ABSTRACT:
A cylindrical valve guide having a roughened external surface texture from about 50 to about 100 microinches permits effective amounts of lubricating oil to become trapped or contained by such roughened external surface and thereby facilitates subsequent press fitting of the valve guide into an internal combustion engine. Centerless grinding constitutes a preferred method of achieving the surface texture of the invention.
