Technician A says that when viewing the piston assembly from the top, all of the end gaps for the piston rings should be at the 12 o'clock position. Technician B says that compression rings may be marked with a small dot that must face the bottom of the piston when installed. Who is correct?

Question

Quizplus · Accepted Answer

Technician A is incorrect because the end gaps of the piston rings should not be aligned; they should be staggered around the piston to prevent compression loss and oil leakage. Technician B is incorrect because the small dot or marking on compression rings indicates the top side, which should face the top of the piston, not the bottom.
