1972 ALFA ROMEO GTV

Symptoms: hard starting when cold or hot, rough idle and surging, poor fuel economy, black smoke from exhaust

Fix: Spica pump requires specialized knowledge—internal seals dry out, idle mixture screws get tampered with, and timing drifts. Proper rebuild and tuning takes 6-10 hours by someone who knows these systems. DIY tuning without experience makes it worse.

Estimated cost: $800-2,200

Symptoms: visible rust perforation along rocker panels, soft or cracked floor areas, suspension mounting points compromised, doors sag or don't close properly

Fix: These cars rust from the inside out. Proper repair means cutting out rockers, welding in new panels, and addressing floor pan sections. Expect 30-60 hours for comprehensive rust repair depending on severity. Many cars have had amateur patch jobs that hide deeper problems.

Estimated cost: $4,000-12,000

Typical onset: 50,000-80,000 mi

Symptoms: excessive drivetrain movement under acceleration, clunking when shifting or clutch engagement, vibration at idle that changes when putting in gear, shifter feels vague or rubbery

Fix: Original rubber mounts deteriorate and often collapse completely. Replacing all four mounts (two engine, two transmission) takes about 4-5 hours. Access is tight but straightforward. Polyurethane upgrades available but transmit more vibration.

Estimated cost: $400-800

Typical onset: 80,000-120,000 mi

Symptoms: oil pressure drops below 20 psi at hot idle, valve train noise increases with declining pressure, metallic knocking from lower end, oil pressure warning light flickers

Fix: These twin-cam engines need consistent oil changes with quality oil. Neglect leads to bearing wear. Proper fix requires engine-out, full disassembly, crank polishing or replacement, and new bearings. Engine R&R plus rebuild runs 35-50 hours depending on machine shop work needed.

Estimated cost: $4,500-8,000

Typical onset: 60,000-100,000 mi

Symptoms: gear oil spots on driveway or garage floor, visible wetness at pinion flange or axle tubes, differential whine if oil level drops significantly

Fix: Pinion seal replacement requires dropping the driveshaft and using proper spacer measurement—about 3-4 hours. Axle seals add another 2 hours per side if those are leaking too. Not difficult but needs correct preload setup.

Estimated cost: $300-700

Symptoms: intermittent gauge operation, lights dim or flicker, starter won't engage consistently, instruments work sometimes but not others

Fix: Italian electrics of this era used marginal connectors and minimal corrosion protection. Cleaning all ground points, replacing the main fuse box, and addressing corroded bullet connectors takes 4-6 hours of methodical work. Often overlooked in favor of chasing individual symptoms.

Estimated cost: $300-600
