1987 FSO POLONEZ

Typical onset: 50,000-80,000 mi

Symptoms: loud ticking or tapping from valve cover especially when cold, progressive loss of power, rough idle, metal particles in oil

Fix: The Fiat-derived engine uses soft metallurgy lifters that wear cam lobes prematurely. Full job requires lifter replacement (all 8), camshaft inspection/replacement, and often valve adjustment. Budget 8-12 hours labor for proper diagnosis and replacement. Cam resurfacing rarely successful—replacement typical.

Estimated cost: $800-1,500

Typical onset: 60,000-100,000 mi

Symptoms: white smoke from exhaust, coolant loss with no visible leaks, overheating, milky oil, rough running when warm

Fix: Factory head gasket material and torque specs were marginal. Requires cylinder head removal, gasket replacement, and resurfacing (head warps easily). Always check for cracks during resurface—common on cylinders 2-3. Plan 10-14 hours labor. Use updated gasket set if available.

Estimated cost: $1,200-2,200

Typical onset: 40,000-70,000 mi

Symptoms: severe clunking when shifting or accelerating, vibration through shifter, visible engine/trans sag, difficulty engaging gears

Fix: Original rubber mounts deteriorate rapidly—often found completely separated. Requires replacement of both transmission and engine mounts as they fail in tandem. 3-5 hours labor. OE replacements equally poor; upgraded polyurethane if available.

Estimated cost: $300-600

Typical onset: 70,000-110,000 mi

Symptoms: severe vibration at idle, squealing from front of engine, visible wobble on crankshaft pulley, accessory belt throwing or shredding

Fix: The rubber ring between balancer hub and outer ring delaminates. If caught early, replacement straightforward (3-4 hours). If it fails completely, can damage crankshaft snout or timing cover. Always inspect during timing service.

Estimated cost: $400-700

Symptoms: hard starting, stalling, poor acceleration, fuel smell, rough idle

Fix: Fuel tank and lines corrode internally; rubber hoses deteriorate. Fuel filter clogs frequently (30k service intervals minimum). Carburetor models suffer varnish buildup. Plan aggressive filter replacement schedule and tank inspection. Tank replacement often needed by 100k miles. 2-8 hours depending on scope.

Estimated cost: $150-800

Typical onset: 60,000-90,000 mi

Symptoms: transmission fluid leaks under vehicle, slipping when hot, burnt smell, low fluid level

Fix: Steel lines rust through at bends and connections. External cooler lines typically fail first. Requires line replacement and full fluid flush. 2-4 hours labor. Check radiator-mounted cooler for internal leaks (trans fluid in coolant).

Estimated cost: $250-500

Typical onset: 100,000-140,000 mi

Symptoms: excessive oil consumption (1qt per 500mi), blue smoke, low compression across multiple cylinders, rod knock, main bearing noise

Fix: The Fiat 1600 in Polonez trim rarely survives past 120k without major work. Soft pistons, poor ring seal, bearing wear. Full rebuild includes machine work, pistons, bearings, timing components, gaskets. 25-35 hours labor. Parts scarcity makes this often uneconomical.

Estimated cost: $2,500-4,500
