Question 494Motor Plants - Assistant Engineer

The correct answer is B) increased oil consumption. Excessive wear at part No. 11, which is likely a component of the engine's lubrication system, would result in increased oil consumption. When engine parts experience excessive wear, it can lead to oil leaks or reduced oil sealing, causing the engine to consume more oil than normal. This is because the worn parts are no longer able to contain the oil within the engine's internal components effectively. The other options are incorrect because: A) improper timing is not directly related to excessive wear at part No. 11, C) lost compression is more likely due to issues with the engine's cylinder or piston sealing, and D) low oil pressure is a symptom that could result from the increased oil consumption, but is not the direct cause.
