WOD GM LS Oil Accumulator Adapter Body (-10 AN)
WA01003LS-ST
The WOD LS Oil Accumulator Adapter Body provides a dedicated connection point for adding an oil accumulator to a GM LS-based engine. Designed around -10 AN oil plumbing, this precision-machined billet aluminum adapter makes it easier to route pressurized oil between the engine and accumulator in rock crawlers, race vehicles, LS swaps, and custom chassis applications.
Built for engines exposed to steep angles, hard acceleration, braking, sustained RPM, and other conditions that can momentarily uncover the oil pickup, this adapter provides a compact foundation for an auxiliary oil-pressure system. Straight and 90-degree adapter options allow builders to select the plumbing direction that best fits the available chassis and exhaust clearance.
Includes:
- (1) LS Oil Accumulator Adapter Body
- (1) Gasket
- (2) 1/8" NPT Plugs
- (1) Selected -10 AN Adapter: Straight or 90°
Note: Oil accumulator, hoses, valves, mounting clamps, and additional plumbing components are sold separately unless otherwise noted. Verify engine compatibility, fitting orientation, and available clearance before ordering.

- Select the straight or 90° fitting based on chassis, exhaust, engine-mount, and hose-routing clearance.
- Verify the adapter mounting location and gasket alignment before installation.
- Route hoses away from exhaust heat, sharp edges, and moving suspension or steering components.
- Use hose and fittings rated for engine-oil temperature and pressure.
- Professional installation is recommended for custom oiling systems.
- Compatibility should be confirmed on engines with non-standard oil pans, accessory drives, or aftermarket oiling components.
FAQ
What does an oil accumulator do?
An oil accumulator stores pressurized engine oil and releases it when engine oil pressure drops. This can help protect bearings and other lubricated components during brief periods of oil starvation caused by steep climbs, hard acceleration, braking, cornering, or sustained high-RPM operation.
Why add an oil accumulator to an LS engine?
LS-powered off-road and race vehicles can experience rapid oil movement inside the pan as the vehicle climbs, lands, accelerates, or operates at severe angles. An accumulator adds a temporary reserve of pressurized oil, providing another layer of protection when the pickup becomes momentarily uncovered.
What does this adapter body do?
The adapter creates a dedicated connection between the engine's pressurized oil system and the accumulator plumbing. It allows oil to flow into the accumulator when pressure is available and return to the engine when system pressure drops, depending on the accumulator and valve configuration.
Why use -10 AN plumbing?
-10 AN hose is commonly used in performance oil systems because it provides substantial flow capacity without being excessively difficult to route. The full system must still be designed around hose length, fitting restriction, valve type, accumulator size, and available oil pressure.
Should I choose the straight or 90° adapter?
Choose the fitting that creates the cleanest hose route with the least interference. A straight fitting may provide a more direct flow path, while a 90° fitting can be useful where frame rails, headers, motor mounts, or other components limit clearance.
What are the 1/8" NPT ports used for?
The 1/8" NPT ports may be used for compatible pressure-sensing or oil-system accessories, depending on the installation. Unused ports should be sealed with the included plugs using a thread sealant suitable for engine-oil systems.
Can this be used with a remote oil filter or oil cooler?
It may be incorporated into a broader custom oiling system that includes an accumulator, remote filter, or oil cooler. However, the complete plumbing layout must be designed to maintain proper oil flow and pressure. The supplied information does not define a universal routing plan for every combination.
Does an oil accumulator replace a properly designed oil pan?
No. An accumulator helps cover brief pressure-loss events, but it does not correct inadequate baffling, improper oil level, pickup clearance problems, excessive bearing clearance, or a failing oil pump. It should be treated as supplemental protection rather than a repair for an underlying oiling problem.
Can the accumulator pre-oil the engine before startup?
Many accumulator systems can pre-oil the engine when configured with the correct valve and operating procedure. Whether that feature is available depends on the accumulator, valve, and plumbing components used with this adapter.
What should be checked after installation?
Inspect the system for leaks, confirm stable oil pressure, verify that hoses do not contact hot or moving parts, and follow the accumulator manufacturer's instructions for air charge, valve operation, and oil-level adjustment. Adding an accumulator can change the total oil capacity required by the system.
