1991 TOYOTA CRESSIDA

Typical onset: 120,000-180,000 mi

Symptoms: White smoke from exhaust, Coolant loss with no visible leaks, Milky oil on dipstick, Overheating under load, Rough idle when warm

Fix: The 7M-GE is notorious for head gasket failure between cylinders 5-6 or into the coolant jacket. Requires cylinder head removal, resurfacing (usually warped 0.003-0.008 inches), new head bolts, and full gasket set. Budget 14-18 hours labor. Always check head for cracks during resurface. Replace timing belt, water pump, and all coolant hoses while you're in there.

Estimated cost: $2,200-3,500

Typical onset: 80,000-150,000 mi

Symptoms: ATF puddle under front of vehicle, Pink fluid dripping from radiator area, Transmission slipping after fluid loss, Low ATF level on dipstick

Fix: The steel cooler lines rust through where they route near the frame rail or at the crimped fittings. If you catch it early, replace just the lines (2-3 hours). If ATF contaminated the coolant or vice versa, you need a full radiator flush, new radiator, transmission flush, and possibly internal transmission damage if driven low on fluid. Many techs now run aftermarket braided cooler lines to eliminate future rust.

Estimated cost: $350-800 (lines only), $1,800-2,800 (if transmission damaged)

Typical onset: 100,000-160,000 mi

Symptoms: Severe vibration at idle, Squealing from front of engine, Visible rubber separation between hub and outer ring, Check engine light with crank position sensor codes, Accessory belt walking off pulleys

Fix: The rubber damper ring deteriorates and separates from the center hub, throwing off timing marks and accessory belt alignment. Can cause timing belt failure if the wobbling crank pulley damages the belt. Replacement requires removing the radiator fan shroud for access, 3-4 hours labor. Always inspect this during timing belt service on high-mileage Cressidas.

Estimated cost: $450-650

Typical onset: 90,000-140,000 mi

Symptoms: Clunk when shifting from Park to Drive, Excessive drivetrain vibration at idle in gear, Visible transmission sag when inspected on lift, Shifter feels loose or notchy

Fix: The rear transmission mount hydraulic fluid leaks out, causing the rubber to collapse. Creates harsh shift engagement and accelerated wear on driveshaft U-joints. Replacement requires supporting the transmission, 1.5-2 hours labor. Replace all three engine/transmission mounts if one has failed—the others are the same age and will follow soon.

Estimated cost: $280-450 (single mount), $650-900 (all three mounts)

Typical onset: 150,000-220,000 mi

Symptoms: Valve train ticking that doesn't quiet after warm-up, Low oil pressure at idle, Metal flakes in oil during changes, Loss of power at high RPM

Fix: Poor oil change intervals or running conventional oil leads to cam lobe and rocker arm wear on the 7M-GE. Requires cylinder head removal to replace camshafts, rocker arms, and shims—10-14 hours labor. Often discovered during head gasket jobs. If caught early with valve adjustment and switching to synthetic oil, can extend life, but most need full replacement by 200k miles.

Estimated cost: $1,800-2,800

Typical onset: Any mileage (age-related)

Symptoms: Hard starting when hot, Stalling after sitting in traffic, Hesitation under acceleration, Rough idle that smooths out after cooling

Fix: The in-tank fuel pump and external inline filter get clogged from rust in 30+ year old tanks. Fuel lines also deteriorate near the engine where heat causes vapor lock. Replace the inline filter every 30k miles (30 minutes labor), but most high-milers need the in-tank pump and sending unit replaced (4-5 hours including tank drop). Consider fuel tank coating or replacement if rust is severe.

Estimated cost: $150-250 (filter), $800-1,200 (pump/sender)

Typical onset: 80,000-130,000 mi

Symptoms: Clutch pedal stays on floor, Soft or spongy clutch engagement, Difficulty shifting into first or reverse, Fluid leak at master or slave cylinder

Fix: The clutch master and slave cylinders leak internally or externally on manual cars. Master is easier at 2 hours labor, slave requires transmission removal or access from underneath. If doing a clutch job, replace both hydraulic components, the clutch kit, pilot bearing, and resurface the flywheel—it's 8-10 hours with transmission out anyway.

Estimated cost: $300-500 (hydraulics only), $1,400-2,000 (full clutch job)
