The ST205 and ST185 generations (1990-1999) are generally reliable Toyotas, but the naturally-aspirated 5S-FE 2.2L suffers oil consumption from worn rings, while the 3S-GTE turbo models face head gasket failures and overboosting issues when modified or neglected.
Head Gasket Failure (2.2L 5S-FE)
Common · medium severityTypical onset: 120,000-180,000 mi
Symptoms: white smoke from exhaust on cold start, coolant loss with no visible leak, milky oil on dipstick or cap, overheating under load
Fix: Head gasket replacement requires removing timing belt, cam gears, and resurfacing the head if warped. Timing belt and water pump should be replaced simultaneously. Budget 8-10 hours labor plus machining.
Estimated cost: $1,200-1,800
Oil Consumption (2.2L 5S-FE)
Common · low severityTypical onset: 150,000+ mi
Symptoms: burning 1 quart per 1,000 miles or worse, blue smoke on deceleration or startup, fouled spark plugs
Fix: Worn piston rings are the culprit—no real fix short of engine rebuild or replacement. Rebuild involves full teardown, honing cylinders, new rings, bearings, seals. 18-24 hours labor.
Estimated cost: $2,500-4,000
Head Gasket Failure (2.0L 3S-GTE Turbo)
Occasional · high severityTypical onset: 80,000-120,000 mi
Symptoms: coolant pressurizing and blowing out overflow, white smoke under boost, overheating after spirited driving, combustion gases in coolant (bubbles in reservoir)
Fix: Factory head gasket is marginal—boost creep or tuning accelerates failure. Requires head removal, ARP studs recommended, head resurfacing. Expect 10-12 hours labor. Many owners upgrade to MLS gasket during repair.
Estimated cost: $1,800-2,800
Transmission Oil Cooler Line Leaks (Auto)
Common · medium severityTypical onset: 100,000-150,000 mi
Symptoms: ATF puddles under front of car, transmission overheating, burnt smell from trans fluid, slipping shifts when hot
Fix: Steel lines rust at fittings and connections to radiator-mounted cooler. Replacement lines or external cooler install. 2-3 hours labor including fluid refill.
Estimated cost: $300-600
Worn Transmission Mounts
Common · low severityTypical onset: 100,000+ mi
Symptoms: clunking on acceleration or deceleration, excessive shifter vibration, engine rocking visible from engine bay
Fix: Rubber mounts deteriorate—front and rear mounts most common. Straightforward replacement, 1.5-2 hours labor for both.
Estimated cost: $200-400
Turbo Wastegate Sticking (3S-GTE)
Occasional · medium severitySymptoms: boost spiking over 12-14 psi, erratic boost gauge readings, limp mode or knock sensor intervention, wastegate rattle at idle
Fix: Carbon buildup or actuator diaphragm failure causes overboosting, risking engine damage. Turbo removal and wastegate actuator replacement or cleaning required. 4-6 hours labor.
Estimated cost: $500-1,200
Camshaft Position Sensor Failure
Occasional · medium severityTypical onset: 120,000+ mi
Symptoms: no-start or crank-no-start, intermittent stalling, rough idle or surging, check engine light with cam sensor code
Fix: Sensor located behind timing belt cover on some models. Requires timing cover removal if not externally accessible. 1.5-2.5 hours labor depending on access.
Estimated cost: $200-450
Buy a manual-trans non-turbo example under 120k miles for reliable transport; avoid high-mileage 5S-FE or modified 3S-GTE unless you're ready for engine work.
