Top Causes of White Smoke from Exhaust in Land Rover Discovery Sport

• Head gasket failure allowing coolant into combustion chamber — most serious cause
• Cracked cylinder head from overheating episode
• Cracked engine block — rare but possible after severe overheating
• Automatic transmission fluid leaking into intake via vacuum modulator (on older automatics)
• Normal white vapour during cold start (condensation) — not a fault if clears in 2 minutes

How We Diagnose White Smoke from Exhaust on Land Rover Discovery Sport

• Combustion gas test (sniff test) on coolant reservoir — detects exhaust gases in coolant
• Coolant pressure test to confirm system integrity
• Engine oil dipstick check for milky oil or foam (water contamination)

Prevention

Never continue driving with an overheating engine — one episode of severe overheating can cause the head gasket failure that leads to white smoke.
