  Q: How to service and repair the Exhaust Valve and Intake Valve on Dodge Ram 2500 Van?

  A:

  The first step to work on the valve is to take out the cylinder head. Wrap the valve springs with the MD-998772A and 6716A adaptor, compress them using the tool and then unscrew the valve retaining locks, remove the valve spring retainers, valve stem seals and valve springs. It is important to remove all burrs from the valve stem grooves so the valve guides remain safe and to identify each valve so it is installed properly later. Clean the valves very well, removing and replacing any that are damaged with cracks, burns or warping. Get rid of carbon and varnish inside the valve guides using a cleaner you can trust. Take note of the stem-to-valve gap on the bent-tip gauge. If it's more than 0.051 mm (0.002 inch), fit a new valve. Oil the valve stems and slide them into the appropriate holes of the cylinder head. When you discover the valves or seats have been ground, check the valve height and alter the cylinder head when the valve is too tall. Install new seals on each valve guide and then add the valve springs and their retainers. Put the Valve Spring Compressor Tool MD-998772A and the adapter 6716A together, press in the valve springs, secure the locks and use the tool handle to let go. If the valves and buttons have been ground, measure the spring's installed height with spring, seat against seat or top of spacer to its retainer. Place a spacer in the head counterbore if the spring's height surpasses 42.86 mm (1-11/16 inches) to return the spring height to 41.27 to 42.86 mm (1-5/8 to 1-11/16 inch). The final step is to fix the cylinder head in place.
