Parts for Detroit Diesel 8V71 Turbo – Oil Pump Section

The Detroit Diesel 8V71 Turbo engine remains one of the most dependable and widely used two-stroke diesel engines ever built. Designed for both marine and industrial applications, this powerplant delivers robust performance, reliability, and service longevity when properly maintained. A key component in ensuring that longevity is the engine’s lubrication system — and at the heart of that system is the oil pump.

The oil pump section for the Detroit Diesel 8V71 Turbo includes a wide range of components: rebuilt oil pumps, gaskets, shims, seals, oil coolers, and pressure regulators — each designed for precise fit and long-term dependability. Whether you’re performing a complete engine rebuild or a simple maintenance job, the right oil pump components make all the difference in preventing wear, maintaining oil pressure, and protecting vital engine parts.

Understanding the Oil System of the Detroit Diesel 8V71 Turbo

The oil system of the 8V71 Turbo engine serves multiple critical functions:

• Lubrication of internal components such as bearings, pistons, and camshafts.

• Cooling, as oil absorbs and dissipates heat from frictional surfaces.

• Cleaning, removing contaminants and metal shavings from the lubrication circuit.

• Protection, creating a pressurized barrier that minimizes metal-to-metal contact.

To achieve this, the oil system relies on a high-quality oil pump, a network of oil coolers, a pressure regulation system, and an array of gaskets and seals that prevent leaks and ensure consistent flow. Over time, as components wear or accumulate sludge, maintaining oil flow becomes crucial for engine health.

Rebuilt Oil Pumps for the Detroit Diesel 8V71 Turbo

Right-Hand Rebuilt Oil Pump
This right-hand configuration oil pump is engineered to provide steady lubrication pressure across all operating speeds. Rebuilt to OEM specifications, it ensures durability equivalent to a new unit while maintaining affordability. Ideal for marine propulsion systems or stationary applications, this pump is sold with a refundable core deposit — reflecting Diesel Pro Power’s commitment to sustainability and recycling high-quality components.

Left-Hand Rebuilt Oil Pump
Engines that utilize the opposite rotation setup require a left-hand pump to match gear direction and flow dynamics. Like the right-hand version, the left-hand oil pump for the 8V71 Turbo is rebuilt and tested for pressure, volume, and tolerance. It ensures optimal lubrication and is a direct-fit replacement for standard Detroit Diesel 8V71 Turbo applications.

Scavenging-Type Oil Pump (for 6V71 through 16V92 engines)
This pump, also compatible with the 8V71 Turbo, assists in maintaining oil circulation through the turbocharger and crankcase. Its scavenging function ensures that excess oil is quickly returned to the sump, preventing pooling in low points or turbo seals. In turbocharged setups like the 8V71T, this helps avoid smoking and carbon buildup.

Gaskets and Sealing Components

The gaskets used in the oil system are engineered to maintain tight seals under high temperature and pressure conditions. Each gasket type serves a specific function within the system:

Oil Pump Gasket – Provides a secure seal between the oil pump and block surface to prevent leaks.
Crankshaft Front Cover Gasket – Maintains oil tightness around the crankshaft gear housing.
Oil Cooler Gasket – Prevents coolant and oil from mixing inside the cooler assembly.
Oil Pump Pad Cover Gasket – Ensures a firm seal over inspection or cover areas on the oil pump housing.

For the Detroit Diesel 8V71 Turbo, gasket integrity is especially critical due to the engine’s high-speed oil flow rates and pressurized two-stroke system. Regular inspection and replacement during rebuilds help maintain long-term performance.

Oil Coolers and Heat Dissipation

The Detroit Diesel 8V71 Turbo engine relies on efficient oil cooling to maintain optimal viscosity and temperature balance. Diesel Pro Power offers a full selection of plate-type oil coolers:

• 13-Plate Oil Cooler – Designed for compact installations and standard-duty operation.

• 13-Plate Cooler with Nipples – Allows easy hose connections for external cooling loops.

• 16-, 18-, and 24-Plate Oil Coolers – For heavy-duty or continuous-duty marine applications requiring higher oil volume throughput.

