2005 Ford Explorer Exhaust Valve Parts Q&A

• Q: How to service and repair the exhaust valve and intake valve on 2005 Ford Explorer?

  A: The repairs on valve and valve seat require initial diameter measurements of intake and exhaust valve stems at their designated points. If these measurements are outside specified limits the technician should replace faulty components. Check for grooves or scoring at the end of the stem together with pits along with scores on the valve face and edge. Also examine the valve head for burning presence followed by evaluation of erosion and warpage and cracking. Assess the valve margin for wear. When grinding valves or valve seats you should check valve clearance and head and seat condition alongside verifying angles and margin width specifications. You should take measurements of the valve seat width following which necessary grinding steps should be performed according to specifications and then check both the intake and exhaust valve seat widths. The valve spring installed length should be rechecked after grinding then valve springs should be shimmed to reach the correct installed length. The last check involves using the Valve Seat Runout Gauge to measure valve seat runout.
