Estimated Time

4-8 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems.
•Allow the engine to cool before disassembling any components.

Symptoms

•Check engine light illuminated
•Noticeable blue smoke from the exhaust
•Frequent oil level drops requiring regular top-ups
•Engine misfires or rough idling
•Oil leaks under the vehicle
•Increased fuel consumption

Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to identify any engine-related issues.
2
Check oil level and condition using the dipstick to determine the extent of oil consumption.
3
Inspect for external leaks by examining the oil pan, gaskets, and seals for signs of oil seepage.
4
Perform a compression test to assess the health of the engine's cylinders.
5
Examine PCV (Positive Crankcase Ventilation) system for blockages or malfunctions that could lead to increased oil consumption.
6
Inspect the valve seals and piston rings for wear or damage, which can contribute to oil burning.
