On the 1996-1999 Subaru Legacy, the DOHC EJ25 and the 1997-and-later SOHC EJ boxers are interference designs - if the rubber timing belt breaks or jumps teeth, the pistons strike open valves and bend them, often ruining the heads. (The pre-1997 SOHC EJ22 is non-interference; the change to interference on the SOHC came in 1997.) Because these are now 25+ year-old cars, an original or overdue belt is a real risk. Subaru's interval on the later EJ engines is 105,000 miles / 105 months, but age alone degrades the belt, tensioner and idlers.

Common Symptoms

  • Engine cranks but will not start after belt snaps
  • Sudden stall with rough compression afterward
  • Ticking/whirring from front timing cover (failing idler/tensioner)
  • Original or unknown-age timing belt at high mileage

How to Fix

Replace the timing belt on schedule (105k/roughly 7 years) together with the tensioner, idler pulleys, water pump and seals as a kit. If a belt has already failed on an interference engine, expect a valve job or head/engine replacement.

On the 1996-1999 Subaru Legacy EJ25D 2.5L DOHC (Phase I), the first 2.5L boxer in the Legacy, the EJ25D DOHC (Phase I), used a composite head gasket that fails internally around the 100,000-mile mark. Unlike the later external-leak variant, this failure lets coolant and combustion gases mix, causing loss of compression, coolant in the oil (milky oil), or combustion gases pressurizing the cooling system. Subaru dropped the DOHC 2.5 configuration after 1999 largely because of this. It is the single most notorious mechanical problem on the 2.5L cars of this era.

Common Symptoms

  • Overheating
  • Coolant loss with no obvious external leak
  • Milky/creamy oil on dipstick or oil cap
  • Bubbling/pressurized coolant overflow tank
  • White exhaust smoke
  • Loss of engine compression/rough running

How to Fix

Replace both head gaskets with the updated multi-layer steel (MLS) design, resurface both heads, and replace the timing belt, water pump, thermostat and coolant while the engine is apart.

On the 1990-1999 Subaru Legacy, automatic-transmission Legacys use an electronically controlled transfer clutch (governed by the Duty C solenoid) to send torque to the rear wheels. When the clutch pack sticks engaged or the Duty C solenoid gets dirty/sticky, the AWD stays locked on dry pavement and cannot relieve driveline wind-up, producing 'torque bind' - juddering and hopping during slow, tight turns. Mismatched tire diameters accelerate the wear.

Common Symptoms

  • Shudder/hop/binding in tight low-speed turns
  • Driveline lurch when parking or making U-turns
  • Symptom disappears with the FWD fuse installed
  • Worse when cornering, absent on straight dry road

How to Fix

Confirm the fault by inserting the under-hood FWD fuse - if the binding disappears, the transfer clutch is the cause. Fixes range from cleaning/replacing the Duty C solenoid and servicing the fluid to rebuilding the transfer/tail section. Always run four matched tires to prevent recurrence.

On the 1990-1999 Subaru Legacy, the Legacy's front hubs use tapered roller bearings that require correct axle-nut preload. On these cars they are a common wear item: an improperly torqued axle nut, high mileage, or water intrusion leads to a growing hum/roar that rises with road speed and changes when loading the bearing in a turn. Left unaddressed the bearing can develop play and damage the hub.

Common Symptoms

  • Humming/roaring that increases with speed
  • Noise changes pitch/volume when turning left vs right
  • Growling from one front corner
  • Play/wobble felt at the wheel when rocked

How to Fix

Replace the worn wheel bearing (press-in on this generation), set the axle-nut preload to spec, and inspect the opposite side. Confirm the noisy side with a sway/turn test - noise that grows when weight shifts to one side points to that bearing.
