Parts for your 2014 Subaru Exiga-Oil pump

2014 Subaru Exiga oil pump — what it does and when to service it

Yes, the 2014 Subaru Exiga is fitted with an engine oil pump. Subaru’s factory service material for the Exiga YA chassis lists an oil pump in the Engine Lubrication (LU) section, with full removal, inspection and installation procedures. The EJ-series engines commonly fitted to the Exiga in 2014 use a crankshaft-driven, front-mounted gerotor pump behind the timing belt pulley. Later-market variants using FB-series engines retain an internal oil pump integrated with the front cover. Technical references: Subaru Exiga YA Service Manual (Engine—Lubrication: Oil Pump), Subaru EJ Engine FSM (LU section), and Subaru FB25 FSM (Engine Lubrication—Oil Pump).

On this model, the oil pump’s job is to pull oil from the sump and push it under pressure through the filter and galleries to bearings, camshafts, and the turbo (if equipped). Proper pressure is what keeps the Exiga happy on long Kiwi and Aussie road trips—without it, bearings cop a hiding, timing components wear, and the engine can go from sweet to sour in a heartbeat.

As part of regular servicing, clean oil is the first line of defence. Sticking to 10,000–12,500 km (or 6-month) oil and filter intervals with the correct grade noted on the oil cap/owner’s manual (typically 5W-30 for many EJ applications, and 0W-20 for some FB variants) helps the pump maintain stable pressure. It’s also smart to keep an eye on any oil pressure warning lamp behaviour and unusual top-end ticking or bottom-end rumble.

Oil pumps aren’t a routine replacement item, but there are times to pay them extra attention:

• EJ engines: during timing belt service (around 100,000–105,000 km), inspect the pump, front crank seal and backing plate screws, and replace the pump O-ring. Many Subaru techs re-torque and apply threadlocker to backing plate screws if removed.
• FB engines: the pump is within the front cover
