Engine Valve Stem Oil Seal — Foton AUMARK Cargo Truck Valve Seal Replacement
This engine valve stem oil seal is a Kingstream OEM replacement valve seal for Foton AUMARK cargo trucks (2005+ model years) used in logistics, construction, and material handling applications. The valve stem oil seal is a small but critical engine component installed on each valve stem where it passes through the cylinder head — it prevents engine oil from leaking down the valve stem into the combustion chamber while allowing a controlled amount of oil to lubricate the valve guide. Worn valve seals cause blue exhaust smoke on startup, increased oil consumption, and carbon buildup on valves and spark plugs. 1.2kg with 20×18×15cm neutral packaging. Black color. Standard size. 1-year warranty. MOQ 1 piece. Kingstream OEM for Foton AUMARK truck fleet engine maintenance.
INSTALLATION: Step 1 — Remove the valve cover, rocker arms, and pushrods. Step 2 — Remove the valve springs using a valve spring compressor. Step 3 — Pry off the old valve stem seal from the valve guide boss. Step 4 — Clean the valve guide boss thoroughly. Step 5 — Install the new seal by pushing it onto the valve guide until it snaps into place — use a seal installation sleeve to protect the seal lip from damage by the valve stem keeper grooves. Step 6 — Reinstall valve springs, retainers, and keepers. Step 7 — Reinstall rocker arms and adjust valve clearance to Foton AUMARK specification. Step 8 — Install a new valve cover gasket and valve cover. For Foton AUMARK truck fleet engine maintenance, contact us. Kingstream OEM.
SYMPTOMS OF WORN VALVE SEALS: Blue or white smoke from the exhaust on cold startup that diminishes as the engine warms up, excessive oil consumption without visible external leaks, fouled spark plugs with oily carbon deposits, and carbon buildup on intake valves causing rough idle and power loss. Kingstream OEM.
