Review GATES Buick Crankcase Breather Hose fits REGAL 2014–2017

The **Gates 86479DTSK Crankcase Breather Hose** is a high-performance, precision-engineered replacement part designed specifically for the 2014 2015 and 2017 Buick Regal, ensuring optimal engine efficiency and longevity. Crafted from Gates proprietary **EPDM (Ethylene Propylene Diene Monomer) rubber compound**, this hose delivers exceptional resistance to oil, heat, and environmental contaminants, making it ideal for under-the-hood applications where durability and reliability are critical. The reinforced construction prevents cracking, swelling, or premature degradation, even under prolonged exposure to engine heat and vacuum fluctuations, which are common in modern turbocharged or high-performance powertrains. This crankcase breather hose plays a vital role in maintaining proper engine breathing by filtering and routing crankcase gases away from critical components, reducing oil consumption, and minimizing emissions while preventing harmful carbon buildup in intake systems. Its **tight-fitting, interference-free design** ensures a secure seal at both ends, preventing leaks that could compromise engine performance or trigger check engine lights. Whether installed during routine maintenance or as part of a performance upgrade, the Gates 86479DTSK provides a direct, drop-in replacement that meets or exceeds OEM specifications, offering peace of mind for drivers seeking a dependable solution. Built to withstand the demands of daily driving and extended use, this hose exemplifies Gates commitment to quality, ensuring seamless integration with the Buick Regal s engine bay for years of trouble-free operation.

### **Pros and Cons of buying a Gates 86479DTKS Crankcase Breather Hose for 2014-2015 & 2017 Buick Regal**

1. **OEM Fitment and Compatibility** The Gates 86479DTKS is designed as an original equipment replacement part for the specified Buick Regal models, ensuring an exact fit without modifications. This reduces the risk of leaks or improper installation.

2. **High-Quality Materials** Gates is a reputable manufacturer known for durable rubber and reinforced construction, which helps prevent premature cracking, hardening, or failure due to heat, oil, or engine contaminants.

3. **Prevents Engine Contamination** A failing crankcase breather hose can allow oil vapors and particles to enter the intake system, clogging the air filter and damaging the engine over time. A proper replacement ensures clean airflow and protects internal components.

4. **Easy Installation** The hose is designed for straightforward replacement, typically requiring only basic tools. Many buyers report that it can be installed in under an hour with minimal effort.

5. **Cost-Effective Long-Term Solution** While the upfront cost is moderate, replacing the hose prevents costly engine damage (e.g., carbon buildup, intake restrictions) that could arise from a failing breather system.

6. **Warranty Coverage** Gates parts often come with manufacturer warranties, providing peace of mind against defects in materials or workmanship.

7. **Prevents PCV System Issues** The crankcase breather is part of the PCV (Positive Crankcase Ventilation) system. A bad hose can disrupt proper ventilation, leading to pressure buildup, oil leaks, or even a blown gasket. Replacing it maintains system efficiency.

3. **Installation Challenges for DIYers** Though generally simple, some Buick Regal models may require removing the air intake or other components to access the hose. Those unfamiliar with engine bay work might struggle.

4. **Limited Longevity Compared to OEM** While Gates is high-quality, some users report that aftermarket hoses may not last as long as the original equipment part, especially in high-mileage or severe-service vehicles.

5. **Compatibility Confusion** The part number (86479DTKS) is specific to the 2014-2015 and 2017 Buick Regal. Buyers must verify their exact model year and engine configuration to avoid purchasing the wrong part.
