  Q: How to Service and Repair Exhaust Valve and Intake Valves on Dodge Sprinter 3500?

  A:

  To deal with the valve, take the engine cylinder head off the cylinder block first. Make sure to use the Valve Spring Compressor Tool to compress every valve spring, before you remove the valve locks, retainers and springs. Polish the outside top of the valve stem, taking special care of the area where the locks fit, with a pebble or fine stone and afterward, remove the valves, keeping them in a holder in the same order as before. Thoroughly clean all carbon deposits in the combustion chambers, valve ports, valve stems, valve stem guides and head and eliminate all waste and gasket material from the engine cylinder head machined gasket surface. Look for cracks or damage in the combustion chambers, valve ports, exhaust seat and at the gasket surface near every coolant passage, plus burn, cracks or warping on the valve heads and scuffs or bends on the valve stems. Look at the height of the valve spring. Refacing the seat means using a size guide in the bore, dressing the seat to the proper angle with a high-quality stone and using tapered stones to get the correct seat width. Check that the heights for Measurement A are 16.50 to 17.00 mm and for Measurement B are 14.50 to 15.00 mm. The valve guide internal diameter should measure 6.0 to 6.012 mm (0.2362 to 0.2366 in.). The valve stem diameters are intake 5.952 to 5.97 mm (0.2343 to 0.2350 in.) and exhaust 5. Reduce the diameter of the valve stem from the inner diameter of the valve guide to compute the valve stem clearance-the proper range for this difference is 0.03-0.06 mm (.0011-.0023 in.) for the inlet valve stem and 0.04-0.07 mm (.0015-.0027 in.) for the exhaust valve stem. If the clearance between the valve stem and valve guide is greater than allowed, new replacement valve guides should be put in.
