21553338 Oil Line | Genuine Volvo Penta Part

🔧 Product Description

A rigid turbocharger lubricating-oil feed line used on later-production Volvo Penta TAD750VE and TAD760VE engine installations.

⚙️ Key Features

• Turbocharger pressure-oil supply
• Applicable from engine serial number 10550768 onward
• Precision-formed steel pipe
• Correct turbocharger and block connection geometry
• Replaces earlier line references

🔌 Function

The line supplies pressurised engine oil to the turbocharger bearing housing.

⚠️ Common Signs of Failure

• Oil seepage at unions
• Restricted turbocharger lubrication
• Turbocharger bearing noise or seizure
• Cracked line from vibration
• Blue exhaust smoke following turbocharger damage

🛠️ 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
