    Q:
    How should the Camshaft be inspected after removal for the 2007 Chevrolet Colorado? Posted by Vailele P.
    A:
    After cleaning the camshaft, inspect the bearing journals for wear and damage, and measure them with a micrometer to check for excessive wear or out-of-round conditions. Check the camshaft lobes for discoloration, score marks, and uneven wear; if they are in good condition, the camshaft can be reused.
