Description
Overview:
This Genuine Kohler inlet valve seal (OEM No. 17 032 40-S) controls oil flow around the inlet valve stem to prevent oil leaks and maintain stable intake vacuum and compression. It is used on Kohler CH series single-cylinder engines commonly found in construction and garden machinery. Made with an oil- and heat-resistant elastomer bonded to a rigid metal shell, it provides a secure, positive seal on the valve guide. Suitable for routine maintenance or repairs on engines such as the CH245 and CH255, it helps reduce oil consumption, smoke, and plug fouling while supporting reliable starting and smooth running. Designed as a direct replacement for the original part, it restores factory fit and function without modification.
