Someone asked me recently about the definition of a vavle guide. I thought I'd share it with all.

The definition of a valve guide is as follows:
Valve Guide: The cylindrical hole which is located in the cylinder head or block through which the stem of the poppet valve passes. It is designed to keep the valve in proper alignment. It also serves as a bearing surface. Some guides are pressed into place and others are merely drilled in the block or in the head metal.
