Exhaust or Tailpipe Smoke

Exhaust or tailpipe smoke indicates engine issues based on color:

• White (steam) is normal condensation but thick/persistent smoke suggests coolant leak (head gasket).
• Blue/Gray signals burning engine oil (worn rings, seals, turbo).
• Black means too much fuel (rich mixture, clogged air filter).

Occasional puffs are normal, but excessive smoke requires mechanical inspection
