⚠️ Safety Warnings

Important safety information - read before proceeding

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

Symptoms

•Engine oil level drops significantly between oil changes
•Blue smoke from the exhaust during acceleration
•Engine misfires or rough idling
•Increased frequency of oil top-ups
•Oil leaks observed under the vehicle

Diagnostic Steps

1
Check the engine oil level using the dipstick to confirm low oil levels.
2
Scan for error codes using an OBD-II scanner to identify any related engine issues.
