Oil Pump Pickup Tube Aluminum With FKM Seal For Vauxhall Opel Insignia

This aluminum oil pump pickup tube sleeve replaces the factory composite gasket on multiple GM-derived diesel engines to stop slow leaks and maintain steady lubrication pressure. Original equipment seals frequently harden or deform under repeated heat cycles, allowing oil to bypass the connection point and trigger dashboard low-pressure warnings. The machined aluminum body resists deformation while the accompanying FKM O-rings withstand continuous exposure to hot motor oil. Installation follows standard bolt-on procedures: remove the existing assembly, clean the mating flanges, and secure the new sleeve with the provided hardware.

Benefits & Tips

Corrects the documented sealing defect on A20DTH and related 2.0-liter diesel blocks where stock gaskets fail due to material fatigue. Match your engine casting stamp or chassis documentation to the verified codes before purchase, as oil pan geometry varies across production runs. During assembly, apply copper anti-seize only to the pickup tube stud threads, and always replace the primary oil pan gasket to avoid cross-contamination. Verify steady oil pressure readings after the initial five-minute warm-up cycle before returning the vehicle to regular service.

Warnings & Service Reminders

Always drain, flush, and refill fresh engine oil after reassembling the pickup tube circuit to remove residual particulate matter. Inspect the manifold junction for fluid weeping during the first drive cycle, and retoric mounting fasteners only when the engine block reaches normal operating temperature.