Each cooler is precision-manufactured for high heat transfer efficiency and corrosion resistance. These coolers prevent overheating of the lubricating oil, extending both oil and engine component life — essential for turbocharged engines running under continuous high load.

Shims, Regulators, and Pressure Components

Oil Pump Shims (.05, .010, .020 thickness)
Shims allow technicians to precisely set oil pump clearance and adjust oil pressure to factory specifications. Fine-tuning the clearance between the gear face and cover ensures optimal performance, preventing over-pressurization or inadequate flow.

Oil Pressure Regulator Valve
This valve automatically regulates oil flow to maintain proper pressure throughout the system, protecting bearings and preventing oil starvation under high RPM conditions.

Oil Pressure Regulator Spring
Works in conjunction with the valve to maintain correct resistance. Over time, the spring may weaken, leading to pressure fluctuations — replacing it during service ensures stable operation.

Oil Relief Valve
Prevents excess pressure from damaging seals or oil lines. It allows excess oil to bypass safely, keeping internal components protected during cold starts or peak load conditions.

Filtration and Adaptation Components

Oil Filter Base (Cartridge Type)
Serves as the foundation for the oil filter assembly, housing the cartridge and ensuring correct flow routing through the filtration element.

Oil Filter Adaptor (Cartridge to Spin-On Conversion)
A modern upgrade for older engines — this adaptor converts traditional cartridge filters to spin-on filters, simplifying maintenance and improving sealing reliability.

Oil Filter Gaskets and Seals
These maintain a leak-free connection between the filter base and engine block. Regular replacement prevents minor leaks that can lead to major oil loss in high-vibration environments.

Spin-On Oil Filter
Modern spin-on filters are built to withstand high pressures and trap fine particles efficiently. For the 8V71 Turbo, maintaining clean oil flow through the turbocharger bearings and crankshaft journals is vital for engine longevity.

Oil Filter Removal Wrench
Ensures easy servicing, preventing damage to the filter or housing during replacement.

Dipsticks, Tubes, and Measuring Components

Accurate oil level monitoring is critical on any Detroit Diesel 8V71 Turbo engine.

Oil Dipstick (various lengths) – Available in standard 27¼-inch and extended 44¼-inch versions for different installation configurations.
Dipstick Tube – Guides the dipstick into the sump, ensuring accurate measurement and preventing oil splash-out.
Dipstick Guide – Supports and aligns the dipstick assembly for easy use.

Each of these components ensures reliable readings and prevents overfilling or low-level operation — both of which can cause serious damage to engine internals.

Oil Coolant and Housing Seals

The cooling system’s connection to the oil circuit involves several specialized seals:

Water Manifold to Oil Cooler Seals (2½", 2¾", and 2 3/16")
These maintain tight coolant connections to the oil cooler housing, preventing oil-water cross-contamination — a common cause of catastrophic failure in marine engines.

Oil Cooler Housing Gaskets
These gaskets provide the barrier between the oil cooler and engine block, sealing both the oil and coolant passages.

Oil Cooler Cover Gaskets
Designed to handle both temperature and vibration, ensuring the integrity of the cover during continuous operation.

Pressure Switches and Monitoring Devices

To keep the Detroit Diesel 8V71 Turbo running efficiently, pressure monitoring is essential.

Fuel and Oil Pressure Switches (5, 10, 20, and 27 PSI)
These switches activate alarms or gauges based on system pressure. They provide operators with early warning of low oil pressure or system irregularities — a vital safeguard for both industrial and marine applications.

Each switch features a durable brass body with 1/8 NPT threads, ensuring compatibility and reliability in demanding environments.

Paints, Gasket Makers, and Finishing Products

Detroit Diesel Green Engine Paint
Authentic color for restoration or maintenance work, protecting metal surfaces from corrosion while maintaining OEM appearance.

Ultra Blue RTV Gasket Maker
A sensor-safe, high-temperature silicone compound ideal for sealing oil pans, timing covers, and accessory flanges. Used widely during engine reassembly to ensure leak-free results without compromising sensor operation.
