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).
Spider 3.2 — Busso V6 in the Open Air
The 916 Spider with the 3.2-litre Busso is the most emotional of all Busso experiences: roof down, third gear, 5,500 rpm — the 60-degree V6 howls skyward above your head. The body flexes noticeably more in fast transitions than the GTV, the hood is rarely truly waterproof, the plastic rear screen fogs over after a few years. None of it matters — the sound with the roof down compensates for every compromise. Just as rare as the GTV 3.2, emotionally richer by a whole dimension. Front tyre wear: a fresh set every 15,000 km.
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
