  Q: How to service and repair an Intake Valve and Exhaust Valve on Ford Freestyle?

  A: The procedure for valve repair begins with diameter measurements along the specified points of each valve stem followed by a specification check. Out-of-spec measurements require installing new components. Check the valve regions starting with the stem end for grooves as well as scoring and moving to inspect the valve face and edge for pits and scores followed by examining the valve head for signs of burning and evaluation of warpage and erosion and cracking. The inspection should complete with checking the valve margin for wear. The inspection process requires a check on valve seat and valve head alignment and valve clearance and validation of the valve angles plus margin width to match specifications following valve or valve seat grinding. The inspection should check for any abnormalities on the valve face and seat. Installing a new cylinder head assembly is necessary in case abnormalities are detected.
