Oil Pan Assembly 8-97383067-2 8973830672 For ISUZU NLR85 NMR85 NNR 4JJ1T Diesel

The Oil Pan Assembly (OEM Numbers: 8-97383067-2 / 8973830672) is a premium-quality, direct replacement engine component designed specifically for ISUZU NLR85, NMR85, and NNR series light-duty trucks equipped with 4JJ1T diesel engines. This complete oil pan assembly — also known as an oil sump or crankcase lower pan — is a critical part of the engine's lubrication system. It serves as the reservoir for engine oil, allowing oil to drain back from the engine after circulation and providing a steady supply of oil to the oil pump. The pan also helps dissipate heat from the engine oil and seals the bottom of the crankcase to prevent oil leakage and contamination.

• OE Quality: Manufactured to strict ISUZU dimensional and material specifications for perfect fit and function.
• High-Strength Construction: Durable steel or cast aluminum alloy withstands vibration, thermal cycling, and mechanical stress.
• Precision-Formed Sealing Surface: Machined mating flange ensures a leak-proof seal with the engine block and oil pan gasket.
• Proper Oil Capacity: Designed to hold the correct volume of engine oil for reliable lubrication and cooling.
• Drain Plug Provision: Includes standard drain plug opening for easy oil changes.
• Restores Oil Containment: Eliminates oil leaks caused by a cracked, bent, or rusted oil pan.

Professional mechanic installation recommended:

1. Ensure engine is cool — Allow the engine to cool completely before disassembly.
2. Disconnect battery — Always disconnect the negative terminal before working.
3. Drain engine oil — Remove the drain plug and drain the engine oil into a suitable container.
4. Remove the oil pan — Unbolt and remove the old oil pan; carefully separate it from the engine block.
5. Remove the old gasket — Peel off the old oil pan gasket; note its orientation.
6. Clean all mating surfaces — Thoroughly clean the engine block and oil pan surfaces; remove all old gasket material, oil, and debris.
7. Inspect the engine block — Check for warpage, cracks, or damage on the block mating surface.
8. Install the new gasket — Position the new oil pan gasket on the engine block; ensure proper alignment with bolt holes.
9. Install the new oil pan — Carefully position the new oil pan on the gasket; hand-start all bolts.
10. Torque bolts — Tighten bolts in a criss-cross pattern to manufacturer torque specifications. Do not over-tighten.
11. Install the drain plug — Install the drain plug with a new washer if applicable; tighten to specification.
12. Refill with engine oil — Fill with the correct grade and quantity of engine oil.
13. Check for leaks — Start the engine and inspect the oil pan joint and drain plug for oil leakage.
14. Road test — Test drive to verify proper sealing and no oil leaks.
