Question

Quizplus · Accepted Answer

Technician A is correct because the windage tray is designed to prevent air pockets from forming in the oil at high engine speeds. This is important because air pockets can reduce oil pressure and cause damage to engine components. 
Technician B is also correct because priming the lubrication system is important to ensure that all of the engine's oil passages are filled with oil when the engine is first started after a rebuild. This helps to prevent damage to bearings and other engine components due to lack of lubrication. Therefore, both technicians are correct.
