Technician A says that a new or freshly rebuilt engine will run at higher engine temperatures during the break-in period. Technician B says that you should check oil pressure during the break-in period. Who is correct?
A A only
B Bonly
C Both A and B
D) Neither A nor B
The correct answer and explanation is:
The correct answer is C: Both A and B.
Explanation:
Technician A is correct in stating that a new or freshly rebuilt engine will run at higher engine temperatures during the break-in period. During the break-in phase, internal engine components such as the pistons, rings, and cylinders are still settling and wearing in. This process generates additional friction, leading to higher engine temperatures. These elevated temperatures are generally expected and part of the normal operation, but the engine should be carefully monitored to ensure it does not overheat.
Technician B is also correct in saying that you should check oil pressure during the break-in period. The oil system plays a crucial role in lubricating the engine and reducing friction. During break-in, because the engine parts are still adjusting to each other, there may be more wear initially, which could impact oil pressure. Monitoring the oil pressure ensures that the lubrication system is functioning properly and that the engine is not experiencing any internal issues that could lead to premature wear or failure.
Both of these actions are vital to ensuring that the engine operates correctly and does not suffer damage during its initial use. Regular monitoring of both the temperature and oil pressure during the break-in period helps prevent potential problems, such as overheating or insufficient lubrication, which could result in costly repairs later on.
