🔧 Product Description
Genuine Volvo Penta formed lubrication oil line replacing earlier reference 3885721. It transfers pressurised or return oil through the assigned engine circuit using the factory tube geometry and connection positions.
⚙️ Key Features
- Genuine Volvo Penta engine oil line
- Supersedes earlier oil-line reference 3885721
- Rigid formed line with OEM connection geometry
- Part-number and engine- application
- Flush and inspect the connected oil circuit before installation
- Engine type: Volvo Penta marine or industrial diesel lubrication system
🔌 Function
Carries engine oil through the assigned pressure or return circuit while maintaining unrestricted flow and correct routing.
⚠️ Common Signs of Failure
- Oil leakage or staining at the pipe, hose or fittings
- Low oil pressure or delayed pressure rise
- Cracking, chafing or vibration fatigue near supports
- Internal restriction caused by sludge, carbon or damaged lining
- Oil starvation, overheating or accelerated wear of the supplied component
🛠️ Service Notes
- Work clean and cap or plug both the line and its ports as soon as they are open — anything that gets into an oil line ends up at a bearing or in the turbocharger
- Renew the sealing washers, O-rings or gaskets at each end rather than reusing them, and start unions by hand so the seal is not loaded sideways
- Do not bend or reshape a line to make it reach; a line strained into place fatigues and cracks at the union
- Refit every clip and support bracket in its original position — an unsupported oil line chafes and fails through vibration
- After fitting, check oil level, run the engine and check the unions for leaks and the oil pressure for normal reading, then check again once hot
