The Multiquip M5327100004 Blowby Pipe is a genuine OEM component designed for the DCA220SSJU4F series Super-Silent and diesel powered generators. As an authorized Multiquip OEM part, M5327100004 is manufactured to the exact specification of the original, ensuring a direct fit into the engine ventilation circuit of compatible DCA220SSJU4F units. DHS Equipment supplies this part with verified part number accuracy so you can order with confidence. Cross-reference your model code against the DCA220SSJU4F and DCA220SSJU4F2 fitment list before ordering to confirm compatibility.
Key Features
- OEM-Grade Tube Construction — Manufactured from the same material and to the same dimensional tolerances as the original, maintaining proper blowby flow routing in the engine crankcase ventilation system.
- Direct-Fit Installation — Engineered to connect at the exact attachment points of the DCA220SSJU4F engine assembly, dropping into place without rework or modification to adjacent components.
- Confirmed Fitment — Compatible with DCA220SSJU4F and DCA220SSJU4F2 Super-Silent and diesel powered generator models in both standard and 60Hz configurations.
- Crankcase Pressure Control — A correctly functioning blowby pipe maintains proper crankcase pressure balance; a cracked, blocked, or disconnected pipe can allow oil mist and combustion gases to contaminate the intake or escape into the enclosure.
- Emissions and Engine Health Compliance — Proper routing of crankcase blowby gases is essential for meeting engine emissions requirements; using the correct OEM pipe keeps the ventilation path sealed and compliant.
The blowby pipe is part of the engine's crankcase ventilation system, responsible for routing combustion gases that have passed the piston rings — known as blowby gases — away from the crankcase and back into the intake or to a safe discharge point. This prevents pressure buildup inside the engine that would otherwise force oil past seals and gaskets. When the blowby pipe cracks, collapses, or pulls loose from its fittings, the result is uncontrolled oil leaks, elevated crankcase pressure, and potential contamination of the generator's enclosure or intake system, all of which can accelerate engine wear and affect generator output stability.
