Question

Quizplus · Accepted Answer

Technician A is correct because converting press-in type rocker arm studs to threaded ones is a recognized method for enhancing the engine's performance and reliability. This process involves milling the area around the stud and then threading it to accept screw-in studs, which are more durable and can handle higher performance demands. Technician B is also correct because during an engine overhaul, replacing wear components like stamped steel rocker arms can prevent future failures and ensure reliable operation. Stamped steel rocker arms can wear over time, and replacing them during an overhaul is a proactive measure to maintain engine performance and longevity.
