Oil pipe tank to engine. Porsche 911 1975-77  ›  91110774210

The OE Match Oil Pipe Tank to Engine is a replacement lubrication-system component designed for classic Porsche 911 models equipped with the dry-sump engine oil system.

• Porsche 911 1975-77

The pipe forms part of the oil circuit between the vehicle's external oil reservoir and the engine, providing a secure route for engine oil to circulate through the lubrication system. Maintaining an unrestricted and leak-free oil supply is essential for protecting bearings, valvetrain components and other internal engine parts.

On an air-cooled Porsche 911, engine oil also makes an important contribution to temperature control. A leaking, crushed, corroded or otherwise damaged oil pipe can therefore affect both lubrication and effective heat management.

What This Product Does:

• Carries engine oil between the external oil tank and the engine.
• Forms an important part of the Porsche dry-sump lubrication system.
• Helps maintain a reliable supply of oil to the engine.
• Supports lubrication of bearings and other internal moving components.
• Contributes to engine cooling through effective oil circulation.
• Maintains a secure and sealed oil-system connection.
• Provides an unrestricted route for oil flow.
• Replaces an original pipe that has become corroded, leaking, crushed or damaged.
• Helps restore lubrication-system integrity during engine repair or vehicle restoration.

The dry-sump lubrication system relies on external pipework to move oil between the engine and separate oil reservoir, making the condition of these lines important to reliable engine operation.

Symptoms Of Wear Or Failure:
Possible signs of deterioration include:

• Visible engine oil leaking underneath the vehicle.
• Oil seepage around the pipe or threaded connections.
• Wet or oily deposits along the pipe.
• Gradual reduction in engine oil level.
• Oil spots appearing where the vehicle is parked.
• Burning-oil smell.
• Smoke if leaked oil reaches hot engine or exhaust components.
• Visible corrosion or rust on the pipe.
• Crushed, kinked or flattened sections.
• Damaged or seized fittings.
• Cracks around connections or mounting points.
• Oil contamination across surrounding chassis components.
• Evidence of previous temporary or poor-quality repairs.
• Reduced oil circulation if the pipe becomes internally restricted.

A pipe does not have to be visibly leaking to be defective. Crushing or deformation can reduce the internal cross-section and interfere with oil flow.

Why Replacement Matters:
The engine depends on a continuous supply of clean engine oil for lubrication and cooling.

If an external oil line begins to leak, the available oil quantity can gradually fall. Severe oil loss can eventually compromise lubrication and increase the risk of damage to expensive internal engine components.

Components that depend on reliable oil circulation include:

• Crankshaft bearings.
• Connecting-rod bearings.
• Camshafts and valvetrain components.
• Pistons and cylinders.
• Intermediate-shaft components.
• Other lubricated internal engine parts.

Replacing a deteriorated pipe helps restore a sealed and dependable oil circuit.
