Does an Oil Leak in the Exhaust Pipe Require a Major Overhaul?

[SanJeffrey]

Whether an oil leak in the exhaust pipe requires a major overhaul depends on the severity of the leak. The details are as follows: 1. Minor oil leak: This may be caused by inherent defects in the vehicle and does not require a major overhaul. 2. Severe oil leak: A major overhaul is necessary, as severe oil leakage can lead to increased fuel consumption, lack of acceleration power, accelerated engine wear, and other issues. The main function of the vehicle's exhaust pipe: It reduces the combustion speed and temperature in the engine cylinders, thereby improving emissions.
