The Multiquip 0191500770 Blowby Hose is a genuine OEM component designed for DCA70SSIU2 and MQP56 diesel-powered generators. As a factory-sourced part, it meets the exact specifications of the original component, ensuring proper fit and function within the engine ventilation circuit. This hose is sold by DHS Equipment, an authorized Multiquip parts distributor, so you can order with confidence knowing you are receiving an authentic replacement. Verify your model code against the fitment data — DCA70SSIU2 and MQP56 — before ordering to confirm compatibility.
Key Features
- Genuine OEM Construction — Manufactured to the original material and dimensional specifications for the blowby ventilation circuit, ensuring the hose handles crankcase pressure and temperature demands without degradation.
- Direct-Fit Replacement — Engineered to connect to the existing fittings and routing path on the DCA70SSIU2 and MQP56, requiring no trimming, adapting, or modification to the hose ends or clamp positions.
- Confirmed Generator Fitment — Specifically compatible with Multiquip DCA70SSIU2 ultra-silent and MQP56 standby diesel generator models.
- Crankcase Ventilation Integrity — A properly functioning blowby hose routes crankcase gases safely away from the engine, preventing oil contamination and maintaining clean combustion air supply to the intake.
- Emissions and Engine Compliance — Correctly routing blowby gases is essential for meeting engine emissions standards; a cracked or failed hose can introduce unmetered air into the intake and trigger oil consumption issues or diagnostic faults.
The blowby hose is a critical part of the engine's crankcase ventilation system. As an engine runs, combustion gases that slip past the piston rings — known as blowby — build up inside the crankcase and must be routed out to prevent pressure buildup and oil contamination. This hose channels those gases back into the intake or to a designated vent point, keeping the engine breathing cleanly. When the hose cracks, collapses, or deteriorates, crankcase pressure rises, oil leaks become more likely, and the engine's intake may draw in unfiltered air or oil vapor, accelerating internal wear.
