Description

What does a housing oil nozzle do?

This critical engine component is designed to be fitted within the cylinder block to direct pressurized oil onto the underside of the piston skirt. By providing targeted cooling to the piston crown, it helps manage the extreme thermal loads generated during combustion, which is vital for the longevity of heavy-duty diesel engines.

Compatibility and engine fitment

This part is compatible with Mercedes-Benz engines. Proper selection ensures that the oil spray reaches the correct area, preventing heat buildup that could lead to piston damage or ring sticking.

Installation and maintenance guidance

For successful installation, technicians should verify the connection style—whether it is a bolted flange, banjo connection, or threaded body—against the existing part. It is essential to confirm that the spray tube angle matches the original specification to ensure oil hits the piston base rather than the cylinder liner wall.

Selection and troubleshooting

When replacing this component, always refer to the engine code and ensure that the check valve opening pressure aligns with manufacturer requirements to maintain stable oil gallery pressure at idle.

OE cross-reference

0101 029 (Housing Oil Nozzle Crankcase) is the equivalent of the Mercedes-Benz OE number. This part directly replaces Mercedes-Benz OE number 4571801443.

FAQ

What is the function of a housing oil nozzle?
It directs pressurized engine oil onto the underside of the piston to dissipate heat from the piston crown and provide lubrication to the piston pin.
How can I ensure correct fitment for my engine?
It is vital to match the spray tube angle and connection style (such as banjo or threaded) with the original part and verify it against your specific engine code.
What are the risks of using an incorrect nozzle?
Selecting a nozzle with a different geometry or spray angle can cause oil to hit the cylinder liner instead of the piston, leading to overheating or block damage.
Why is check valve pressure important in these nozzles?
The check valve maintains gallery pressure at idle; an incorrect valve pressure can cause a drop in pressure or insufficient cooling at higher speeds.
What are the OE reference numbers of this part?
0101 029 directly replaces Mercedes-Benz OE number 4571801443.
