The 1985 Alfa Romeo Milano (75 in Europe) with the 2.5L Busso V6 is a characterful rear-transaxle sport sedan plagued by neglect-related engine wear, aging rubber mounts, and Italian electrics. Most survivors have questionable maintenance histories.
Timing Belt Failure Leading to Valve/Piston Damage
Common · high severityTypical onset: any mileage if service history unknown
Symptoms: sudden loss of power, catastrophic engine noise, no start after belt snap, bent valves confirmed on compression test
Fix: The Busso V6 is an interference engine—belt failure destroys valves and often pistons. Requires cylinder head removal, valve replacement, possible piston damage repair. If heads are warped or cracked, full rebuild or used engine swap becomes necessary. 20-40 hours labor depending on collateral damage.
Estimated cost: $3,500-8,000
Worn Main and Rod Bearings with Oil Pressure Loss
Common · high severityTypical onset: 80,000-150,000 mi
Symptoms: low oil pressure at idle when hot, knocking or ticking from lower end, oil pressure warning light flickering, metallic rattle on cold start that doesn't go away
Fix: Neglected oil changes and marginal oiling design lead to bearing wear. Requires full engine-out teardown, crank inspection/polishing, new bearings, and typically new oil pump. If crank is scored beyond .010 undersize, replacement or full long-block swap needed. 30-45 hours.
Estimated cost: $4,000-7,500
Leaking Cylinder Head Gaskets
Common · medium severityTypical onset: 70,000-120,000 mi
Symptoms: external oil seepage between head and block, coolant loss with no visible external leak, white smoke on startup, overheating under load
Fix: Aluminum heads on iron block with age-hardened gaskets. Both heads need removal, surface inspection for warpage (common), new gaskets, and timing belt/water pump replacement while apart. 16-22 hours labor.
Estimated cost: $2,500-4,200
Worn Hydraulic Valve Lifters (Tappets)
Common · medium severityTypical onset: 60,000-100,000 mi
Symptoms: loud ticking/clacking from valve covers, noise worse when cold, may quiet slightly when warm, loss of power due to poor valve timing, noise persists even after oil change
Fix: Original lifters collapse with age and contaminated oil. All 12 lifters should be replaced together. Requires cam cover removal, cam timing setup. Often done during head gasket job. 8-12 hours standalone.
Estimated cost: $1,200-2,000
Failed Transmission/Transaxle Mounts
Common · medium severityTypical onset: any—rubber degrades with age regardless of miles
Symptoms: clunking on throttle lift or application, excessive drivetrain shunt, vibration at idle, difficulty shifting gears smoothly
Fix: Rear transaxle layout uses multiple rubber mounts that harden and crack. Requires lift access to rear subframe. Mounts are NLA from Alfa, aftermarket quality varies. 3-5 hours to replace all mounts.
Estimated cost: $600-1,200
Clogged or Failing Fuel Filter Causing Fuel Starvation
Occasional · medium severityTypical onset: any—depends on fuel quality and tank condition
Symptoms: stumbling or hesitation under load, loss of power at highway speeds, difficulty starting when hot, rough idle that clears with throttle
Fix: In-line fuel filter clogs from tank rust and old fuel varnish. Filter is cheap but often reveals larger issue with rusty fuel tank contaminating system. Filter replacement: 1 hour. If tank cleaning needed, add 6-8 hours.
Estimated cost: $150-300 filter only; $800-1,500 with tank service
Electrical Gremlins: Grounds, Relays, and Wiring Corrosion
Common · low severitySymptoms: intermittent no-start, gauges reading erratically, lights dimming or flickering, fuel pump not priming, dash warning lights staying on
Fix: Typical Italian car aging: corroded grounds behind dashboard and engine bay, oxidized relay contacts, brittle wiring insulation. Diagnosis time-consuming—plan on 2-6 hours chasing down individual issues. Not one fix but death by a thousand cuts.
Estimated cost: $200-800 per issue
Only buy if you're handy, patient, and accept that engine work is likely; a well-maintained example is sublime, but most have been neglected into money pits.
