Valve Seals

ISKY valve stem oil seals positively control unwanted oil flow through the valve guides. They are particularly effective in racing engines by eliminating oil pollution of the combustion chamber, a horsepower robbing factor. Heavy duty steel and teflon construction. Installation requires the machining of the valve guide tops with our cutter. Isky valve stem oil seals are available in sets of 8, 12 & 16 for 4, 6 & 8 cyl. applications.
