Proper protection of the camshaft from corrosion is very important. Corrosion will start in as little as one hour after the camshaft has been cleaned. When the camshaft will not be inspected for one hour or less the camshaft should be coated with a rust or corrosion inhibitor or coated with clean engine oil. The camshaft should be individually wrapped in order to prevent contamination, and the camshaft should be stored in a protected area in order to avoid damage. See Illustration 36. When the camshaft will not be inspected in two days or more the camshaft should be coated with a rust or corrosion inhibitor or coated with clean engine oil and the camshaft should be individually wrapped. The wrapped camshaft should be placed in a container which is clean and structurally solid. The container should be covered or wrapped in plastic in order to prevent damage and contamination to the camshaft. See Illustration 37.See Table 4 for recommended rust inhibitors.
