1979 FSO POLONEZ

Typical onset: 60,000-90,000 mi

Symptoms: Loud ticking/tapping from valve cover at startup that persists when warm, Loss of power and rough idle, Eventually progresses to bent pushrods if ignored

Fix: The Fiat 1600 engine uses hydraulic lifters that fail frequently due to oil quality issues and age. Full lifter replacement requires 4-6 hours labor, often reveals camshaft lobe wear requiring cam replacement (add 3-4 hours). Many techs recommend doing cam and all lifters together since you're already in there.

Estimated cost: $800-1,800

Typical onset: 50,000-80,000 mi

Symptoms: Severe clunking when shifting or engaging clutch, Excessive driveline vibration, Visible transmission sag when inspected on lift, Difficulty getting into gear

Fix: Original rubber mounts are four decades old and turn to mush. The transmission literally drops and misaligns the shifter linkage. Replacement is straightforward but requires supporting the transmission - 2-3 hours labor. NOS or aftermarket mounts can be difficult to source.

Estimated cost: $300-600

Typical onset: 70,000-120,000 mi

Symptoms: White smoke from exhaust, Coolant loss with no visible leaks, Milky oil on dipstick, Overheating especially in traffic

Fix: The Fiat 1600 head gasket fails when cooling system neglect causes overheating. Job requires 8-12 hours including head removal, resurfacing (usually warped), and reassembly. Head resurface adds $150-250 at machine shop. Often find corroded coolant passages requiring extensive cleaning.

Estimated cost: $1,200-2,200

Symptoms: Transmission fluid puddles under car, Burnt smell from dripping fluid on exhaust, Low fluid causes slipping or delayed engagement

Fix: Steel cooler lines rust through where they route near the exhaust and frame rails. Leaks can drain the transmission quickly leading to catastrophic failure. Line replacement is 2-3 hours but finding correct fittings is the real challenge - often requires custom fabrication. Check fluid level religiously on these cars.

Estimated cost: $400-800

Typical onset: 80,000-140,000 mi

Symptoms: Severe vibration at idle that worsens with RPM, Visible wobble of crankshaft pulley, Squealing belts that keep loosening, Eventually throws belt and causes overheating

Fix: The rubber ring between inner hub and outer ring deteriorates and separates, causing the pulley to wobble. If it comes apart completely at speed, it can damage the front cover and crankshaft nose. Replacement is 2-3 hours but requires special puller and installer tools. Do not ignore this one.

Estimated cost: $350-650

Symptoms: Hesitation and stumbling under acceleration, Hard starting when hot, Stalling at idle, Loss of power at highway speeds

Fix: These cars often sit for extended periods, and old fuel varnishes the carburetor and clogs the filter. Fuel filter replacement is 0.5 hours, but carburetor cleaning adds 2-3 hours. Tank may need dropping and cleaning if contamination is severe. Replace fuel filter every season if car sits in winter.

Estimated cost: $150-500
