Question 54 of 533

The decrease of the oil pressure is caused by one of the following reasons:

A the clogging of the oil pump strainer;
B the operation of the engine at low speeds;
C the incorrect installation of the oil filter.

Explanation

The oil pump strainer has the role of taking the oil from the oil pan and sending it through the lubrication circuit of the engine. If this strainer becomes clogged with impurities, deposits, or carbon particles, the oil flow to the pump will be reduced, which will lead to a decrease in the pressure in the system. This problem often occurs when the oil is not changed on time or when the oil filter becomes clogged and no longer retains impurities effectively.

The correct answer is: A
