Gates EMH291 Engine Crankcase Breather Hose - Valve Cover To Valve Cover

OE-Exact Crankcase Breather Hose

Gates EMH291 is an OE-exact engine crankcase breather hose for emission control service. Built from rubber with molded push-in ends, it restores the crankcase ventilation path on select Nissan applications, including Frontier, Xterra, Pathfinder, and NV-series vans.

The Gates Emission Control Hose line focuses on direct-fit replacement hoses for crankcase ventilation and emission routing. EMH291 follows the original hose shape and connection style to help maintain proper vapor flow and factory-style routing in the emission system.

What This Hose Helps Address

• Cracked or hardened crankcase breather hose material
• Oil vapor routing issues in the emission control system
• Vacuum leaks caused by deteriorated hose connections
• Broken or loose push-in hose ends
• Factory routing problems on Nissan Frontier, Xterra, Pathfinder, and NV vans

Installation Notes

Verify the hose routing, end style, and dimensions before installation. EMH291 uses push-in ends and a molded shape, so it should be installed in the same valve cover to valve cover path as the original hose. Inspect nearby breather and PCV-related components for wear before reassembly.

Quality Assurance

Gates designs this Emission Control Hose line as OE-exact replacement tubing for crankcase ventilation and emission service. EMH291 is built to match the original application requirements for fit, routing, and long service life.
