When your engine starts burning oil or you notice blue smoke at startup, worn valve stem seals are usually the culprit. These little seals sit at the top of each valve guide, controlling exactly how much oil reaches the valve stem for lubrication while keeping combustion gases from escaping past the guides. When they harden, crack, or wear out, oil gets pulled into the combustion chamber and burned, creating that telltale smoke and increasing oil consumption you don't want to see. What You're Getting Precise oil control that eliminates excessive oil burning and smoke Heat-resistant construction designed for high-temperature engine operation Exact-fit design that matches your Fendt's engine specifications Quality sealing material that maintains flexibility through thousands of heat cycles Direct replacement for original equipment seals Built for Real Farm Work This valve stem seal fits a wide range of Fendt tractors from the smaller 200 Vario series utility models up through the powerful 900 Vario series row-crop machines. Whether you're running a compact vineyard tractor or a high-horsepower field machine, these seals handle the demanding conditions of agricultural engines that run long hours under heavy loads. Made to Last Farm tractors operate in extreme conditions with wide temperature swings, heavy loads, and extended run times. These valve stem seals use materials specifically engineered for agricultural diesel engines, maintaining their sealing properties through years of heat cycling and vibration. The construction resists the hardening and cracking that cause premature failure in cheaper seals. Good to Know Valve stem seal replacement requires cylinder head removal and valve service, making it ideal timing for a complete valve job if your engine has high hours. Always replace seals in complete sets rather than individually - mixing old and new seals creates uneven sealing. If you're experiencing oil consumption issues, check compression and leak-down tests first to rule out worn rings or other internal problems.
