston ring wear, or cylinder head issues.

5. **Easy Installation and Replacement** The Purolator B13153 is designed as a direct replacement for the OEM part in CJ5/CJ7 vehicles, making it straightforward to install without modifications. It typically requires minimal tools and can be done in under an hour.

6. **Cost-Effective Maintenance** Compared to major engine repairs, replacing a crankcase breather filter is a low-cost preventive measure (typically under $20 $30 for the filter alone). It s a small investment that can save hundreds or thousands in long-term engine damage.

7. **Compatibility with Modifications** If your CJ5/CJ7 has aftermarket modifications (e.g., turbocharging, forced induction, or high-performance exhaust), a high-quality breather filter helps manage increased crankcase pressure and contaminants more effectively.

8. **Reduced Emissions (Indirectly)** While not a primary function, a clean breather system helps maintain proper combustion efficiency by preventing oil fouling in the intake, which can indirectly reduce harmful emissions.

### **Cons**

1. **Potential for Clogging Over Time** Like any filter, the Purolator B13153 can become clogged with oil sludge, dirt, or debris if not replaced at the recommended intervals (usually every 10,000 20,000 miles or as part of an oil change service). A clogged filter can restrict airflow, negating its benefits.

2. **Oil Consumption Concerns** Some drivers report that certain crankcase breather filters (including aftermarket options) may contribute to increased oil consumption if the system isn t properly sealed or if the filter is too restrictive. However, the Purolator B13153 is designed to balance filtration and airflow, minimizing this risk.

3. **Limited Lifespan** The filter itself is not designed to last indefinitely. Neglecting replacement can lead to a buildup of contaminants, reducing its effectiveness and potentially causing issues like oil leaks or engine fouling.

4. **Installation Challenges in Older Vehicles** While the B13153 is a direct fit, some CJ5/CJ7 engines may have worn or corroded breather hoses or connections. If these aren t addressed during installation, leaks or improper sealing could occur, defeating the purpose of the filter.

5. **Mixed Reviews on Durability** Some users report that aftermarket crankcase breather filters (even reputable brands like Purolator) may not last as long as OEM parts in high-mileage or heavily modified engines. Over time, the filter material can degrade, requiring more frequent replacements.

6. **Not a Cure for Major Engine Issues** While the breather filter helps with minor contaminants, it won t fix severe engine problems like worn piston rings, valve stem seals, or head gasket leaks. Drivers with existing engine issues may need additional diagnostics or repairs.

7. **Potential for Over-Tightening** During installation, over-tightening the filter housing or hoses can damage O-rings or threads, leading to leaks. It s important to follow the manufacturer s torque specifications (if provided) or use a gentle hand during installation.

### **Conclusion and Recommendation**

The **Purolator B13153 crankcase breather filter** is a **highly recommended upgrade or replacement part** for 1980 1989 Jeep CJ5/CJ7 vehicles, particularly those with manual transmissions. Its primary benefits protecting the engine from contaminants, improving airflow, and extending component life make it a worthwhile investment for both maintenance and performance.

**Key Considerations Before Purchase:**

- **Replacement Intervals:** Replace the filter every **10,000 20,000 miles** or as part of your oil change routine to ensure optimal performance.

- **Inspect the System:** While installing the new filter, check the **breather hoses, PCV valve (if equipped), and valve cover gasket** for leaks or wear. Replace any damaged components to prevent future issues.

- **Pair with Other Maintenance:** Combine this upgrade with regular **oil changes, air filter replacements, and valve cover gasket inspections** for comprehensive engine care.

- **Budget-Friendly Alternative:** If cost is a concern, consider **OEM-style aftermarket filters** from brands like **WIX or Mann-Filter**, which offer similar protection at comparable prices.

**Final Verdict:** The Purolator B13153 is a **solid choice** for CJ5/CJ7 owners looking to maintain or restore their engine s health. Its ease of installation, proven effectiveness, and affordability make it a **strong recommendation** for both new and experienced Jeep enthusiasts. If your vehicle shows signs of oil fouling, rough idling, or excessive crankcase pressure (e.g., oil leaks from the breather hose), installing this filter should be a priority.
