Symptoms

•Check engine light illuminated
•Blue smoke from the exhaust
•Oil warning light appearing on the dashboard
•Frequent need for oil top-ups
•Poor engine performance or rough idling
•Unusual engine noises (ticking or knocking)

Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to check for any related engine codes.
2
Inspect the oil level and condition using the dipstick; note the frequency of required oil changes.
3
Visually inspect for oil leaks around the engine, oil pan, and valve cover.
4
Perform a compression test on each cylinder to check for piston ring wear.
5
Conduct a cylinder leakage test to identify potential leaks past the piston rings or valves.
6
Check PCV (Positive Crankcase Ventilation) system for clogs or malfunctions that could lead to increased oil consumption.

Solution
