The 2008 Legacy GT shares the EJ255 turbo engine with the WRX—fast and fun, but prone to ringland failure and head gasket weeps. The 5EAT automatic transmission is the Achilles' heel; external cooler lines crack and starve the trans of fluid, leading to catastrophic failure if ignored.
Transmission Oil Cooler Line Failure (5EAT Auto)
Common · high severity
Typical onset: 80,000-140,000 mi
Symptoms: Transmission fluid puddle under engine bay, driver's side, Low fluid warning or erratic shifting, Sudden loss of all gears if lines rupture while driving
Fix: Replace both rubber cooler lines (they rot from heat/age) and top off ATF. If caught early, trans survives. If driven low on fluid, expect internal damage requiring rebuild or replacement. 2-3 hours labor for lines only.
Estimated cost: $400-800 for lines; $2,500-4,500 if trans needs rebuild
Ringland Failure (Piston #4 Typical)
Occasional · high severity
Typical onset: 60,000-120,000 mi
Symptoms: Misfires on cylinder 4, P0304 code, Loss of compression on one cylinder, White smoke at startup or under boost, Rough idle that doesn't clear
Fix: Cast pistons crack between ring lands, usually #4 due to detonation or aggressive tunes. Requires engine removal, full teardown, forged piston set, machining, and reassembly. 25-35 hours labor depending on shop. Often done as short-block replacement.
Estimated cost: $4,500-7,500
Head Gasket Weeps (External Seepage)
Common · medium severity
Typical onset: 90,000-150,000 mi
Symptoms: Oil seepage at block/head mating surface, visible as dark streaks, Smell of burning oil after highway runs, No coolant-to-oil mixing (internal gasket failure is rare on turbo models)
Fix: Turbo EJ engines mostly seep oil externally, not coolant internally. Requires heads-off service: new gaskets, timing components, cam/crank seals while you're in there. 18-22 hours labor. Not urgent if just seeping, but will worsen.
Estimated cost: $2,200-3,200
Turbo Banjo Bolt Filter Clogging
Occasional · high severity
Symptoms: Turbo whine or screeching under boost, Loss of power, limp mode, P0025 or P0028 codes (cam correlation), Metal shavings in oil if turbo has already failed
Fix: Tiny filter screens in the turbo oil feed banjo bolts clog with debris, starving the CHRA of oil. Turbo seizes or throws blades. If caught early: clean screens, flush lines, 1 hour. If turbo is cooked: replacement required, 6-8 hours with downpipe removal.
Estimated cost: $150-300 for preventive cleaning; $1,800-2,800 for turbo replacement
Transmission Mount Failure
Common · low severity
Typical onset: 70,000-120,000 mi
Symptoms: Clunk when shifting from Park to Drive or Reverse, Excessive drivetrain movement felt through chassis, Vibration at idle in gear
Fix: Rear trans mount (pitch stop) deteriorates, allowing powertrain to rock. Easy fix: replace mount, 1-1.5 hours. OEM or aftermarket polyurethane upgrades available.
Estimated cost: $200-350
Fuel Filter Clogging / Pump Wear
Occasional · medium severity
Typical onset: 100,000+ mi
Symptoms: Hesitation or stumble under hard acceleration, Long crank times when hot, Lean fuel trims, P0171/P0174 codes
Fix: In-tank fuel pump strainer clogs or pump weakens. Drop tank, replace pump assembly or filter sock. 2-3 hours labor. Often ignored until car won't start.
Estimated cost: $400-700
Owner tips
Change transmission fluid every 30k miles and inspect cooler lines annually—this alone can save you $3,000.
Run quality 91+ octane fuel and avoid aggressive tunes on stock internals to reduce ringland risk.
Remove and clean turbo oil feed banjo bolt screens every 60k miles as preventive maintenance.
If buying used, check for oil seepage at head gaskets and ask for compression test results on all four cylinders.
Buy only with full service records and budget $2k-3k for deferred maintenance; the platform is rewarding but not for the financially unprepared.
