The 1976 Plymouth Fury is a full-size C-body Mopar with robust LA and B-series V8s (or the slant-six). Most issues stem from age rather than inherent design flaws—expect rubber, linkages, and emission controls to be worn after nearly 50 years.
Timing Chain Stretch and Wear (V8 engines)
Common · high severityTypical onset: 80,000-150,000 mi
Symptoms: rattling on cold start that quiets after warmup, rough idle or erratic timing, backfiring through carburetor, difficulty starting when hot
Fix: Replace timing chain, gears, and tensioner as a set. Plan 4-6 hours labor for front cover removal, gasket replacement, and timing adjustment. Non-interference engine, so usually no valve damage, but delay leads to jumped timing and no-start.
Estimated cost: $400-800
Lean Burn Ignition System Failures (California and late '76 models)
Common · medium severitySymptoms: intermittent stalling or no-start, bucking and surging under light throttle, check engine light (if equipped), poor fuel economy and hesitation
Fix: The computer control module and pickup coil in distributor are notorious. Most techs convert to conventional electronic ignition (Mopar Performance kit or pre-'76 distributor swap). Troubleshooting original system is frustrating. Conversion takes 2-3 hours.
Estimated cost: $200-500
Carburetor Issues (Carter ThermoQuad and Holley 2-bbl)
Common · medium severitySymptoms: flooding and fuel leaks from warped phenolic body (ThermoQuad), hard starting when warm, black smoke and rich running, hesitation off idle
Fix: ThermoQuad plastic bodies warp with age and heat—many swap to Edelbrock or Holley replacement. Holley 2-bbl needs periodic rebuild. Full rebuild or replacement takes 2-4 hours including tuning.
Estimated cost: $300-700
Torsion Bar Suspension Sag and Worn Bushings
Common · low severityTypical onset: 60,000-100,000 mi
Symptoms: front end sits low, headlights point upward, wandering and vague steering, clunking over bumps, uneven tire wear
Fix: Torsion bars rarely break but adjusters seize and lower control arm bushings disintegrate. Full front-end refresh (bushings, ball joints, adjuster service) runs 6-8 hours. Alignment mandatory afterward.
Estimated cost: $600-1,200
Transmission Kickdown Linkage Misadjustment (TorqueFlite A727/A904)
Occasional · medium severitySymptoms: delayed or no downshift on WOT, trans slipping or flaring between gears, late upshifts and lugging, burnt transmission fluid smell
Fix: Kickdown rod or cable comes out of adjustment or wears. Simple adjustment takes 0.5 hours, but delayed diagnosis leads to clutch/band damage requiring trans rebuild (10-15 hours). Check and adjust every service.
Estimated cost: $50-150 adjustment, $1,500-2,500 rebuild if damaged
Fuel Tank and Sending Unit Corrosion
Occasional · medium severitySymptoms: inaccurate or stuck fuel gauge, fuel leaks from tank seams, rust flakes in fuel filter, fuel pump starvation
Fix: Steel tanks rust through after decades, especially if stored outdoors. Sending units seize. Tank drop and replacement takes 3-4 hours; sending unit alone 2 hours. Many upgrade to aftermarket poly tank.
Estimated cost: $400-900
Power Steering Gear Box Leaks and Slop
Occasional · low severityTypical onset: 80,000-120,000 mi
Symptoms: power steering fluid leaks at sector shaft seal, excessive play at center (more than 2 inches wheel movement), groaning when turning, wandering on highway
Fix: Chrysler recirculating-ball boxes develop sector shaft seal leaks and internal wear. Adjustment helps temporarily (0.5 hours), but rebuilt/reman box swap is long-term fix (3-4 hours). Alignment needed.
Estimated cost: $300-700
Buy one if you're comfortable with carburetors and can wrench—parts are cheap, engines are stout, but 50-year-old emissions and ignition tech will test your patience.
