Parts for Detroit Diesel 16V71 Turbo – Oil Pump Section

The Detroit Diesel 16V71 Turbo engine is one of the most iconic high-performance powerplants in the two-stroke Detroit Diesel family. Designed for demanding marine, industrial, and heavy-duty power generation applications, the 16V71 delivers robust output, reliability, and longevity when maintained with quality components. Central to its operation is a properly functioning lubrication system, anchored by the oil pump assembly and a network of seals, gaskets, valves, and oil coolers that ensure constant pressure and temperature regulation.

This catalog page highlights Diesel Pro Power’s full selection of oil system components for the Detroit Diesel 16V71 Turbo engine. Every item listed—whether a gasket, regulator valve, or oil pump shim—has been selected for precision compatibility, durability under high load conditions, and long-term performance reliability.

The Role of the Oil Pump System in the 16V71 Turbo Engine

The oil system in the Detroit Diesel 16V71 Turbo plays a critical role in lubricating internal components, reducing friction, and dissipating heat from bearings and rotating assemblies. Because this is a V16 two-stroke turbocharged engine, it depends on an exact balance of oil pressure and flow to maintain its efficiency.

Key elements of the lubrication circuit include:

• Oil pump assembly – draws oil from the pan and circulates it throughout the engine.

• Oil cooler and gaskets – regulate temperature and prevent overheating during heavy operation.

• Oil pressure relief and regulator valves – maintain steady pressure and protect the system from overloading.

• Dipsticks and tubes – provide accurate oil level measurement and ensure proper filling.

• Seals and shims – maintain tight tolerances and precise clearances between moving components.

Diesel Pro Power offers all of these components—tested, rebuilt where applicable, and ready to ship worldwide.

Precision Shims and Gaskets for Oil Pump Alignment

Maintaining the right oil pump alignment is essential to prevent excessive wear and pressure fluctuations. Diesel Pro Power offers oil pump shims in multiple thicknesses (0.05, 0.10, and 0.20) to allow for fine adjustments and perfect gear mesh. Each shim is built to OEM specifications for the Detroit Diesel Series 71 family and ensures a smooth oil flow path through the pump housing.

Proper gasket selection is equally important. The catalog includes oil pump gaskets, oil inlet gaskets, and regulator gaskets designed for optimal sealing under high pressure. Each gasket is resistant to oil degradation, high temperatures, and vibration—a must for 16-cylinder marine or stationary units.

Key gasket categories include:

• Oil pump base and inlet gaskets

• Oil cooler housing and cover gaskets

• Oil pan to block gaskets (main, front, and rear sections)

• Pressure regulator and relief valve gaskets

When replacing or rebuilding the oil pump, always inspect and replace all related gaskets and shims. A minor leak can cause a rapid drop in oil pressure, which could lead to bearing failure in as little as a few minutes of operation.

Oil Pressure Regulation and Relief Components

Oil pressure must remain stable under varying RPM and load conditions. Diesel Pro Power’s oil regulator and relief valves are precision-engineered to maintain factory oil pressure ratings for the Detroit Diesel 16V71 Turbo.

These valves open automatically when pressure exceeds design limits, diverting excess oil back to the sump. The oil regulator valve ensures a consistent oil feed to bearings and turbochargers, while the oil relief valve provides protection against sudden spikes that could damage seals or filters.

Both valves are made with hardened materials to resist scoring and distortion under heavy use. They are direct replacements for OEM components and can be easily installed with standard shop tools.

Oil Cooler Assemblies for Temperature Control

Lubrication temperature management is crucial for large displacement two-stroke engines. The Detroit Diesel 16V71 Turbo utilizes high-capacity oil cooler assemblies, available in 24-plate, 32-plate, and dual-unit configurations.

These coolers maintain optimal oil temperature by circulating engine oil through a heat exchanger where it transfers heat to the cooling water circuit. Diesel Pro Power provides both standard plate oil coolers and units with integrated nipples for simplified installation.

Every oil cooler includes precision-machined plates, heavy-duty end covers, and corrosion-resistant materials suitable for marine environments. Complementary gasket kits and housing seals ensure leak-free installation.

Supporting components include:

• Oil cooler gasket kits for all 71 Series configurations

• Oil cooler housing and cover gaskets

• Water manifold seals between the cooler and housing

• Installation kits for double oil cooler setups

Oil Filters and Filtration Adaptors

Clean oil is the life of any Detroit Diesel engine. For the 16V71 Turbo, Diesel Pro Power supplies both cartridge-typeand spin-on oil filters, along with adaptor kits to convert older cartridge systems to modern spin-on configurations.

Spin-on filters simplify maintenance and reduce downtime, while still providing excellent filtration efficiency. The filter adaptor assembly allows operators to upgrade without modifying the housing.

Supporting parts include:

• Oil filter base assemblies

• Gaskets for filter bases and adaptors

• Copper washers for sealing filter bolts and drain plugs

• Filter removal wrenches designed for Detroit Diesel, Caterpillar, and Cummins engines

Oil Pans, Dipsticks, and Measuring Components

Accurate oil level measurement is vital for high-output engines like the 16V71 Turbo. Diesel Pro Power carries a range of oil pan gaskets, dipsticks, and tubes built for the 16V71’s unique layout.

The 16V71 requires multiple gaskets per engine—two for the front and two for the rear sections—to ensure complete sealing of the lower crankcase assembly.

Available components include:

• Main oil pan gaskets for 12V71 and 16V71 engines

• Lower front and rear pan gaskets

• Replacement dipsticks in 27¼” and 44¼” lengths

• Matching dipstick tubes and guides for correct routing

Each dipstick assembly is built for durability and calibrated for the engine’s specific oil capacity.

Oil Pressure Switches and Sensors

Maintaining awareness of oil pressure in real time helps prevent catastrophic damage. Diesel Pro Power offers make/break pressure switches in 5, 10, 20, and 27 PSI ratings. These switches can be installed on control panels, alarm systems, or mechanical gauge setups.

Switches are compatible with Detroit Diesel and Cummins systems, using standard 1/8” NPT fittings. Whether for monitoring or automation, they provide dependable activation when oil pressure drops below safe thresholds.

Oil Cooler Seals and Water Manifold Interfaces

The oil cooling system also connects to the engine’s water manifold. Proper sealing between these interfaces is essential to prevent cross-contamination of oil and coolant. Diesel Pro Power offers high-quality seals and water manifold gaskets in several diameters (2”, 2½”, and 2¾”).

Made from heat- and oil-resistant rubber compounds, these seals are designed for the high temperatures and pressures typical in turbocharged engines. Using new seals during every oil cooler or manifold service ensures maximum reliability.

Maintenance and Replacement Recommendations

Proper lubrication system maintenance extends the life of the 16V71 Turbo engine significantly. Here are a few essential guidelines:

1. Inspect oil levels daily – particularly in marine engines operating under continuous load.

2. Replace oil and filters every 200–250 hours depending on conditions.

3. Clean the oil cooler annually, removing scale or sludge build-up that can restrict flow.

4. Replace gaskets and seals whenever the oil pump, cooler, or filter assembly is serviced.

5. Check oil pressure at idle and operating speeds; deviations may indicate pump wear or regulator valve malfunction.

6. Use only high-quality lubricants meeting Detroit Diesel’s specification for two-stroke engines.

Following these best practices minimizes frictional wear and prevents loss of compression caused by oil starvation.
