Gates Engine Crankcase Breather Hose PCV Valve to Intake

The Gates Engine Crankcase Breather Hose connects the PCV valve to the intake. It is also called a PCV hose or crankcase vent hose. It carries crankcase vapors and blow-by gases back into the intake system so they can be burned in the engine. This helps the engine's emission controls work as designed and helps keep crankcase pressure balanced.

Key Features:

• Made for the PCV system, where heat, oil vapor, and fuel vapor are present
• Built from materials chosen to resist oil, heat, and aging
• Designed as a direct replacement for the original hose
• Helps prevent oil leaks, vacuum leaks, rough idle, and increased emissions from a cracked or deteriorated breather hose
• Made by Gates, a long-time supplier of belts, hoses, and fluid-transfer components to the automotive aftermarket

Replace a hardened, cracked, collapsed, or oil-soaked breather hose to help restore proper crankcase ventilation. Check the PCV valve and any related hoses and clamps during the same service.
