Description

What does a housing oil nozzle do?

The housing oil nozzle plays a critical role in the engine lubrication system by directing oil spray toward the underside of the piston. This process is essential for removing heat accumulated in the piston crown and reducing friction at the piston pin and connecting rod bushings. By maintaining thermal balance, especially in turbocharged engines, this component helps prevent piston ring sticking and ensures long-term engine reliability.

Engine compatibility and fitment

This component is compatible with LASO systems and is specifically designed for heavy-duty engine applications. Due to the importance of spray geometry, it is vital to match the nozzle with the specific engine code and cylinder position to ensure the oil reaches the piston base correctly rather than hitting the cylinder liner wall.

Installation and maintenance

Technicians should verify the connection style—whether it is a bolted flange, banjo-connected, or threaded body—before installation. It is recommended to check the check-valve opening pressure against service data to prevent pressure drops at idle. Ensuring correct torque and seating in the block gallery prevents oil leakage and maintains proper gallery pressure.

Selection guidance

Selecting the correct nozzle based on OE reference ensures a precise fit within the crankcase architecture. Consult your authorized distributor for fitment guidance.

OE cross-reference

0101 030 (Housing Oil Nozzle Crankcase) is the equivalent of the LASO OE number. This part directly replaces LASO OE number 20014315.

FAQ

What is the function of a housing oil nozzle?
It directs a precise spray of oil onto the underside of the piston to dissipate heat from the piston crown and lubricate the piston pin assembly.
How can I ensure I select the correct nozzle for my engine?
The best approach is to use the OE number of the removed part along with the specific engine code to ensure correct tube angle and connection style.
What happens if an incorrect nozzle is installed?
An incorrect angle can cause oil to hit the cylinder liner instead of the piston, leading to overheating, potential block damage, or loss of gallery pressure.
What are common signs of a failing oil nozzle?
Symptoms may include insufficient piston cooling, unusual engine temperature rises under load, or a drop in main gallery pressure at idle.
What are the OE reference numbers of this part?
0101 030 directly replaces LASO OE number 20014315.
