  Q: How to remove and replace the Valve Stem Seal, spring, and retainer on Lincoln MKS?

  A:

  Begin cleaning the area around the components before removing the valve spring, retainer, and seal since foreign materials that enter the oil or coolant pathways may cause engine failure. Begin by taking out the valve tappets which serve the targeted cylinder. The crankshaft needs to be turned so that the piston which will receive service reaches maximum upward position. The valve should be supported before any air pressure removal since otherwise it could drop into the cylinder which demands cylinder head removal. Before reinstalling the components, mark them for correct placement when returned to their original positions. Compress air into the cylinder until Valve Spring Compressors can efficiently take out the keys, retainer, and spring. Ensure to take off and toss away the valve stem seal as a final step.
