Is that a radial measurement? At what tolerance does a valve's inability to seal (with a film of a 'normal' oil) become problematic? Russ Smiley (an engineer, but not a machinist) Marlborough, CT The measurement is the distance between the rotor and casing. As to the other question, this is right at the borderline to using heavier oil. At about .006, I think a valve job is in the works. Maybe Walter can elaborate on this if he reads it.
