What This Part is Used For
The intake valve stem seal fits around the intake valve stem and helps regulate the amount of engine oil that passes between the valve stem and valve guide.
The valve guide requires lubrication, but excessive oil entering past the guide can reach the intake port and combustion chamber. The valve stem seal helps control this oil flow while allowing the valve to move normally.
Why Intake Valve Stem Seals Matter
Valve stem seals operate in a high-temperature environment and can become hardened, worn or damaged over time. A deteriorated seal may allow excess oil into the combustion chamber.
During a cylinder-head rebuild, replacing valve stem seals while the valves are already removed can prevent having to disassemble the valve train again later.
When to Replace Valve Stem Seals
- During a complete cylinder-head rebuild
- When replacing intake or exhaust valves
- When servicing valve guides
- If seals are hardened, cracked, flattened or damaged
- When excessive oil usage is traced to the cylinder head
- After overheating or cylinder-head damage
- During a complete powerhead overhaul
