according to the engine service manual on this 6EM truck there is no valve adjustment. It has lash adjusters in the rocker arms that are preset to deal with any valve lash. Basically they are hydraulic like was mentioned.
When dealing with these during dissassembly or reassembly they should be kept clean free from any dirt. Use Diesel fuel to clean them according to the manual.
Thanks jeremy, I was thinking of the smaller motors. It has hydraulic adjusters in the rockers.
the number is stamped on the side of the block, no valve lash adjustment needed.
