Inspect and replace threaded plugs during engine disassembly. Inferior plugs easily crack and loosen, triggering sudden oil pressure failure and major engine damage. Repair workshops and parts dealers recommend stocking genuine 20799722 plugs. Match with sealing rings, expansion plugs and oil seals to assemble complete engine overhaul kit.
Oil seeps around plug thread, dust adheres to form oily dirt layer on engine surface
Sudden oil pressure alarm under heavy load, insufficient lubrication supply inside engine
Thread worn and pitted, driving groove deformed, unable to keep tight fastening state
All models for compatibility reference only. Premium threaded plug stably locks internal fluid pressure, eliminates oil passage leakage faults and protects core moving parts of heavy-duty engine.
