Over time, these rings can wear out or break due to excessive heat or poor maintenance. Prompt attention is essential to prevent further damage to the engine and catalytic converter.
Mechanical Failures That Let Oil Into the Exhaust Stream
Failed Piston Rings or Cylinder Walls The rings inside an engine cylinder serve to seal the combustion chamber and control oil consumption. Blown Head Gasket A head gasket sits between the engine block and cylinder head, sealing the combustion chambers and coolant passages.
This section outlines the primary mechanical failures that result in oil being expelled through the tailpipe. Common Causes of Oil in the Exhaust The presence of raw or burnt oil in the exhaust stream points to a breach between the internal combustion system and the atmosphere.
Mechanical Failures That Let Oil Into the Exhaust Stream
Driving with excessive oil consumption can lead to catastrophic engine failure if left unaddressed. The financial cost of repairing a seized engine is exponentially higher than addressing a gasket or ring issue early.
