Looking for a genuine Toyota oil nozzle sub-assembly No.1 (part number 15708-51010) with exact factory specifications and fitment? This Toyota Oil Nozzle is manufactured to strict OEM standards and designed to deliver precise engine lubrication, cooling, and cleaning for dependable long-term performance you can trust.

Critical Engine Lubrication Component for Piston Cooling
The oil nozzle sub-assembly is a vital part of the cylinder block lubrication system. It is responsible for:

• Precisely spraying pressurized oil onto piston undersides for cooling

• Reducing piston crown temperatures during high-load operation

• Preventing oil starvation, scoring, and thermal expansion issues

• Supporting efficient oil gallery flow to connecting rods and bearings

• Ensuring reliable operation under extreme heat and RPM conditions

This genuine nozzle is specifically engineered for Toyota Land Cruiser VDJ200 series (2007-2021) with V8 engines, mounted in the block to target No.1 cylinder piston cooling.

Factory-Quality Design & Durable Construction
Manufactured using premium stainless steel and precision-drilled orifices with engineering tolerances, this OEM oil nozzle:

• Meets Toyota’s exact spray pattern, pressure, and flow specifications

• Integrates seamlessly with main oil gallery, block passages, and pistons

• Ensures consistent lubrication across temperature and oil pressure ranges

• Provides long-lasting durability against clogging and erosion

• Features secure press-fit or threaded retention for vibration resistance

Whether replacing during engine rebuild or addressing piston overheating, this genuine component helps maintain your Land Cruiser's legendary durability.

Why Replacement Matters
Owners commonly replace the oil nozzle when experiencing symptoms such as:

• Excessive piston slap, knocking, or high oil consumption

• Overheating in cylinder No.1 or uneven temperatures

• Low oil pressure warnings or bearing wear

• Scoring marks on pistons during teardown inspection

• Reduced power or detonation under heavy loads

• Oil analysis showing metal particles from lubrication failure

Installing a genuine nozzle restores precise piston cooling, reduces wear, and ensures balanced engine operation.

Avoiding Incorrect or Aftermarket Substitutes
Using an incompatible or poorly designed nozzle can lead to:

• Inadequate piston cooling causing seizure or ring land failure

• Oil spray misalignment starving critical components

• Clogging from debris leading to complete lubrication loss

• Premature engine failure and high rebuild costs

• Imbalanced cylinder cooling and power inconsistencies

Choosing the correct Toyota genuine oil nozzle sub-assembly ensures reliable lubrication, optimum piston protection, and long-term durability.

Before purchasing, always verify the vehicle model (Toyota Land Cruiser VDJ200), engine type (4.5L/4.6L V8 diesel), cylinder position (No.1), and part number (15708-51010) to ensure accurate fitment and dependable operation you can trust.
