1970 ALFA ROMEO GIULIA

Symptoms: Low oil pressure at idle when hot, Rod knock or main bearing rumble, Excessive blowby or smoking on deceleration, Metal particles in oil filter

Fix: Most survivors need complete engine rebuilds due to age and wear cycles rather than mileage. Proper rebuild includes crank regrind, new bearings, pistons, rings, cam bearings, timing chain, oil pump. Budget 40-60 hours for engine-out rebuild with machine work. Quality varies wildly depending on parts sourcing—NOS or Italian parts vs generic aftermarket.

Estimated cost: $6,500-12,000

Symptoms: Excessive shifter slop or vague gates, Clunking under acceleration/deceleration, Difficulty selecting second or reverse, Transmission visible sagging when viewed from below

Fix: Rubber transmission mount deteriorates over decades, allowing excessive movement. Often coincides with worn shift linkage bushings and selector fork issues. Mount replacement alone is 3-4 hours; full linkage refresh adds another 4-6 hours if transmission must come out for selector work.

Estimated cost: $800-2,200

Symptoms: Excessive valve train noise (ticking/clattering), Poor cold starting, Loss of power above 4,500 RPM, Erratic idle quality

Fix: Twin-cam head needs proper valve adjustment every 3,000 miles; most haven't seen it in years. Complete valve job includes cam inspection, new followers, valve guides, seat cutting, springs, seals. Head-on work is 12-18 hours; head removal/reinstall adds 8-10 hours. Cam wear often discovered during valve jobs on neglected engines.

Estimated cost: $2,800-5,500

Symptoms: Hard starting when hot or cold, Stumbling or flat spots during acceleration, Fuel smell in cabin or engine bay, Rough idle that won't stabilize

Fix: Decades-old varnish in dual Weber carburetors, corroded fuel lines, and degraded tank linings are endemic. Proper fix involves tank removal/cleaning or replacement, all fuel lines, filter, fuel pump rebuild, and complete carburetor overhaul with synchronization. Total 12-16 hours for comprehensive fuel system service.

Estimated cost: $1,800-3,200

Symptoms: Deep knocking synchronized with engine speed, Catastrophic oil pressure loss, Metal shavings throughout engine, Sudden seizure in worst cases

Fix: When oil starvation or age-hardened bearings let go, crank typically needs regrinding (0.010" to 0.030" undersize common). Requires complete teardown, crank removal, machine shop work, new bearings, reassembly with careful clearance checks. This is full rebuild territory—50-65 hours engine-out with all ancillary seals and gaskets.

Estimated cost: $7,500-13,500

Typical onset: 80,000-150,000 mi

Symptoms: Grinding into second gear, Jumping out of third under load, Whining in multiple gears, Difficult or impossible reverse engagement

Fix: Five-speed gearbox is generally durable but synchros wear, bearings get noisy, and shift forks bend. Complete rebuild involves case splitting, new synchro rings, bearings, seals, shift fork inspection/replacement. Gearbox R&R is 6-8 hours; rebuild adds 12-16 hours depending on parts availability and case condition.

Estimated cost: $3,200-5,800
