Manufactured from precision CNC-machined aluminium alloy, these collapsible oil tubes offer improved durability and easier installation compared with conventional rigid oil return pipes.
Supplied as a individually with replacement seals, four kits are needed per engine and these are ideal for repairing engine oil leaks, replacing ageing oil return pipes or carrying out a comprehensive engine restoration.
What Does the Collapsible Oil Tube Do?
The oil return tubes allow engine oil to drain from the cylinder head and valve gear areas back towards the engine crankcase.
This return flow is an important part of the engine's lubrication system, allowing oil to circulate correctly while preventing it from escaping through the engine casing.
The collapsible design allows the tubes to be compressed during installation and extended into position, making replacement considerably easier than fitting conventional one-piece rigid tubes.
Why Do Oil Return Tubes Fail?
Original oil return tubes and their seals are exposed to repeated heating and cooling cycles, engine vibration and general ageing.
Common causes of failure include:
Hardened or deteriorated rubber O-ring seals Corrosion of original metal oil tubes Cracked or damaged tube sections Distortion caused by previous repairs Incorrect installation or damaged sealing surfaces Long-term exposure to engine heat and oil contaminationIn many cases, oil leaks develop because the original seals lose their flexibility and can no longer maintain an effective seal.
When Should They Be Replaced?
Replacement is recommended when the oil return tubes show visible corrosion, physical damage or signs of oil leakage.
Common symptoms include:
Oil dripping from beneath the engine Wet or oily areas around the return tubes Burning oil smells caused by oil reaching hot exhaust components Increasing oil consumption due to external leakage Deteriorated or hardened oil tube sealsThe tubes should also be inspected during engine rebuilding, cylinder head servicing or restoration work.
Why Upgrade to CNC Alloy Collapsible Oil Tubes?
The CNC-machined aluminium alloy construction provides a durable replacement for ageing original components.
Unlike rigid oil return tubes, the collapsible design allows the replacement tubes to be fitted without the extensive dismantling normally associated with removing fixed-length tubes.
This makes them particularly useful for repairing oil leaks while the engine remains assembled.
Replacing all four tubes together also provides an opportunity to renew the complete set of seals, reducing the likelihood of further leaks from other ageing tubes.
Installation Notes
Before installation, inspect the oil return tube mounting points and sealing surfaces for damage or contamination.
Lubricate the replacement seals with a suitable lubricant, install the tubes in their compressed position and extend them fully into the correct mounting locations.
Ensure the tubes are correctly seated and secured according to the manufacturer's instructions.
Following installation, run the engine and inspect the repaired areas for oil leaks.
Porsche 911, 964 & 993 Collapsible Oil Return Tubes and Engine Lubrication Parts
The engine oil return tubes are essential components of the air-cooled Porsche flat-six lubrication system, allowing oil to return from the cylinder head assemblies to the crankcase.
Over time, original oil return tubes can develop leaks due to corrosion, damaged seals and repeated engine heat cycles. These problems are particularly common on older Porsche 911, 964 and 993 models.
The OE Match Collapsible CNC Alloy Oil Tube Kit, reference 93010704001, provides a practical replacement solution featuring precision-machined aluminium alloy tubes and new sealing components.
