The Multiquip 0191601700 Blowby Hose is a genuine OEM component designed for DCA220SSJ, DCA220SSJU, and DCA180SSJU ultra-silent diesel generators. As a direct factory replacement, this hose restores proper crankcase ventilation and ensures the engine breathes exactly as designed. Sourced directly through the Multiquip OEM supply chain, the part is the correct specification part for these generator models. Keep your DCA-series generator running clean and compliant by replacing worn or damaged hose with the genuine article.
Key Features
- OEM-Grade Hose Material — Manufactured to the same material and dimensional specification as the original, ensuring proper sealing under sustained crankcase pressure and heat cycling typical of diesel generator operation.
- Direct Drop-In Replacement — Routes and connects identically to the factory hose, fitting the OEM barb and routing path without alteration to brackets or clamps.
- Confirmed Fitment — Compatible with DCA220SSJ, DCA220SSJU, and DCA180SSJU ultra-silent diesel generator models.
- Maintains Crankcase Ventilation Efficiency — A correctly functioning blowby hose routes combustion gases safely away from the crankcase, protecting engine oil quality and preventing pressure buildup that can accelerate seal wear.
- Fuel and Emissions System Integrity — A failed or cracked blowby hose allows unmetered air or uncontrolled blowby gases into the intake path, which can affect combustion consistency and emissions compliance on diesel-powered equipment.
The blowby hose is part of the engine's crankcase ventilation system, responsible for routing combustion gases — known as blowby — that escape past the piston rings during normal engine operation. These gases are directed back into the intake system or to a safe venting point rather than being released into the surrounding environment or allowed to pressurize the crankcase. When this hose cracks, collapses, or pulls free from its fittings, the engine may develop excessive crankcase pressure, oil leaks at seals and gaskets, or rough running due to uncontrolled air entering the intake. On a diesel generator like the DCA-series, maintaining a sealed and functional crankcase ventilation path is essential to consistent power output and engine longevity.
