Oil Pump Pickup Pipe Aluminum FKM Seal for Vauxhall Insignia

Upgrade your Opel/Vauxhall 2.0 CDTI engine with the Oil Pump Pickup Pipe Aluminum FKM Seal. This precision sleeve-gasket replaces the defective OE seal between the oil pump and the pickup pipe, delivering a robust, permanent connection that preserves oil flow and lubrication pressure. Unlike some other versions, this design does not reduce the cross-section of the oil flow, helping prevent oil leaks and potential engine damage.

The kit features an aluminum sleeve that connects the oil pump to the pickup pipe and uses high-temperature, oil-resistant FKM O-rings to ensure a tight seal. Over time OE gaskets can harden and leak, leading to dropped lubrication pressure and costly engine problems. This sleeve-seal addresses that defect, offering a durable solution that stays resin-stable under engine heat and oil exposure. The corrected part has been used in 2.0 CDTI engines such as the B20DTH (LFS) 170 KM with AdBlue, and carries OE references 55589549 and 646125.

Compatibility covers a wide range of vehicles and engine variants, including:

• Opel/Vauxhall Insignia A (2009-2017)
• Opel/Vauxhall Cascada (2013-2018)
• Opel/Vauxhall Astra J (2009-2015)
• Opel/Vauxhall Zafira C (2012-2018)
• 2.0 CDTI engines with codes A20DTC/A20DTL, A20DTJ/A20DT, A20DTE, A20DTH, A20DTR (various outputs)
• Chevrolet Malibu (V300) 2.0D LBS
• Suzuki SX4 (EY/GY) 1.6 DDiS and 2.0 DDiS variants
• Suzuki Vitara (LY) 1.6 DDiS
• Saab 9-5 (YS3G) 2.0 TTiD, Saab 9-3 (YS3F) 1.9 TTiD

The set contains: 1 x sleeve-gasket (aluminum); 2 x FKM O-rings sealing the sleeve; 1 x FKM O-ring sealing the oil level sensor plug; 2 x FKM O-rings sealing the crankcase breather inside the oil pan; 1 x FKM O-ring sealing the crankcase breather vent outside the oil pan.

The replacement process is straightforward: remove the old gasket and install the aluminum sleeve-gasket in its place. This solution directly addresses the common OE gasket failure that can lead to oil leaks and reduced lubrication pressure, helping to prevent engine malfunction.

Origin: Mainland China. OE / OEM reference numbers: 55589549, 646125. Opposite to other versions (not bolted), this design maintains oil flow without cross-section restriction, ensuring consistent lubrication during operation.

Benefits & Tips

• Helps prevent oil leaks at the oil pump pickup connection, maintaining steady lubrication pressure and reducing the risk of engine damage.
• Simple swap: remove the old gasket and install the aluminum sleeve with FKM O-rings for a durable seal.
• Using FKM O-rings provides strong resistance to high temperatures and oil exposure, boosting long-term reliability.
