1974 ALFA ROMEO SPIDER

Typical onset: 60,000-90,000 mi

Symptoms: Heavy knocking from lower engine, Sudden drop in oil pressure, Metal shavings in oil, Catastrophic failure if ignored

Fix: These SPICA-injected four-cylinders are unforgiving if oil changes are skipped or low oil is run. Bearing failure typically requires full engine rebuild including crank grinding, new pistons/rings if cylinder walls are scored. Expect 35-45 labor hours for complete rebuild with machine work.

Estimated cost: $4,500-7,500

Symptoms: Rough idle and hesitation, Hard starting when warm, Fuel weeping from pump, Loss of power under load

Fix: The SPICA pump is both brilliant and infuriating—specialists are rare and rebuilds run $1,200-2,000 just for the pump. Filter maintenance is critical but often neglected. Many owners convert to Weber carburetors (12-15 hours labor) as a permanent fix rather than chase SPICA gremlins.

Estimated cost: $2,000-3,500

Symptoms: Visible rust perforation along rocker panels, Soft or cracked floor under carpet, Rear suspension mounting points compromised, Jacking points collapsing

Fix: Italian steel from this era rusts if you look at it wrong. Rockers and floors are bolt-in replaceable but require 25-40 hours of skilled metal work. Rear subframe rust is structural and dangerous—can cause suspension detachment. Pre-purchase inspection must include underside evaluation.

Estimated cost: $3,000-8,000

Typical onset: 70,000-110,000 mi

Symptoms: Grinding into second gear when cold, Difficult shifting or balking, Whining in neutral that changes with clutch, Gear oil leaks from input shaft seal

Fix: Second gear synchros are the usual victim, but bearing noise means a full rebuild is due. Transmission out and rebuild runs 18-24 hours. Parts availability has improved with aftermarket support but expect delays. Not a catastrophic failure but makes the car unpleasant to drive.

Estimated cost: $2,200-3,200

Typical onset: 50,000-80,000 mi

Symptoms: Blue smoke on deceleration, Oil consumption exceeding 1 qt per 500 miles, Fouled spark plugs, Failed emissions testing

Fix: The aluminum head uses brass valve guides that wear oval, allowing oil past the seals. Requires head removal, guide replacement, valve job, and new seals. Often discovered during compression/leak-down testing. Budget 16-22 hours labor. Address this before it damages exhaust components.

Estimated cost: $1,800-2,800

Typical onset: 40,000-70,000 mi

Symptoms: Excessive drivetrain clunk on throttle, Vibration at idle in gear, Shifter rattling, Visible cracking in rubber mounts

Fix: Rubber mounts last 10-15 years maximum in this application. Transmission mount is most critical and fails first. All mounts can be done in 3-4 hours. Cheap insurance and dramatically improves refinement. Use OEM-spec replacements, not generic parts-store mounts.

Estimated cost: $400-700
