Excessive or unusual smoke coming from your exhaust can indicate engine trouble. Different colors of smoke can signal various issues.
Blue smoke often means burning oil, which may result from worn-out piston rings or valve seals.
White smoke can indicate a coolant leak, which might be a sign of a blown head gasket or a cracked engine block.
Black smoke generally points to an overly rich fuel mixture, possibly due to a malfunctioning fuel injector or a clogged air filter.
