  A:

  New and OEM rebuilt cylinder heads are now obtainable for almost all engines in the dealerships as well as auto parts stores making it easier and cheaper for those who intend performing as home mechanics to acquire replacement instead of taking the time and effort to disassemble, examine and then recondition the heads. Restructuring entails the removal of intake and exhaust valves and some related components such that each part is marked or placed in a separate area for reassembly. Valves must be properly marked and properly restacked to its original orientation while keepers, retainers and springs my be squished out of its compressed shape. When a valve binds, then there could be some need to deburr the area surrounding the keeper groove area. Following the removal and sorting of the valves the head should be cleaned, as should the rest of the engine should one be undertaking an engine rebuild. Cleaning has to do with removal of gasket material, removing scales and coolants' passages, and the use of wire brush and tap for threaded hole areas. The threads of the rocker arm pivot stud should also be cleaned and all parts must be dried, and one has to be careful when using alkaline decarbonizing agents. Every valve needs to be checked for signs of wear, distortion and cracking; valve springs require check for signs of wear or measured to the recommended length. The conditions of the valve seats and guides should also be examined and the damaged or worn parts should be adopted. In the 4-cylinder engines, cam followers will need cleaning with added check on wear and tear, V6 engines need checking on pits, wear, and cracks on the rocker arm manufactured components. If, after the inspection of the components, it is noticed that they are worn out, then assembly of the valves back in the cylinder head has to be undertaken; and then recommendations for valve servicing should be provided.
