The 1987 Toyota Pickup is legendarily durable, but age and mileage reveal predictable weaknesses in the timing chain system, cooling components, and carburetor setups on non-fuel-injected models. Rust is the silent killer that totals more of these trucks than mechanical failures.
Timing Chain Stretch and Guide Wear (22R/22RE engines)
Common · high severityTypical onset: 150,000-250,000 mi
Symptoms: Rattling noise on cold starts that fades after 10-15 seconds, Rough idle or misfires at higher mileage, Metal shavings in oil, timing cover oil weeps, Check engine light (22RE) with timing-related codes
Fix: Replace timing chain, guides, tensioner, and rail as a complete kit. Smart to do water pump, oil pump, and front main seal while you're in there. 8-12 hours labor for experienced tech, longer for first-timers due to cramped engine bay and precision timing required.
Estimated cost: $800-1,400
Carburetor Icing and Hesitation (22R carbureted models)
Common · medium severitySymptoms: Stumbling or dying when cold, especially in humid weather, Black smoke and poor fuel economy, Hard starting when hot, Inconsistent idle speed
Fix: Professional rebuild or replacement of the Aisan carburetor. Adjustment requires experience—these are notoriously finicky. DIY rebuilds often need 2-3 iterations to get right. 3-5 hours for rebuild, 1-2 hours for replacement with reman unit.
Estimated cost: $400-800
Head Gasket Failure (22RE primarily)
Occasional · high severityTypical onset: 180,000-280,000 mi
Symptoms: White smoke from exhaust, sweet smell, Coolant loss with no visible leaks, Overheating under load, Milky oil or oil in coolant reservoir, Bubbles in radiator when running
Fix: Head gasket replacement requires head removal, resurfacing (almost always needed), and valve job. Must inspect for cracks. Check head bolts for proper torque sequence—these engines are sensitive. Always replace thermostat and radiator cap during reassembly. 12-16 hours labor.
Estimated cost: $1,200-2,200
Front Axle Vacuum Actuator and ADD System Failure (4WD models)
Common · medium severityTypical onset: 100,000-200,000 mi
Symptoms: 4WD won't engage or grinds when engaging, Hissing from front axle area, 4WD engages intermittently, Clunking from front end in 4WD
Fix: Replace vacuum actuator on front axle housing and inspect all vacuum lines (they rot and crack). Some owners convert to manual hubs for reliability. Actuator replacement is 2-3 hours; full ADD system diagnosis and repair can run 4-6 hours if chasing multiple vacuum leaks.
Estimated cost: $300-700
Frame Rust (All models, especially northern climates)
Common · high severitySymptoms: Visible rust perforation on frame rails, especially behind cab, Flaking and scaling at body mount points, Sagging bed or cab mounts, Failed state inspection due to frame integrity
Fix: Minor surface rust can be wire-brushed and treated. Structural rust requires frame sections welded in or full frame replacement—often totals the vehicle economically. Inspection is critical before purchase. Prevention with fluid film or oil undercoating adds years of life. Repair labor varies wildly: 20-60+ hours depending on severity.
Estimated cost: $2,000-8,000
EFI Cold Start Injector and Wiring (22RE)
Occasional · low severityTypical onset: 120,000-200,000 mi
Symptoms: Extended cranking when cold, Rough running first 30 seconds after cold start, Fuel smell during warmup, No issue once engine is warm
Fix: Cold start injector (CSV) fails or its thermo-time switch goes bad. Also check for corroded wiring at the injector connector—common on these. Simple replacement, 1-2 hours including diagnosis.
Estimated cost: $200-400
Clutch Master and Slave Cylinder Failure (Manual transmission)
Common · medium severityTypical onset: 100,000-180,000 mi
Symptoms: Clutch pedal goes to floor and stays there, Difficult shifting, grinding into gear, Fluid leak visible at firewall or bellhousing, Soft or spongy pedal feel
Fix: Replace both master and slave as a pair—if one goes, the other is close behind. Bleeding can be tricky due to long hydraulic line. 3-4 hours labor for both components.
Estimated cost: $350-600
Absolutely buy one if the frame is solid and timing chain has been done—these are 300k-mile trucks if rust doesn't kill them first.
