BOQUILLA OIL VOLVO 1542320

Function and technical context

The 1542320 oil nozzle is a component of the engine's internal lubrication circuit that directs the flow of pressurized oil to specific friction points such as bearings, camshaft and critical wear areas. It acts as a precision injector within the forced lubrication system, ensuring that the flow reaches exactly where the engine needs it to reduce friction between moving metal parts. Deterioration or clogging of this nozzle directly compromises the lubricant film in the areas it protects, which can lead to accelerated wear of internal components, increased working temperature and, in extreme cases, engine seizure. Its timely replacement is decisive to maintain the lubrication conditions that Volvo Penta specifies for these marine diesel engines.

When to replace this part?

The most common symptoms of a clogged or damaged oil nozzle include uneven oil pressure or oil pressure below the normal range indicated on the dashboard, higher than usual lubricant consumption, and the appearance of dry metallic noises inside the block, especially during cold starts. It is recommended to inspect the condition of this nozzle at each major engine overhaul or when disassembling the lubrication circuit, usually coinciding with oil and filter changes during seasonal overhauls. Replacing it preventively when detecting any anomaly in the oil pressure avoids costly breakdowns inside the engine that could leave the boat immobilized at sea.
