Kkt valve guide has incorporated over 25 years of foundry and machining technology into each and every guide. Valve guides are manufactured with specified tolerances and can be installed directly into the cylinder head guide bore without additional work. Considering requirements of emission control engines, this presents unique challenges in repairing today's cylinder head. Almost all OEM engines incorporate positive valve stem seals and chrome plated valves to reduce exhaust emissions. This fact, in relationship to higher operating temperatures, has made valve guide lubrication a prerequisite. Today engine valve guides are composed from complex alloys combining heat treatments and wear coatings to ensure proper lubrication during operations. Many kkt valve guides are designed with an internal spiral groove to provide additional oil retention and reduce valve guide and valve wear.
