PCV System Malfunction: A clogged or faulty Positive Crankcase Ventilation system can cause excessive pressure to build inside the crankcase, forcing oil past weak seals and into the combustion mix. Blue smoke is the direct result of oil burning within the combustion chamber, strongly suggesting an oil leak into the cylinders.
Diagnosing Oil Out of Exhaust Smoke and Its Causes
A compression test or leak-down test is often the first step, measuring the ability of the cylinders to hold pressure. These signs are the vehicle’s warning system indicating that something is critically wrong internally.
Diagnosis and Testing Mechanics use a systematic approach to pinpoint the exact source of the leak. Additionally, a mechanic might perform a "wet test," where a small amount of oil is introduced into the cylinder before retesting; if compression improves, it confirms that the rings are the culprit.
