Subaru 11122AA340 — Engine Oil Pan Gasket
Overview
Engine oil pan gasket Subaru 11122AA340 seals the joint between the lower cylinder block interface and the engine oil sump pan. The component prevents engine oil leaks under high operational temperatures and internal fluid pressure, maintaining correct oil levels inside the engine crankcase. Manufactured from oil-resistant synthetic elastomer with an internal metal reinforcement core, the unit provides uniform clamping force across the entire flange mating interface. Total seal thickness measures 1.5 mm. Precise perimeter profiling aligns directly with factory Subaru sump contours, featuring 6.5 mm bolt holes engineered specifically for M6 mounting fasteners. Factory OEM reference number 11122AA340 matches original equipment specification standards across all mechanical parameters.
Replacement is required during engine overhauls, oil pan removal for oil pickup strainer inspection and cleaning, or when oil seepage appears along the lower crankcase joint. The gasket fits Subaru Forester, Impreza, Legacy, Outback, Tribeca, and XV models equipped with 2.0 L, 2.5 L, and 3.0 L petrol engines across EJ, FB, and EZ series produced between 2000 and 2020. Reusing a compressed gasket results in immediate oil loss due to material hardening and permanent compression set. This replacement gasket restores the original leak-free sealing barrier between the engine block and oil pan mating surfaces.
