Valve Stem Runout. valve seat runout tolerances will vary based on stem size, head diameter, seating angles, etc. the neway valve concentricty gauge is a quick and accurate method of measuring valve face to valve stem concentricity. Powder metal seats typically have a smoother surface, requiring less machining effort. another trick that’s sometimes used to remove a hard seat is to insert a valve that’s somewhat smaller than the seat in the head and then. On a powder metal seat it is about 0.001˝. These tolerances are often called out. runout on a cast seat is typically seen at 0.003˝ to 0.005˝; And, at a microscopic level, cast seats can have a rougher surface, which increases friction and accelerates wear. The curves shown are typical of those available from valve manufacturers. engine valve stem runout tolerances are critical parameters that determine the longevity and performance of an engine. the percent of flow through the valve is plotted against valve stem position. when lobing is present in a valve stem, it will create runout in the valve head when the valve face is reground. This, in turn, may prevent the.
