Subaru 10991AA001 — Engine Oil Pump Seal

Overview

Oil pump O-ring Subaru 10991AA001 seals the oil passage junction between the oil pump housing and the engine block. Manufactured from heat-resistant fluororubber (FKM), it withstands direct exposure to engine oil, fluid additives, and operational temperatures up to 150 °C. Key dimensions feature an inner diameter of 12.5 mm and a cross-section thickness of 2.2 mm. OEM part number 10991AA001 matches exact original equipment specifications. This seal prevents air suction on the oil pump inlet side, maintaining correct oil pressure across internal galleries and stopping oil seepage at high engine operating speeds. Rubber compound retains flexibility under severe thermal cycling and resists compression set.

Fitment includes Subaru Forester (1997–2018), Impreza (1992–2016), Legacy (1989–2019), Outback (1998–2019), and XV (2011–2017) models fitted with EJ15, EJ18, EJ20, EJ22, EJ25, FB20, and FB25 engine variants. Standard maintenance schedule dictates replacement of this O-ring during major engine overhauls, oil pump servicing, timing belt or chain replacement, or when oil leaks are identified around the front main crankshaft seal area. Replacing the hardened seal during pump removal restores oil channel pressure and stops front engine cover contamination.
