Valve guide
During repair work on the cylinder head with leaking valves or valve replacement treatment and the valve seat is not enough. It is necessary to check the wear of valve guides. It is especially important to check the engine with a long service life. Worn valve guides do not provide the centricity of the valve seat and leads to increased oil consumption. If the wear is too high, replace the valve guides (job for the garage).
