Question

Quizplus · Accepted Answer

Technician A is correct that installing a compression ring upside down can cause oil consumption because the ring won't seal properly. Technician B is also correct that the top compression ring groove usually suffers more wear than the other ring grooves, as it has the most load and is exposed to the hottest combustion gases. Therefore, both technicians are correct.
