• Q: How Can Exhaust Valve and Intake Valve Seats Be Reworked to Ensure Proper Refacing on 2006 Dodge Ram 2500?

  A: If valve seats are wearing or burned, the valve seat area can be fixed when the correct factors are kept; in any other case, a new cylinder head is necessary. Reseating stones correctly means putting the right size valve guide pilot under the valve. To start, use dial indicator to check the valve seat center, making sure the run out does not surpass 0.051 mm (0.002 inch). Place a tiny dab of Prussian blue on the valve seat, put the valve into position in the cylinder head and rotate the valve under light pressure. After you take the valve out, look at the valve face. If the blue transfers below the top edge, adjust the valve seat using a 15 degree stone and if it transfers to the valve bottom, use a 65 degree stone to raise the seat. The width for both the intake and exhaust seats in a properly set-up engine should range from 1.018 to 1.62 mm (0.464 inch) and from 1.48 to 1.92 mm (0.058 - 0.075 inch), respectively. After finishing the valve job, make sure that each valve spring is held down below 46.0 mm (equivalent to 1.81"). It is required that the valve seat form an angle of 44.5 to 45.0 degrees and the valve face should be angled between 45.0 and 45.5 degrees.
