Parts for your 2012 Subaru Impreza-Oil seals

2012 Subaru Impreza oil seals

Oil seals are absolutely fitted to the 2012 Subaru Impreza. Subaru’s factory service manuals for the 2012 model (FB20 engine and TR580 Lineartronic CVT/5‑speed manual) and the Subaru parts catalogue both show multiple radial shaft oil seals used throughout the powertrain. These include the front (crank pulley end) and rear main crankshaft seals, camshaft seals, gearbox input and output seals, and differential/axle shaft seals. These sources confirm oil seals are relevant components that keep engine oil and transmission fluid where they belong and protect bearings and friction surfaces.

On this Impreza, oil seals do the heavy lifting of containing lubricants while shafts spin at high speed. The front crank seal prevents engine oil from escaping behind the harmonic balancer. The rear main seal keeps oil inside at the flywheel/flexplate end. Camshaft seals live at the ends of the cams behind the timing covers. In the driveline, the CVT or manual gearbox uses input and output shaft seals, and both the transaxle and rear differential rely on axle oil seals. When these go brittle or wear grooves in the mating surface, leaks start.

They’re not a routine “every X kilometres” replacement. Instead, they’re replaced when signs of leakage appear or proactively when access is easy (for example, with the timing covers off for chain/tensioner work, or when the gearbox is out). Genuine or OE‑quality seals are worth it
