Description

What does a housing oil nozzle do?

This housing oil nozzle plays a critical role in the engine lubrication system by spraying pressurized oil onto the underside of the piston. By directing oil flow toward the piston skirt, it effectively removes heat from the combustion chamber, preventing thermal overload during high-load operation. This component is essential for maintaining the longevity of heavy commercial vehicle engines.

Engine compatibility and fitment

This part is compatible with Mercedes-Benz engines and serves as a reliable replacement for OE components. It is engineered to match the specific spray configuration required for optimal piston cooling and lubrication within the crankcase assembly.

Installation and maintenance

For proper installation, technicians should verify that the connection to the main oil gallery is secure to prevent pressure drops. Ensuring the nozzle is seated correctly within the engine block helps maintain consistent oil spray patterns, which is vital for preventing piston pin friction and managing thermal loads in turbocharged applications.

System performance and cooling

When replacing this component, it is recommended to inspect the surrounding gallery and seals to ensure optimal system pressure and spray accuracy.

OE cross-reference

0101 031 (Housing Oil Nozzle Crankcase) is the equivalent of the LASO and Mercedes-Benz OE numbers. This part directly replaces LASO OE number 20014301. It also replaces Mercedes-Benz OE numbers 3521800143, 3661800143.
