The GATES EMH440 crankcase ventilation hose is engineered to maintain optimal engine performance by managing crankcase pressure. This component plays a crucial role in venting blow-by gases from the crankcase back into the intake system for re-combustion, thereby reducing emissions and preventing oil leaks.

A damaged or clogged hose can lead to increased oil consumption, sludge formation, and premature wear of internal engine components. Replacing your old hose with a GATES EMH440 ensures reliable operation and helps maintain the integrity of your engine's oil system.
