Gates EMH015 Engine Crankcase Breather Hose - Valve Cover To Intake Tube

OE-Exact Crankcase Breather Hose

The Gates EMH015 is an OE-exact engine crankcase breather hose for emission control service. Built from plastic with a clip-on end, it restores the crankcase ventilation path between the valve cover and intake tube on select Chevrolet Silverado 1500, GMC Sierra 1500, and Chevrolet Silverado 2500 applications.

What This Hose Helps Address

• Cracked or brittle crankcase breather hose material
• Oil vapor or crankcase ventilation leaks at the hose connection
• Improper hose routing between the valve cover and intake tube
• Emission system performance issues caused by a damaged hose
• Fitment problems from non-OE-shaped replacement hoses

Installation Notes and Tips

Inspect the valve cover and intake tube connection points before installation and replace any damaged retaining clips or seals as needed. Confirm the hose routing matches the factory path and verify the clip-on ends are fully seated. Because this hose is application-specific, compare the original hose shape and length before installation.
