  Q: How to replace lifters in a engine on Nissan 240sx?

  A: Disconnect the negative battery cable. Remove the Cylinder Head, if required. Remove the rocker arms and shafts. Withdraw the lash adjusters from the head or from the bore in the rocker. Tag each lash adjuster to the corresponding cylinder head opening or rocker. If the lash adjuster is installed in the rocker, remove the snapring first. Be careful not to bend the snapring during removal. Install the lash adjusters in their original locations. Use new lash adjuster snaprings as needed. New lash adjusters should be soaked in a bath of clean engine oil prior to installation to remove the air. Install the rocker arms and shafts. Install the cylinder head and leave the valve cover off. Check the lash adjusters for proper operation by pushing hard on each lash adjuster with fingertip pressure. If the lash adjuster moves more than 0.04 in. (1mm), air may be inside it. Make sure the rocker arm is not on the cam lobe when making this check. If there was air in the lash adjusters, bleed the air by running the engine at 1000 rpm for 10 minutes. All lash adjusters used on Datsun/Nissan engine applications are not overhauled--If a problem (noise or wear) exists replace the lash adjuster. When replacing a lash adjuster assembly it is recommended the entire set of lash adjusters be replaced.
