Place cylinder head onto the supports (1).

Fig 4: Identifying Cylinder Head Supports
Coat the outside of valve guide (5) with oil.
Position the valve guide (5) and knock into the cylinder head as far as the stop (arrow) of the insertion drift (3). Check the secure seating of the valve guide (5). The installation depth of the valve guide (5) is set by the drift punch (3).

Fig 5: Identifying Valve Guide
Check the valve guide (5) with the feeler gauge (4). The side of the feeler gauge (4) marked with '0' must be inserted completely into the valve guide (5). The valve guide (5) must be replaced if the feeler gauge (4) cannot be inserted completely. The valve guide (5) is made of powdered metal, so reaming is not possible.
