Alfa Romeo 33 Problems: Common Issues and Repair Costs
The Alfa Romeo 33 is a true gem from the 80s and 90s. Built between 1983 and 1995, it came with Alfa’s iconic boxer engines, sharp handling, and distinct Italian flair. But like most classics, it comes with its fair share of issues. If you’re looking to buy, restore, or maintain an Alfa 33, it’s essential to understand what goes wrong and how much it will cost to fix. Here’s a full guide to the most common problems and real-world repair costs based on UK prices.
1. Rust – The Biggest Killer of the Alfa 33
What goes wrong: Rust is the number one issue with the Alfa 33. Early models had little rust protection, and many were not properly maintained. Common rust zones include wheel arches, sills, floors, doors, and suspension mounts.
Signs to look for:
- Bubbling paint on arches and door bottoms
- Holes in the floor or boot
- Damp carpets
- MOT corrosion advisories
Repair costs:
- Small rust patch repair: £100 to £200
- Welding sills or arches: £250 to £500
- Full body rust restoration: £2,000 to £5,000 or more
2. Oil Leaks from the Boxer Engine
What goes wrong: The 33’s flat-four engines are fun but known for leaking oil. Leaks usually come from rocker covers, sump gaskets, or crankshaft seals.
Signs to look for:
- Oil puddles under the car
- Oil smell when driving
- Frequent top-ups needed
Repair costs:
- Rocker cover gasket: £60 to £100
- Crank seal replacement: £120 to £180
- Full engine reseal: £400 to £800
3. Carburettor and Fuel System Issues
What goes wrong: Most Alfa 33s came with twin Weber or Dell’Orto carbs. They can fall out of tune, and fuel lines often perish with age. Later models with fuel injection are more reliable but still not immune to issues.
Signs to look for:
- Poor cold starts
- Engine hesitation or rough idle
- Strong fuel smell in or around the car
Repair costs:
- Carb rebuild or tuning: £150 to £300
- Fuel pump replacement: £80 to £120
- Fuel line replacement: £100 to £200
4. Gearbox and Clutch Wear
What goes wrong: Gearboxes are generally solid but second gear often crunches due to worn synchros. Clutch cables on these cars can snap or stretch over time.
Signs to look for:
- Crunching when changing gear
- Gear stick stiffness
- Clutch pedal feels off or too heavy
Repair costs:
- Clutch kit and labour: £300 to £500
- Gearbox rebuild: £600 to £1,000
- Clutch cable replacement: £80 to £150
5. Brake System Faults
What goes wrong: Brake lines and components on these older cars corrode. Master cylinders and rear drum brakes can fail or seize.
Signs to look for:
- Spongy brake pedal
- Brake fluid loss
- Car pulls to one side under braking
Repair costs:
- Brake line replacement: £150 to £300
- Front discs and pads: £100 to £200
- Master cylinder replacement: £120 to £180
- Rear drum brake service: £120 to £180
6. Suspension and Steering Issues
What goes wrong: Worn shocks, bushes, and joints are common. Rear suspension bushes especially tend to crack with age. Handling becomes vague or noisy as parts wear.
Signs to look for:
- Banging or clunking over bumps
- Car feels unstable at speed
- Uneven tyre wear
Repair costs:
- Front shocks (pair): £100 to £150
- Suspension bushes (set): £80 to £150
- Complete suspension rebuild: £400 to £700
7. Electrical Gremlins
What goes wrong: Like most classic Alfas, the 33 suffers from electrical faults. Earth issues, flaky connectors, and worn switches are all very common.
Signs to look for:
- Flickering dashboard lights
- Wipers or indicators not working properly
- Random electrical faults
Repair costs:
- Wiring fault diagnostics: £80 to £150
- Switch or stalk replacement: £30 to £80
- Loom repairs: £150 to £300
8. Interior Wear and Trim Damage
What goes wrong: The cabin materials in the 33 don’t age well. Dashboards crack, seats wear out, and trim panels become loose or brittle.
Signs to look for:
- Rattling interior parts
- Cracked dashboard or missing trim
- Sagging roof liner
Repair costs:
- Dashboard replacement: £200 to £400 (used)
- Seat retrim (per seat): £150 to £300
- Roof lining repair: £180 to £300
Is the Alfa Romeo 33 Still Worth Owning?
Absolutely — but only if you’re prepared for regular maintenance and potentially some restoration work. These cars offer a great driving experience and are becoming more collectible, especially the 1.7 and 16v versions. Parts availability is decent thanks to Alfa specialists, but body panels and trim can be hard to source.
Well-kept examples are getting rarer, and values are starting to climb. If you find a solid, rust-free car with a good service history, it can be a rewarding classic to own and drive.
Final Tip – Get It Professionally Inspected Before You Buy
Buying a classic car like the Alfa 33 without a proper inspection is a huge risk. Rust, mechanical wear, or hidden faults can easily turn a cheap buy into a costly project.
