t  Feeler gauge
t  Wooden or plastic wedge
  Note
t  Always replace defective bucket tappets complete (cannot be adjusted or repaired).

Test sequence
–  Start engine and allow to run until the radiator fan has cut in.
–  Increase speed to 2500 rpm for 2 minutes.
If the bucket tappets are still loud, check the faulty tappet as follows:
–  Remove top part of intake manifold and cylinder head cover → Chapter.
–  Turn the crankshaft clockwise until the cam of the bucket tappet to be tested is positioned on top.
   
–  Press the bucket tappet down lightly using a wooden or plastic wedge.
If a 0.20 mm feeler gauge can be inserted between the camshaft and the bucket tappet, the tappet must be replaced:
–  Replace tappet.
  Note
After installing new bucket tappets, the engine must not be started for about 30 minutes. The hydraulic clearance compensation elements must settle (otherwise valves would strike the pistons).
