How Tight Should Valve Stem Seals Fit. intake valve stem seals are usually designed with a tighter fit around the valve stem to reduce the amount of oil drawn into the combustion chamber during the intake stroke. measuring valve stem seal performance valve stem seals must accomplish two contradictory goals. stem sealing plays an important role in valve operation, to avoid leakage from the valve stem area to the environment. this compressive force is necessary to generate mechanical stress in the packing material to make it seal tightly against the stem of the valve and the interior wall of the bonnet. Two nuts threaded onto studs maintain proper force on the packing rings. learn more about the common signs valve stem seals are leaking, how to proactively check them & the most common causes of. if a positive seal fits the stem too tight, the hydrodynamic seal may be lost as the oil film is scraped off the stem. First, they must seal the valve stem.
