The Genie 33957GT is a genuine OEM PCV Valve designed for Ford large-displacement engines powering a wide range of Genie telescopic booms, articulating booms, and GS scissor lifts. Sourced directly from Genie, this part meets the same specifications as the component installed at the factory, ensuring a correct, trouble-free fit. Confirmed fitment includes popular models such as the S-60, S-65, S-80, S-85, Z-45/25J IC Power, Z-60/34, Z-80/60, GS-3390, GS-4390, and GS-5390, among others. Cross-reference part number 33957GT against your machine's parts manual to verify compatibility before ordering.
Key Features
- Genuine OEM Engine Part — Built to the same specification as the original valve, ensuring correct crankcase pressure regulation for Ford large-displacement engines used in Genie equipment.
- Direct-Fit Replacement — Connects to the existing valve cover port and intake plumbing without modification, restoring the OEM ventilation circuit as designed.
- Broad Genie Fleet Compatibility — Fits a wide range of Genie S-series telescopic booms, Z-series articulating booms, and GS rough-terrain scissor lifts powered by compatible Ford engines.
- Protects Engine Internals — A functioning PCV valve prevents crankcase pressure buildup that can force oil past seals and gaskets, keeping the engine running cleanly and extending its service life.
- Emissions and Operational Compliance — A correctly operating PCV valve is part of the engine's closed crankcase ventilation system; a failed valve can cause rough idle, oil consumption, and failed emissions checks on regulated jobsites.
The PCV (Positive Crankcase Ventilation) valve is a small but critical engine component that routes combustion blow-by gases from the crankcase back into the intake manifold to be burned, rather than venting them to atmosphere. This keeps crankcase pressure in check, prevents sludge buildup inside the engine, and protects oil seals from being forced out by excess pressure. When the valve sticks open, it allows too much airflow and can cause a rough idle or lean-running condition; when it sticks closed, pressure builds in the crankcase, leading to oil leaks, accelerated wear, and potential engine damage. Replacing a worn or stuck PCV valve is a straightforward service step that restores proper engine breathing and helps maintain peak performance in the demanding duty cycles typical of aerial lift and scissor lift applications.
