Reduce oil pollution erosion, withstand high temperature. Replace the Valve Seals to solve the aging problem. Rubber provides uniform clamping force across the entire valve cover. Keyhole and other design features prevent over tightening

The valve oil seal can prevent oil from entering the intake and exhaust pipes, avoid oil loss, prevent the mixture of gasoline and air and exhaust gas from leaking, and prevent engine oil from entering the combustion chamber
