  Q: How to Maintain and Repair a Rocker Arm Assembly on Dodge Neon?

  A:

  Before you remove the components, first take off the cylinder head cover and spot the rocker arm shaft assemblies. Free the fasteners that hold the rocker arm shafts onto the cylinder head and then take them off. Note where each rocker arm spacer and retainer goes and use a socket wrench to take out the bolts holding the rocker arm to the shaft. Take the spacers and rocker arms off the shaft and make sure you remember where you put them. Makes sure the rocker arms look good, without scoring or damage and swap them as needed. See if the mount points on the shafts have signs of wear or have become loose. If so, change them out as required. The rocker arm shaft is a duct for lubricating oil, so check for clogging and clean the oil holes if they are dirty. Before fitting the rocker arm shafts, move the Crankshaft so it is 3 notches from top dead center. Rub a lubricant on the rocker arms and spacers, then put them back on the shafts as they were originally. Be sure to have the adjusters full of oil or almost full, so the plungers don't move more than half their range while being pressed. If there is too much up and down movement of the plunger, put the rocker arm assembly in fresh engine oil and pump it until the Lash Adjuster movement stops; if travel still remains, replace the assembly. Set the rocker arm and shaft pieces in their positions, with the Notch located in the rocker arm shafts aimed up and close to the timing belt side of the engine and place the retainers back on the exhaust and intake shafts where they previously were. Prevent the plastic spacers from blocking the spark plug tubes by twisting them to the proper angle instead of forcing down the intake rocker arm shaft assembly. Make sure the swivel feet for the hydraulic lash adjuster are in the right location and then tighten the bolts to 28 Nm (250 inch lbs.) as outlined. In the end, place the cylinder head cover onto the engine.

  Q: How to Service a Rocker Arm Assembly on Dodge Neon?

  A:

  Begin by taking off the cylinder head cover and then find the rocker arm shaft assemblies before moving onto removal. Loose the holders on the cylinder head and take out the rocker arm shaft assemblies. Remember to keep the rocker arm spacers and retainers safe and after that, use a wrench to remove the bolts that connect each rocker arm assembly to the shaft. Remove the rocker arms and spacers from the shaft and try to keep them where they were for the next step. Inspect the rocker arms for wear and damage and change them if they are bad. Examine the mounting points for any wear or harm; have a replacement if you notice anything wrong. Because the rocker arm shaft is hollow, it functions as an oil duct. You should ensure any oil holes are open and clean with a small wire as necessary. Make sure the crank is turned to just 3 notches before reaching top dead center before you add the rocker arm shafts. First, lubricate both the rocker arms and spacers and then put them back on the shafts in their initial placements. Place the rocker arm or hydraulic lash adjuster assembly, making certain the adjusters contain oil by showing up to 2mm of uncovered plunger length when pressed. If the rocker arm assembly travels too much with the plunger, cover it with clean engine oil and use the plunger until lash adjuster travel is overcome. If this doesn't happen, change the rocker arm assembly. Attach the rocker arm and shaft parts so the Notch is facing up and close to the Timing Belt side and correctly place the retainers on the exhaust and intake shafts where they were before. Be sure to place the plastic spacers under the intake rocker arm shaft so as not to block the spark plug tubes; if they get in the way, rotate them to the right angle instead of shoving the assembly down. Screw the bolts to 28 Nm exactly (250 in. lbs.), following the proper arrangement, before mounting the cylinder head cover.
