Product Details

Gates EMH998 is part of the Gates Crankcase Vent Valve line, which focuses on OE-style crankcase ventilation pressure regulators, PCV valves, and oil separators. This product is engineered to match the original configuration closely so the emission ventilation system can be returned to normal operation and performance. It is a direct service part for vehicles that need a replacement crankcase vent valve rather than a universal component.

It fits 2018-2022 Chevrolet Equinox and 2018-2021 GMC Terrain, making it a targeted choice for owners searching for a 2018-2022 Chevrolet Equinox crankcase vent valve or a 2018-2021 GMC Terrain PCV valve replacement. The Gates EMH998 also appears in searches for OE-style crankcase ventilation repair on these models.

Common Issues This Part Can Address

  • Crankcase ventilation system fault codes related to pressure regulation
  • Rough idle caused by a worn or restricted PCV-style valve
  • Oil vapor control problems in the emission ventilation system

  • Failed inspection results linked to crankcase ventilation performance
