    Q:
    How do you determine the extent of cam lobe wear and the condition of the Lash Adjuster before removing the camshaft for the 1989 Chevrolet C1500? Posted by Jeanette A.
    A:
    To determine cam lobe wear, you should first position the number one piston at TDC on the compression stroke. Then, loosen the rocker arm nuts and pivot the rocker arms sideways. Afterward, mount a dial indicator on the engine and position the plunger against the top of the first pushrod. Zero the dial indicator and slowly turn the crankshaft in the normal direction of rotation until the indicator needle stops and begins to move in the opposite direction. Record this figure and repeat the check for each valve. You can Select Your Vehicle to see complete installation and repair tips.
