  A: The work requires these specific tools for Valve Stem Oil Seal service: valve spring compressor adapter (EN-47823), spark plug port adapter (J 22794), and valve spring compressor (J 5892-D). Before you start rotate the engine to put the piston at top dead center position so that the valve remains above the cylinder space. Before taking out the Spark Plug clean its seat area with a brush.

Pack the valve spring gently by working the valve spring compressor (J 5892-D) alongside the valve spring compressor adapter (EN-47823). Take out valve cap keys, valve springs, valve cap, and valve train oil seal in this order. Install the appropriate black and brown valve stem oil seals while lubricating the valve stem with engine oil.
