8-98009885-0 TUBE; GUIDE,OIL LEVEL GAUGE ISUZU for ZX200-3/4HK1

Creates a Stable, Sealed Pathway for Accurate Oil Level Checks

The oil level gauge guide tube is a rigid metal conduit that provides a dedicated, sealed pathway from the top of the engine down into the oil pan sump. This ensures the dipstick is guided cleanly to the correct depth for consistent, accurate oil level readings. Found on a wide range of Isuzu applications—including TFR/TFS pickups with 4JA1, 4JB1, 4JJ1, and 4JK1 engines, as well as NPR/NQR trucks with 4HE1 and 4HK1 enginesand heavy-duty equipment like the ZX870-5G with 6WG1 engine—this component is available through numerous genuine part numbers (e.g., 8-97113-145-0, 8-97249-184-0, 8-98206-113-1, 8973814903).

Corrosion-Resistant Steel with a Precision Sealing Interface

Manufactured from durable, corrosion-resistant steel, the guide tube is engineered to withstand continuous thermal cycling, vibration, and exposure to engine oil and moisture. Many designs incorporate a dedicated sealing O-ring at the base of the tube where it meets the engine block or oil pan. A separate tube gasket (e.g., 5-09623-002-0) or guide tube washer (e.g., 0-91614710-0) is also used to ensure a leak-proof seal, preventing oil from escaping the crankcase and maintaining system integrity.
