What This Hose Helps Address

• Cracked, hardened, or oil-soaked breather hose material
• Vacuum leaks in the crankcase ventilation path
• Unstable idle caused by unmetered air entering the intake
• Oil vapor routing issues in the emission control system
• Inspection failures related to damaged crankcase ventilation plumbing

Installation Notes and Tips

Inspect the mating ports, nearby PCV components, and intake connections before installation. Replace any brittle or damaged seals, and verify the hose is routed without kinks or collapse. Because clamp included is listed as no, confirm the required retaining method for your vehicle before service.

Quality Assurance

Standard Ignition supplies emission control service parts for OE-style repair applications. V770 is built as a replacement crankcase breather hose for the listed GM fitments, including Chevrolet Silverado, Tahoe, Avalanche, and Cadillac Escalade platforms.
