1978 ALFA ROMEO ALFETTA

Typical onset: 60,000-100,000 mi

Symptoms: Clunking on deceleration or gear changes, Vibration through floor and shifter, Excessive driveline movement visible under throttle, Rough engagement into first gear

Fix: The transaxle-in-rear layout uses multiple rubber mounts and a torque tube that deteriorate badly. Expect 4-6 hours labor to drop the driveline, replace transmission mount, torque tube bushings, and differential mounts. Often done as a package since access requires similar work.

Estimated cost: $800-1,400

Symptoms: Hard starting when cold or hot, Rough idle and stumbling, Fuel smell from engine bay, Complete no-start after sitting, Poor fuel economy and lack of power

Fix: The mechanical Spica injection requires someone who actually understands it—rare today. Aged fuel filters (often neglected), clogged injectors, deteriorated rubber lines, and out-of-spec pump timing are typical. Basic service (filter, lines inspection, idle adjustment) takes 2-3 hours. Full Spica rebuild or replacement with Weber conversion is 12-20 hours.

Estimated cost: $400-800 for service, $3,000-5,500 for Weber conversion

Typical onset: 80,000-140,000 mi

Symptoms: Deep knocking from lower engine at idle, Metal shavings in oil, Sudden drop in oil pressure, Catastrophic failure with rod through block in worst cases

Fix: The twin-cam four is fragile when oil changes are skipped or the wrong oil is used. Main bearings fail first, then rods. You're looking at engine-out, full disassembly, and machine work. Engine R&R is 12-15 hours, short block rebuild adds another 20-25 hours if you're doing pistons and rings too.

Estimated cost: $4,500-8,000 for proper rebuild with machine work

Typical onset: 100,000-150,000 mi

Symptoms: Grinding into second gear especially when cold, Difficult engagement into third, Popping out of gear under load, Whining in neutral that changes with clutch pedal

Fix: The rear-mounted transaxle is robust but syncros wear, especially second gear. Full rebuild requires dropping the entire driveline assembly (8-10 hours) plus 12-15 hours for disassembly, parts replacement, and reassembly. Clutch is often done simultaneously since access is identical.

Estimated cost: $2,800-4,200

Symptoms: Sudden loss of power and valve train noise, Metal-on-metal scraping from front of engine, Engine won't turn over after belt/chain failure, Bent valves confirmed by compression test

Fix: This is an interference engine—timing failure means valve-to-piston contact. If the crank itself is damaged (rare but happens with severe bearing failures), you're into full engine disassembly, machine shop time, and possible crankshaft replacement. Timing belt service alone is 4-5 hours; valve repair adds 8-12 hours; crank work means full teardown.

Estimated cost: $1,200-2,000 for timing and valve work, $5,000-9,000 if crank needs replacement

Symptoms: Visible rust perforation in trunk floor around transaxle, Clunking from rear suspension on bumps, Misalignment that won't correct with adjustments, Cracking paint or bubbling around rear shock towers

Fix: Italian steel rusts aggressively, especially around the transaxle tunnel and rear suspension pickup points. Structural rust requires metalwork—patch panels or fabrication—which can run 15-30 hours depending on severity. Surface rust is manageable; structural compromise is a project.

Estimated cost: $2,000-6,000 depending on extent
