What This Part Does / Functions
• Seals the oil pump / tandem pump connection
• Helps prevent engine oil leakage
• Supports correct sealing within the lubrication system

Why Replace This Part?
O-ring seals are exposed to engine oil, heat, pressure and age-related hardening. Over time, the seal can flatten, crack, swell or lose elasticity. Once the pump assembly has been removed or disturbed, the seal should normally be replaced to ensure a reliable seal when reassembled. Replacing it with a Genuine Porsche OE oil pump / tandem pump seal helps prevent oil leaks and supports correct engine lubrication system sealing.
Common Symptoms of a Failed Oil Pump / Tandem Pump Seal
• Engine oil leak around the oil pump / tandem pump area
• Oil residue near the pump housing
• Persistent seepage after previous engine work
• Hardened, flattened or cracked O-ring during inspection
• Oil smell from hot engine components
• Oil drips underneath the vehicle
• Seal damage after pump removal
• Need to reseal the pump during engine service.
When to Replace This Part
When removing or refitting the oil pump / tandem pump. During engine oil pump service or replacement. If oil leakage is traced to the pump seal area. If the O-ring is hardened, flattened, cracked or damaged. During engine rebuild or lubrication system repairs. When replacing related pump components. After separating the pump from its sealing surface. Whenever Porsche workshop procedure recommends replacing the seal after removal.
Where It Fits on the Car
This O-ring fits in the engine oil pump / tandem pump assembly. It seals the pump connection point and helps prevent oil from leaking at the pump housing. Correct installation is important. The sealing surface should be clean, and the O-ring should be fitted without twisting, pinching or damage.
