- EJ25 Naturally Aspirated Head Gasket Seepage and FailureSerious
The single-overhead-cam 2.5-litre petrol boxer engine (EJ253) uses single-layer cylinder head gaskets that degrade over time and mileage. Between 80,000 and 120,000 miles, external weeping of oil and engine coolant develops at the lower block-to-head mating surfaces. If left unresolved, the breach allows combustion gases to enter the cooling jacket, causing coolant loss, overheating, warped cylinder heads, and heater matrix airlocks. Rectification requires engine removal, cylinder head skimming, and installation of upgraded multi-layer steel (MLS) head gaskets.
- Rear Suspension Lateral Link and Subframe CorrosionModerate
UK road salt and wet climates cause aggressive galvanic corrosion on the Legacy multi-link rear suspension assembly. The steel lateral links, upper wishbones, and eccentric alignment bolts seize solid inside the aluminium suspension knuckles and rear subframe bushings, making four-wheel geometry adjustment impossible. Over time, heavy corrosion can weaken the subframe crossmember and spring perches, leading to MOT failure, uneven rear tyre wear, and nervous highway stability.
