1977 ALFA ROMEO ALFETTA

Typical onset: 80,000-120,000 mi

Symptoms: knocking or rumbling from bottom end especially on cold starts, rapidly dropping oil pressure, metallic debris in oil filter, sudden catastrophic seizure if ignored

Fix: Full engine rebuild required once bearings spin. Needs crank inspection/machining, all new bearings, typically includes rings and rod bearings while you're in there. 25-35 hours labor for full teardown, machine work, and reassembly. Many opt for short block replacement instead of rebuild due to age and parts availability.

Estimated cost: $4,500-7,500

Typical onset: 60,000-100,000 mi

Symptoms: clunking on acceleration/deceleration, excessive driveline vibration, difficulty shifting smoothly, visible sagging or cracked rubber at transaxle mount points

Fix: All rubber mounts from engine to rear transaxle need replacement as a set. The transaxle mount is especially problematic and frequently tears. 4-6 hours labor to access and replace all critical mounts. OEM rubber deteriorates badly; polyurethane upgrades available but create more NVH.

Estimated cost: $600-1,200

Typical onset: 70,000-110,000 mi

Symptoms: blue smoke on startup and deceleration, consuming 1+ quart per 500-800 miles, fouled spark plugs, loss of compression

Fix: Requires engine removal and full top-end work minimum, but typically cascades into full rebuild when bearing condition is assessed. Ring replacement alone is 18-22 hours; most techs recommend addressing bearings simultaneously. If caught early, sometimes gets by with just rings and hone.

Estimated cost: $3,200-5,800

Symptoms: visible rust perforation in rockers, floor pans, rear shock towers, bubbling paint along seams and door bottoms, structural weakness in jack points, fuel tank mounting area corrosion

Fix: Italian steel from this era rusts aggressively, especially in front subframe mounting points and rear shock towers which are structural and safety-critical. Proper repair requires panel replacement and welding, 15-40 hours depending on extent. Many cars are economically totaled by rust.

Estimated cost: $2,500-8,000

Typical onset: varies

Symptoms: hard starting when cold or hot, rough idle and stumbling, poor fuel economy, hesitation under load, fuel leaks at pump or lines

Fix: The mechanical SPICA injection system requires specialized knowledge increasingly rare in shops. Pump rebuilds need expert service (few providers left). Often includes replacing hardened fuel lines and filter. Timing adjustment is critical and tedious. 6-10 hours for comprehensive diagnosis and service by someone who knows these systems.

Estimated cost: $1,200-2,800

Typical onset: 90,000-140,000 mi

Symptoms: grinding into second gear especially when cold, difficulty engaging third gear, crunching sounds during shifts, jumping out of gear under load

Fix: Second gear synchros wear first, followed by third. Transaxle must come out (easier than front-engine cars due to rear location, but still 8-12 hours). Rebuild includes synchros, bearings, and seals. Parts availability is declining; some builders source used gearsets.

Estimated cost: $2,200-3,800
