1995 TOYOTA SUPRA

Typical onset: 60,000-100,000 mi

Symptoms: white smoke from exhaust on cold start, coolant disappearing without external leaks, bubbles in radiator or overflow tank, milky oil on dipstick or cap, rough idle when warm

Fix: Factory head gaskets fail due to inadequate torque spec and poor gasket design. Requires complete head removal, resurfacing both heads, ARP studs, and MLS gaskets. 18-24 labor hours including coolant system flush and timing belt replacement while you're in there.

Estimated cost: $3,500-5,500

Typical onset: 80,000-140,000 mi

Symptoms: transmission slipping or delayed engagement, strawberry milkshake appearance in radiator, coolant in transmission pan, sudden transmission failure after overheating, coolant level dropping

Fix: Internal radiator transmission cooler fails and cross-contaminates coolant into ATF, destroying the transmission within days. Requires radiator replacement, transmission rebuild or replacement, complete fluid flush of both systems. If caught early (just cooler leaking), 4-6 hours. If transmission damaged, add 12-16 hours for rebuild. This is a design flaw—install external cooler and bypass radiator cooler as preventive.

Estimated cost: $800-1,200 (cooler only), $3,500-5,000 (with trans rebuild)

Symptoms: blue smoke on acceleration, loud whining or grinding from engine bay, significant loss of boost pressure, oil leaking from turbo seals, metal shavings in intake piping

Fix: Sequential turbos fail from aftermarket boost controllers, poor oil changes, or hard launches without proper warmup. OEM turbos are NLA; expect upgraded aftermarket singles or rebuilt CT12s. 10-14 labor hours including oil feed/return lines, gaskets, and downpipe work.

Estimated cost: $2,000-4,500

Typical onset: 100,000-150,000 mi

Symptoms: stumbling or hesitation under hard acceleration, won't start when fuel tank below 1/4, whining noise from rear of car, loss of power above 4,000 RPM, check engine light with fuel trim codes

Fix: In-tank pump wears out, especially on turbo models running higher fuel demands. Drop tank, replace pump and strainer, replace old fuel hoses. 3-4 labor hours. Turbo cars often get upgraded Walbro 255 pumps.

Estimated cost: $600-900

Typical onset: 80,000-120,000 mi

Symptoms: clunk when shifting from reverse to drive, clunk on throttle lift-off, vibration at highway speeds, visible movement in differential when rocking car

Fix: Differential carrier bushings deteriorate, causing slop and drivetrain lash. Requires removing differential, pressing out old bushings, installing polyurethane or OEM replacements. 4-6 labor hours. Many owners go poly for longevity.

Estimated cost: $500-800

Typical onset: all mileages

Symptoms: window moves slowly or binds, clicking noise from door when operating window, window drops into door, window won't move at all

Fix: Plastic regulator tracks crack, motors burn out. Door panel removal and regulator replacement. 2-3 hours per side. OEM parts are expensive and NLA; aftermarket quality varies.

Estimated cost: $400-700 per door

Symptoms: water dripping on passenger head or center console, wet carpet after rain or car wash, wind noise at highway speeds, visible light gaps around targa seal

Fix: Rubber seals harden and shrink over 30 years. Replacement seals available but require careful installation and adjustment of latch tension. 1-2 hours labor, but achieving perfect seal can be tedious.

Estimated cost: $300-500
