Alfa Romeo 3.2 V6
The 3.2-litre V6 with JTS direct injection combines Busso sound with modern fuelling — theoretically the best of both worlds, in practice a challenge. The direct injection introduces fuel dilution into the oil, requiring shortened oil change intervals (7,000–10,000 km). The sound remains the typical 60-degree Busso with its multi-voiced howl from 5,000 rpm, the power delivery slightly fuller in the mid-range than the naturally aspirated Busso. 240 hp in the GT, 250 hp in the GTV and Spider. Timing chains instead of belt (three chains as on the 932A.000). Chain kit sourcing increasingly difficult — parts sometimes coming from Australia (Holden variant).
GTV 3.2 Facelift — Under 500 Units, the Rarest Busso
The 3.2-litre version of the 916 GTV arrived only with the facelift from 2003 and was built in fewer than 500 units. The engine is identical to the GT, the chassis older and more characterful: shorter wheelbase, more direct turn-in, but noticeably more body movement than the stiffer GT. The gearbox is considered undersized for the torque — second gear grinds at high mileage. Clutch torsion springs wear from 30,000 km. Even so: the GTV 3.2 is the original among Busso coupes, rare enough for collector status, dynamic enough for any Sunday morning.
Engine Weaknesses 7
The 3.2 V6 JTS of the 159/Brera is known for timing chain wear. Cold-start rattling from around 80,000–100,000 km is a warning sign. Repair costs 3,000–5,000 €.
Symptoms: Metallic rattling on cold start that diminishes after warm-up; with further wear it becomes permanent
The 20V variant of the 2.4 JTD develops cylinder head cracks at higher mileages, typically between intake and exhaust valves. Cause is sustained thermal stress. The 10V version is considered more robust.
Symptoms: White smoke, dropping coolant level without oil contamination, hard coolant hoses after engine shutdown (pressure build-up), loss of heating performance
The direct injection of the 3.2 JTS prevents self-cleaning of the intake valves. Carbon deposits form especially during short-trip driving.
Symptoms: Power loss, rough running, misfires
Identical problem to 932A and 1.9 JTD: the crankcase ventilation freezes in extreme frost and pumps oil into the intake tract. The 936 2.4 JTD part is explicitly listed in the Alfisti parts catalogue.
Symptoms: Oil smoke after cold start in sub-zero temperatures, crankcase pressure build-up, oil in the intake area
The cam phaser solenoid (variator) can jam from contamination or aging. A faulty solenoid prevents variable valve timing and triggers fault code P0013/P0014. Oil contamination promotes sticking.
Symptoms: Engine warning light with P0013/P0014, sluggish throttle response, reduced power especially in the lower rev range
Early direct injection generation without intake port wetting: carbon deposits on the intake valves build up inevitably. Result: power loss, rough running. Walnut blasting or chemical valve cleaning required.
Symptoms: Power drop from approx. 60,000 km, rough cold running, increased fuel consumption, occasional misfires under load.
The 3.2 V6 JTS requires 10W-60 oil and tends towards elevated consumption and premature chain wear when oil changes are skipped.
Symptoms: Oil level drop, blue smoke under load
Vehicle Weaknesses 7
Weld seams on longitudinal members, engine bay crossmember and strut tops corrode. Underbody steel structures have no adequate protection — especially weld points on the tunnel area and rear wheel arches are affected. Extensive restoration required when heavily rusted.
The manual gearbox on the GTV shows synchromesh wear at higher mileage. Difficult engagement of certain gears is a typical symptom. Gearbox overhaul costs several hundred to over a thousand euros.
Rust forms preferentially at underbody weld seams, inner wheel arches and fuel tank guard. Underbody protection lifts off and releases moisture. Rear wheel arch inner panels and tunnel seams are particularly affected.
Blocked drain channels in the scuttle panel below the windscreen direct rainwater into the footwell. Leaves and dirt block the drain pipes. In heavy rain, water runs into the passenger footwell blower.
The air conditioning condenser sits directly in the line of stone impacts in front of the radiator and is frequently damaged. Refrigerant also escapes through normal leakage after 3–4 years. Condenser replacement including recharge costs approximately 500 €.
Electric windows fail through failed motors or control units. Plastic drive components break; switches and relays become brittle. When both sides fail simultaneously, the relay under the boot carpet is often to blame.
Power steering pressure lines become porous and leak at connectors. On the V6 the line runs in a hard-to-reach location under the air filter and radiator. Fluid loss continues without repair.
