  Q: What Are the Key Differences in Servicing Exhaust Valves and Intake Valves on Dodge Intrepid?

  A:

  Before working on the valve, remove the cylinder head and use Special Tool C-3422-B, Valve Spring Compressor, to compress the springs. Remove both locking mechanisms for the valve, as well as the valve springs and spring seat/stem seals and their retainer. Remove any rough edges from the valve stem locking rods, identify each valve and put them back where they originally were to avoid problems. Before installing the valves, cover the stems with clean engine oil and set them into the head. When valves are reground, compare the tip of the valve with the specs; intake should be 47.59 mm (1.8737 inch) and exhaust should be no more than 49.14 mm (1.9347 inch). Adjust the valve tip by grinding it as much as needed so it meets the above requirements, measuring from the head of the cylinder to the top of the valve stem. Then, place the rubber seal/spring seat assembly down onto all the valve guides, keeping the middle rubber seal centered and the garter spring undamaged up top. Place the valve springs and valve retainers onto the engine. Compress the valve springs, set the locks in place and after that release the compressor. Should any of the valves be reground, consistently check the installed height by measuring from the spring seat's top to the spring retainer's base. If the height is out of specification (more than 38.75 mm), fit a 0.762 mm spacer in the head counterbore under the spring seat to reach the right size.

  Q: How to Service and Repair Exhaust Valve and Intake Valves on Dodge Intrepid?

  A:

  The cylinder head(s) should be removed before the valve spring of the valve is taken out. Ensure that whatever tools you use to remove the valves don't leave any burrs inside the valve stem lock grooves and thus harm the valve guides. As you take out each valve, check its type so you put it back where it belongs. For assembly, cover the valve stems with clean oil and insert them straight into the cylinder head. Should the valves or seats have been reground, double-check their tip heights. The intake valve may be no bigger than 47.59 mm (1.8737 inch) and the exhaust no bigger than 49.14 mm (1.9347 inch). Should the valve tip height be beyond the specifications, use a grinder to make the tip smaller and follow these measurements, using the surface of the head and upper most part of the stem as the reference. After that, attach the valve spring.
