URO 997-107-143-01 Engine Crankcase Vent Hose

The URO 997-107-143-01 is a direct-fit replacement crankcase vent hose designed to restore proper engine ventilation system function. URO Parts manufactures this hose to match the original equipment specifications, providing a cost-effective alternative to the Porsche OEM part.

The crankcase vent hose plays a critical role in the positive crankcase ventilation (PCV) system, routing blow-by gases from the engine crankcase back into the intake system for combustion. Over time, these hoses are prone to cracking, hardening, or collapsing due to heat cycling and oil exposure, which can lead to rough idle, oil leaks, or increased emissions.

Key Features:

• Direct OEM replacement fit — no modifications required
• Manufactured to match original equipment dimensions and routing
• Resistant to oil, heat, and engine chemicals
• Restores proper crankcase pressure management
• Helps prevent oil leaks and rough idle caused by a failed vent hose
• Porsche OEM reference: 997-107-143-01
