Common Subaru Engine Issues
These are the most frequent reasons Subaru owners need a replacement engine.
EJ25 2.5L SOHC (1999–2012 Outback/Forester/Impreza) — Head Gasket Failure: This is THE Subaru engine replacement story. The EJ251 and EJ253 SOHC boxer engines develop external head gasket leaks that weep oil and coolant between the cylinder heads and block. The leak worsens over time and can eventually cause overheating and internal coolant contamination. The head gasket repair requires pulling the engine from the car (unique to the boxer layout), and at that labor cost, a replacement engine with new gaskets is often the smarter investment. This is our single highest-volume Subaru engine.
FB25 2.5L DOHC (2012+ Outback/Forester/Crosstrek) — Excessive Oil Consumption: The FB25 (2012–2016 specifically) develops piston ring issues that cause oil consumption exceeding 1 quart per 3,000 miles. Subaru issued a TSB (02-157-14R) and extended warranty for some models, but many are now out of coverage. Replacement is the definitive fix.
EJ255/EJ257 Turbo (WRX/STI) — Rod Bearing & Ringland Failure: The turbo EJ25 is notorious for two failure modes. Rod bearings spin due to oil starvation at the #4 cylinder (the hottest in the boxer layout), and ringlands crack under boost — particularly on tuned or modified engines. Stock engines with strict oil maintenance are more durable, but these are still high-failure-rate engines that drive constant replacement demand.
FA20F 2.0L Turbo (WRX 2015–2021) — Improved Over EJ: The FA20 turbo resolved many EJ25 issues with a direct-injection design and better oiling. However, it can develop spun rod bearings at stock boost levels if oil maintenance is neglected. Significantly more reliable than the EJ25 turbo when properly maintained. When rod bearing failure does occur, a replacement FA20F with verified oil change history is the reliable path forward — far more predictable than attempting to rebuild a damaged bottom end.

Subaru Engine — Quick Answers
Why do Subaru head gaskets fail?
The EJ25 SOHC boxer uses a multi-layer steel head gasket at a horizontal orientation where coolant and oil can pool at the gasket mating surface. Over time, the gasket seal degrades and begins weeping externally. This is an age and mileage-related issue, not a sudden failure. Our replacement engines are sourced with verified gasket integrity.
Is the Subaru FB25 better than the EJ25?
The FB25 resolved the external head gasket leak issue but introduced oil consumption concerns on 2012-2016 models. Post-2016 FB25 revisions improved ring design significantly. Both are fundamentally reliable boxer engines — the specific failure mode simply changed between generations.
Do you carry Subaru WRX STI engines?
Yes — we stock the EJ257 2.5L turbo for the STI and the FA20F 2.0L turbo for the WRX. Due to extremely high demand and limited supply of low-mileage units, we recommend quoting immediately.
Does the Subaru engine come with the turbo?
Yes — turbo applications ship with the turbocharger assembly, exhaust manifold, and intercooler piping attached. Naturally aspirated boxers ship as complete long blocks.
