1998 TOYOTA MR2

Typical onset: 80,000-140,000 mi

Symptoms: white smoke from exhaust on cold start, coolant loss with no visible leaks, milky oil on dipstick or oil cap, overheating under boost, rough idle when warm

Fix: Factory head gasket design is weak and fails between cylinders 2-3. Requires engine-out service in most cases due to mid-engine layout and tight firewall clearance. 18-24 hours labor for removal, machine work, ARP studs, MLS gasket, timing belt/water pump while apart, reinstall and tune. Many shops refuse this job due to access issues.

Estimated cost: $3,500-6,000

Typical onset: 60,000-120,000 mi

Symptoms: rear end feels loose or darty over bumps, sudden oversteer mid-corner with throttle lift, clunking from rear suspension, uneven rear tire wear

Fix: The SW20 is infamous for lift-off oversteer due to mid-engine weight bias and rear suspension geometry. Worn trailing arm bushings make this worse. Replacement requires pressing out old bushings and installing polyurethane or OEM rubber. 4-6 hours labor for both sides. Critical safety item—fresh bushings and proper alignment are mandatory before spirited driving.

Estimated cost: $600-1,200

Symptoms: transmission fluid weeping from firewall area, low fluid level on dipstick, burnt smell from engine bay, difficulty shifting when hot

Fix: Steel hardlines running to the transmission cooler rust through at fittings and flex joints, especially in salt states. Lines are NLA from Toyota; most shops fabricate custom stainless or aluminum replacements. 3-5 hours labor depending on turbo vs NA (turbo has less access). Flush transmission after repair.

Estimated cost: $500-900

Typical onset: 70,000-110,000 mi

Symptoms: heavy clunk when shifting or engaging clutch, excessive engine movement visible from cabin, vibration at idle, difficulty getting into gear

Fix: Rubber mounts deteriorate and the mid-engine layout amplifies movement. Rear transmission mount is worst and requires lifting the subframe. Front engine mount is easier. Budget 3-4 hours for front mount, 5-7 hours for rear mount due to exhaust removal and subframe drop. Replace both at same time if possible.

Estimated cost: $800-1,400

Symptoms: fuel smell in cabin or trunk, check engine light with evap codes P0440/P0441, visible corrosion on tank straps, fuel gauge erratic

Fix: Fuel tank is steel and rusts from topside where road salt accumulates. Evap canister and lines also corrode. Tank replacement requires dropping rear subframe and suspension—extremely labor intensive. 10-14 hours labor. Many owners opt for aftermarket aluminum tanks or used OEM from dry-climate cars.

Estimated cost: $1,800-3,000

Symptoms: water pooling in footwells after rain, musty smell in cabin, fogged windows that won't clear, water stains on headliner

Fix: T-top seals and window channel felts harden with age. Water intrudes and drains into cabin, causing rust in floor pans and ECU area (ECU is under passenger carpet). T-top seals are available aftermarket; window felts require door panel removal. 2-3 hours labor per side for window felts, 1 hour for T-top seals. Preventive replacement recommended.

Estimated cost: $400-800

Typical onset: 100,000-150,000 mi

Symptoms: blue smoke on acceleration, loud whistle or grinding from turbo, loss of boost pressure, oil consumption increases, check engine light with low boost codes

Fix: CT26 turbo is reliable but eventually fails from shaft play or oil starvation. Replacement requires removing intercooler piping, downpipe, and heat shields. 8-12 hours labor. OEM turbos are NLA; most use rebuilt CT26 or upgrade to aftermarket. Oil feed and return lines should be replaced simultaneously.

Estimated cost: $1,500-3,000
