1. Exact OEM dimension 90913-02117, perfectly matched the valve stem diameter of Toyota 2L series engine, no jamming or loose clearance during high-frequency valve reciprocating movement.
2. FKM fluororubber material withstands high exhaust temperature, diesel oil corrosion and long-term thermal aging, far superior durability compared with ordinary nitrile rubber seals.
3. Built-in coil spring continuously applies compression force on the sealing lip, automatically compensates wear gap to maintain stable sealing performance for long-term operation.
4. Standard 8-piece full set matches all 8 valves of 4-cylinder 2L engine, supporting complete cylinder head overhaul together with full gasket kit.

90913-02117 valve stem oil seals are vital small sealing components for Toyota 2L family diesel engines. Aged, hardened or cracked valve oil seals will cause obvious engine oil burning problem: thick blue smoke from exhaust pipe, frequent oil top-up, abnormal carbon accumulation inside cylinders and reduced engine power. It is mandatory to replace this 8pcs seal set when disassembling cylinder head, repairing valve train or solving oil consumption faults. Each seal undergoes dimensional tolerance and high-temperature durability testing before delivery.
