First open valve locks to take out valve spring and cap and lastly extract valve guide seal. Check valve spring condition and replace it with fresh components if it shows signs of wear. Put the new seal onto the valve stem until it sits completely into the valve guide position. Press your fingers over the valve guide seal to put it in place on the valve guide using the j 42863 tool. Use the valve spring compressor j 38606 to once again compress the valve spring. Place the valve spring and cap on their respective positions first before fixing the valve locks securely.
