Question 14Motor Plants - QMED

The correct answer is C) low bearing oil pressure. A dirty lube oil strainer can restrict the flow of lubricating oil, leading to low oil pressure in the engine's bearings. This reduced oil pressure can increase wear and damage to the engine bearings over time. The other answer choices are incorrect because: A) Crankcase dilution is caused by fuel or coolant mixing with the engine oil, not a dirty oil strainer. B) Low lube oil temperature is more likely caused by a problem with the oil cooling system, not the oil strainer. D) Excessive oil consumption is more likely caused by oil leaks or worn engine components, not a dirty oil strainer specifically.
