  Q: How to Service and Repair Exhaust Valves and Intake Valves on Dodge Ram 1500?

  A:

  Before dealing with the valves and seats, you have to take out the cylinder heads. After that, pull out the Rocker Arms and Lash Adjusters and next, remove the Camshaft bearing caps and the camshaft. Place valve spring compressor Special Tool C-3422-B or C-3422-C into the area with the Special Tool 8519 Adapter, then if necessary, gently tap the top of the valve spring to free the locks holding the spring retainer in place. Lift out the two halves of the spring retainer lock with care, remembering how stretched the valve spring becomes. After using the spring compressor, disconnect the retainer and spring, paying attention to any sharp edges in the keeper grooves and then deal with any burrs on the valve stem. Since Valve Stem Seals are the same, you should remove one and label the valve for the proper installation method. Coat the valve stem with clean engine oil before gently inserting it into the cylinder head, seating the seal fully and checking that the garter spring isn't damaged. Install the spring and retainer after that and depress the spring with the compressor to put the valve spring retainers in place one by one. Remove the valve spring compressor after making sure the retainer halves and spring are sitting securely in place. Lubricate the camshaft journal with clear engine oil, fit the left camshaft at 11 O'clock and the right camshaft at 12 O'clock with their sprocket dowels and place the camshaft bearing caps in their positions. Fasten the camshaft bearing cap bolts, turning them until they are tightened to 9 - 13 Nm (100 inch lbs.) just a half-turn after each application. After that, put the hydraulic lash adjusters and rocker arms into place.

  Q: How Can Exhaust Valves and Intake Valves Be Reworked When Worn or Burned, and What Are the Key Measurements for Proper Refacing on Dodge Ram 1500?

  A:

  The cylinder head should only be replaced if you cannot maintain the proper angle or seat width when reworking the worn or burned valves and seats. Reinstalling stones in refaced valves requires getting the proper size valve guide pilot to ensure a proper and full surface. First, use a correct dial indicator to check the center of the valve seat and make sure total run out does not pass 0.051 mm (0.002 inch). The width of the intake seat should be between 0.0689 - 0.0928 inch (1.75 - 2.36 mm) and the exhaust seat must be between 0.0673 - 0.0911 inch (1.71 - 2.32 mm). Upon refacing, the valve spring installed height for both intake and exhaust should remain under 40.74 mm (1.6039 inch). The angle between the valve seat and valve face should always be 44.5 - 45°.
