Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, compression tester, screwdrivers, oil catch pan, coolant tester.
Safety Warnings: Disconnect the battery before working on electrical systems. Allow the engine to cool before opening the radiator.

2. Address Engine Oil Consumption (If Blue Smoke)

Sub-steps:
1. Change Oil and Filter: Use the manufacturer-recommended oil type and replace the oil filter.
2. Check Valve Seals: Remove valve covers and inspect valve seals for wear. Replace if necessary.
3. Inspect Piston Rings: If oil consumption persists, consider replacing piston rings, which requires engine disassembly.

3. Address Coolant Leak (If White Smoke)

Sub-steps:
1. Check Head Gasket: Perform a pressure test on the cooling system to check for leaks. Replace the head gasket if defective.
2. Flush Cooling System: Drain and flush the cooling system to remove any contaminants.
3. Replace Thermostat: If the thermostat is faulty, replace it to ensure proper engine temperature regulation.

4. Address Fuel System Issue (If Black Smoke)

Sub-steps:
1. Inspect Fuel Injectors: Check for clogged or leaking fuel injectors and replace as necessary.
2. Replace Air Filter: Ensure the air filter is clean to allow proper air intake, and replace if dirty.
3. Adjust Fuel Pressure: Test and adjust the fuel pressure regulator to ensure proper fuel delivery.
