Symptoms

•Ticking noise from the engine compartment
•Decreased engine performance
•Engine misfire or rough idle
•Check engine light illuminated
•Loss of oil pressure
•Unusual vibrations during operation

Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to check for any related diagnostic trouble codes (DTCs)
2
Inspect the oil level using the dipstick and check for signs of contamination or low oil levels
3
Listen for the ticking noise while the engine is idling, and check if it changes with engine speed
4
Visually inspect the engine for loose components, such as heat shields, or signs of wear on belts and pulleys
5
Check the valvetrain components by removing the valve cover (if accessible) to look for any signs of wear or damage
6
Perform a compression test on the engine cylinders to determine if there is a leak in any cylinder
7
Inspect the exhaust system for leaks that may cause similar ticking sounds
