  2. Remove the glow plugs. Refer to GLOW PLUG SYSTEM - 6.7L DIESEL .
  3. Remove the rocker arm assemblies for the affected cylinders. Refer to ROCKER ARM .
  4. Install the Dial Indicator Gauge with Holding Fixture so the needle tip of indicator is on top of the push rod.
  5. Rotate the crankshaft using a breaker bar and socket attached to the crankshaft pulley retaining bolt. Rotate the crankshaft until the base circle of the camshaft lobe is reached.
  6. Zero the Dial Indicator Gauge. Continue to rotate the crankshaft until the high lift point of the rocker arm is in the fully raised position (highest indicator reading).
  7. To check the accuracy of the original indicator reading, continue to rotate crankshaft until the base circle is reached. The indicator reading should be zero. If zero reading is not obtained, repeat the measurement.
  8. If the lift on any lobe is below specified service limits, install a new camshaft and valve tappets. Refer to Engine .
  9. Install the rocker arm assemblies. Refer to ROCKER ARM .
