The Multiquip 0191500680 is a genuine OEM Blowby Hose designed for DCA70USI2 and DCA70USI3CAN ultra-silent diesel generators. As a direct OEM replacement, this hose is manufactured to the exact specifications of the original component, ensuring a proper fit within the engine ventilation system. Sourced directly from Multiquip, it is the correct part for maintaining the crankcase ventilation integrity of your DCA-series generator.
Key Features
- Genuine OEM Construction — Manufactured to the original material and dimensional specifications required for crankcase ventilation in diesel generator applications, ensuring consistent sealing and flow performance.
- Direct Drop-In Replacement — Routes and connects exactly as the original, following the same path and connection points within the engine compartment of compatible DCA-series units.
- Confirmed Fitment — Verified for the DCA70USI2 and DCA70USI3CAN ultra-silent diesel generator models.
- Crankcase Pressure Management — A properly functioning blowby hose routes combustion gases safely away from the engine, preventing pressure buildup that can lead to oil leaks and premature seal wear.
- Emissions and Engine Health — Correct routing of blowby gases is critical to engine cleanliness and emissions compliance; a cracked or failed hose can allow unfiltered gases to contaminate surrounding components.
The blowby hose is part of the engine's crankcase ventilation system, responsible for routing combustion gases that bypass the piston rings back into the intake or exhaust system rather than allowing them to accumulate inside the crankcase. This controlled venting prevents excess pressure from building up, which can force oil past gaskets and seals and lead to costly engine damage. When this hose cracks, hardens, or loses its seal, you may notice oil leaks, increased oil consumption, or visible smoke — all signs that the ventilation circuit is no longer functioning as intended.
