Quizplus · Accepted Answer

Both statements made by Technician A and Technician B are correct. The clearance between the plunger and lifter body in hydraulic lifters is indeed very small, typically around 0.0002 inches, to maintain proper hydraulic pressure and function. Technician B's statement is also correct because dirt particles found in engine oil are generally larger than 0.0002 inches, which is why maintaining clean oil and proper filtration is crucial to prevent lifter and engine damage.
