90913-02053 valve stem oil seals are critical tiny sealing components for Toyota 1KZ series turbo diesel engines. Hardened, cracked or deformed old valve oil seals will lead to severe oil burning fault: blue smoke from exhaust pipe, frequent oil level drop, excessive carbon accumulation inside cylinders and decreased engine power. It is a mandatory replacement part when disassembling cylinder head, repairing valve train or troubleshooting high oil consumption problems. Each seal passes dimensional tolerance and high-temperature durability inspection before delivery.
