These 90913-02090 valve stem oil seals are critical small sealing parts for Toyota 3L diesel engine. Hardened, cracked or worn valve oil seals will cause engine burning oil, obvious blue smoke when accelerating, frequent oil top-up and carbon deposit accumulation inside cylinders. They must be replaced when disassembling cylinder head, overhauling valve train or solving oil consumption issues. Each seal undergoes dimensional tolerance and high-temperature durability testing before packaging.
