Manufactured to original equipment specifications, this high-quality replacement oil tank provides the correct capacity, mounting points and pipe connections required for the Porsche dry sump lubrication system. It is an ideal solution for replacing corroded, damaged or leaking original tanks during restoration or engine rebuild projects.

The dry sump oil tank is one of the most important components of every classic air-cooled Porsche engine. It stores, cools and supplies engine oil while ensuring a constant supply of lubricant under all driving conditions, even during hard cornering and high engine speeds.

What Does the Engine Oil Tank Do?

Unlike a conventional wet sump engine, the Porsche flat-six uses a dry sump lubrication system, with engine oil stored in a separate external tank.

The oil tank performs several vital functions:

• Stores the engine's oil supply.
• Supplies oil to the pressure pump.
• Receives oil returned from the engine via the scavenge pump.
• Assists with oil cooling.
• Allows air to separate from the returning oil before recirculation.
• Maintains a constant oil supply during spirited driving and cornering.

The oil tank is fundamental to the legendary reliability of Porsche's air-cooled flat-six engine.

Why Does the Oil Tank Need Replacing?

After decades of service, original oil tanks often deteriorate due to age and environmental exposure.

Common causes include:

• Internal corrosion.
• External rust caused by road moisture.
• Stone impact damage.
• Fatigue around welded seams.
• Oil contamination from accumulated debris.
• Previous accident damage.
• Distortion caused by incorrect repairs.

Replacing a damaged oil tank helps restore the integrity of the lubrication system and protects your engine from costly damage.

Symptoms of a Failing Engine Oil Tank

Typical warning signs include:

• Engine oil leaks.
• Corrosion around the lower section of the tank.
• Rust around welded seams.
• Oil stains beneath the vehicle.
• Contaminated engine oil.
• Damaged pipe connections.
• Poor sealing around fittings.

Any oil leak within the lubrication system should be investigated immediately to prevent low oil levels and potential engine damage.

When Should the Engine Oil Tank Be Replaced?

Replacement is recommended when:

• Oil leaks develop.
• Corrosion becomes visible.
• Restoring a classic Porsche.
• Carrying out a complete engine rebuild.
• Replacing damaged lubrication components.
• Internal contamination cannot be removed.
• The tank has suffered accident damage.

Installing a new OE Match oil tank helps restore dependable lubrication and long-term engine reliability.
