Description
What does a housing oil nozzle do?
This critical engine component is designed to be fitted within the cylinder block of heavy commercial vehicle engines. It functions by spraying pressurized oil directly onto the underside of the piston skirt, which effectively carries heat away from the combustion chamber and helps maintain thermal balance in high-performance engines.Compatible vehicles and engines
The part is compatible with Mercedes-Benz engines. Precise selection is vital because even within the same engine family, nozzles may differ in tube angle or connection style to ensure the spray hits the piston base rather than the cylinder liner wall. For correct fitment, always verify the part against the engine code and original specifications.Installation and maintenance
Installation should be performed by a workshop technician to ensure proper seating in the gallery opening. Depending on the design, these components may feature a bolted flange, banjo connection, or a threaded body. Ensuring the check valve opens at the correct pressure threshold is essential for maintaining main gallery pressure at idle and providing sufficient cooling during high engine speeds.Troubleshooting and selection
Selecting a high-strength component ensures reliable lubrication for the piston pin and connecting rod small-end bushing, reducing friction and preventing premature wear in heavy-duty duty cycles.OE cross-reference
0101 026 (Housing Oil Nozzle Crankcase) is the equivalent of the Mercedes-Benz OE number. This part directly replaces Mercedes-Benz OE number 4221800143.Other OEMs

FAQ
What is the function of a housing oil nozzle?
It directs pressurized engine oil onto the underside of the piston to provide essential cooling and lubrication for the piston pin, helping to manage thermal loads.
How can I ensure I select the correct nozzle for my engine?
It is recommended to use the engine code and verify the connection style—such as banjo or bolted flange—to ensure the spray angle matches the cylinder position.
What are the symptoms of a faulty oil nozzle?
A faulty nozzle can lead to insufficient piston cooling or a drop in main gallery pressure, potentially causing increased friction or thermal damage to pistons.
Can different nozzles be used in the same engine type?
No, even within one engine family, nozzles may have different tube angles or valve pressures; using an incorrect version can cause oil to hit the cylinder liner instead of the piston.
What are the OE reference numbers of this part?
0101 026 directly replaces Mercedes-Benz OE number 4221800143.
