Valve Guide: Service and Repair
NOTE: A valve stem that has excessive scoring or wear must be replaced. A valve guide that is worn and has excessive stem-to-guide clearance should
be sleeved to obtain the proper clearance.
1. Inspect the valve stems for excessive scoring, wear or warpage.
2. Measure the valve stem-to-guide clearance.
^
Excessive valve stem-to guide clearance may cause a noisy valve train, premature valve stem oil seal wear, component damage, and/or
excessive engine oil consumption.
^
Insufficient valve stem-to-guide clearance will result in noisy or sticking valves. Valves that are too tight may disturb engine smoothness or
lead to component damage.
NOTE: Carefully follow the manufacturers instructions when using valve guide reamers, sleeves, and installers.
