Thread: Valve guide repair

Tweet

Most times that I have seen a really really bad guide, the seat and valve were pounded worn really wide---If they aren't worn out like that, try putting some positive seals on the stems to cut down on the oil consumption

The reason most shy away from the oversized valve stems ,is because most of the time this work is being done to enhance performance ,filling the intake and exaust ports with huge valve stems cuts down on flow and performance.
In a mild street build ,oversize stems would not hurt that much in the performance department.
