Removing the oil cap and looking for sludge helps determine whether the cylinder is broken or the head gasket is worn out. Check whether there are oil or water leakages in the engine, which can cause internal engine problems and result in excessive oil consumption. Checking the oil level and its color on the dipstick determines whether the oil needs to be changed or whether there is an interior engine problem.

Determine engine problems by examining the condition of the oxygen sensor and catalytic converter. This helps in making the decision whether to replace them to avoid failure of the engine oil light. Check for a worn-out timing belt, which can cause the valves and the piston to be damaged.

When the engine is running, listen for knocking or tapping sounds as it helps to pinpoint if the gasoline is igniting prematurely in the combustion chamber of the cylinders. Presence of a blocked air filter indicates that the Volvo engine has not been serviced for an extended time, and a low level of oil illustrates points to an oil leakage or a faulty crank case ventilation.
