Question 69 of 485

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

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

Explanation

The oil pump strainer has the role of drawing oil from the oil pan and sending it through the engine lubrication circuit. 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 drop in system pressure. This problem occurs frequently when the oil is not changed on time or when the oil filter is clogged and no longer efficiently retains impurities.

The correct answer is: A
