Subaru 13271AA071 — Valve Cover Bolt Grommet
Overview
Valve cover bolt seal Subaru 13271AA071 seals the rocker cover mounting bolts against crankcase oil pressure. Constructed from oil-resistant nitrile butadiene rubber (NBR) bonded to a rigid steel washer core, it withstands thermal cycles from -40 °C to +150 °C. Key technical dimensions include an inner diameter of 6.5 mm, an outer diameter of 20 mm, and an overall height of 7.5 mm. OEM part number reference is 13271AA071, superseding previous manufacturer part number 13271AA070. The elastomeric element prevents fluid leakage past bolt threads and down into cylinder head spark plug tubes under operational pressure.
Fits Subaru Forester (SF, SG, SH chassis) 1997–2010, Impreza (GC, GD, GG chassis) 1998–2007, and Legacy/Outback (BE, BH, BL, BP chassis) 1998–2009 equipped with 1.6, 2.0, 2.2, and 2.5 litre EJ series boxer petrol engines (including EJ16, EJ20, EJ22, and EJ25 variants). Replacement becomes necessary when the rubber hardens, cracks, flattens, or loses elasticity from thermal stress, resulting in fluid weeping around cylinder head covers. New bolt seals must be fitted whenever removing rocker covers for valve clearance adjustments, camshaft inspections, or timing belt system maintenance work.
