1999 TOYOTA MARK II

Typical onset: 120,000-180,000 mi

Symptoms: Harsh 2-3 shift or slipping, Delayed engagement when cold, Whining noise from torque converter, Burnt ATF smell

Fix: Toyota A340 series has weak direct clutch drums and worn valve bodies. Rebuild requires 12-16 hours, replacement/rebuild of clutch packs, bands, and often the torque converter. Many opt for used JDM replacement (8 hours swap) but condition is unknown. Prevention: fluid changes every 30k miles religiously.

Estimated cost: $2,800-4,500

Typical onset: 150,000-200,000 mi

Symptoms: Rattling from timing cover on cold starts, P1349 or P1346 codes, Loss of low-end torque, Check engine light

Fix: VVT-i cam gear internal actuator seizes or oil control valve fails. Requires timing cover removal, cam gear replacement (OEM ~$400 part). 6-8 hours labor. Often catches people off-guard because engine otherwise runs fine. Use quality oil and change every 5k miles to delay this.

Estimated cost: $1,200-1,800

Typical onset: 100,000-150,000 mi

Symptoms: Clunking over bumps, Wandering steering, Inner tire wear, Play in wheel when jacked up

Fix: Front suspension uses pressed-in bushings that crack and separate with age. Ball joints develop play. Most replace entire lower control arms ($150-250 each side with bushings installed) rather than pressing. 4-5 hours both sides including alignment. Do both sides simultaneously.

Estimated cost: $800-1,200

Typical onset: 130,000-180,000 mi

Symptoms: Blue smoke on deceleration, Excessive shaft play, Whistling or grinding noise under boost, Oil consumption increase

Fix: CT12/CT15 turbos (1JZ-GTE) or sequential turbos (2JZ-GTE) fail from oil coking or bearing wear. Single turbo 1JZ rebuild/replacement: 8-10 hours. Twin-turbo 2JZ-GTE is nightmare access (14-18 hours) due to sequential setup. Many upgrade to single aftermarket turbo on 2JZ. Catch it early before shaft scores the housings.

Estimated cost: $2,000-5,500

Typical onset: 120,000+ mi

Symptoms: PS fluid puddles under engine, Whining when turning, Stiff steering when cold, Fluid on alternator/accessories

Fix: High-pressure hose from pump to rack develops pinhole leaks or end fittings weep. Pump itself can leak from shaft seal. Hose replacement is 2 hours, pump is 3 hours. Leaking fluid often drips onto alternator causing secondary failure. Address immediately when spotted.

Estimated cost: $400-900

Symptoms: Misfire codes P0300-P0306, Rough idle, Hesitation under load, Poor fuel economy

Fix: 1JZ uses three coil packs (wasted spark design, each fires two cylinders). They crack internally or develop carbon tracking. Misfires often intermittent and worse in wet weather. Replace all three at once (~$300 in aftermarket coils), 1.5 hours. OEM coils are $150+ each but last longer.

Estimated cost: $400-700

Typical onset: 180,000+ mi

Symptoms: Blue smoke on startup, Burning 1 quart per 1,000 miles, Fouled spark plugs, Oil smell from exhaust

Fix: High-mileage 1JZ/2JZ develop oil consumption from hardened valve seals or worn rings. Valve seals: 10-12 hours (heads off). Full rings require disassembly (40+ hours if doing proper hone/measure). Many just monitor oil and top off if consumption is under 1qt/1000mi. These engines tolerate it surprisingly well.

Estimated cost: $1,500-2,800
