Valve Guide by SBI®. 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 SBI valve guides are designed with an internal spiral groove to provide additional oil retention and reduce valve guide and valve wear.
