    Q:
    How do you determine the extent of cam lobe wear and the condition of the Lash Adjuster before removing the camshaft for the 1995 Chevrolet Blazer? Posted by Sonja H.
    A:
    To determine the extent of cam lobe wear, position the number one piston at TDC on the compression stroke, remove the valve cover, and loosen the rocker arm nuts to access the pushrods. Then, mount a dial indicator on the engine, position the plunger against the top of the first pushrod, and zero the dial indicator. Slowly turn the crankshaft in the normal direction of rotation until the indicator needle stops and moves in the opposite direction, indicating maximum cam lobe lift. Record this figure and repeat the check for each valve. You can Select Your Vehicle to see complete installation and repair tips.

    Q:
    What should be checked, including the Lash Adjuster, before removing the camshaft for the 2005 Chevrolet Express? Posted by Courtney W.
    A:
    Before removing the camshaft, check the lobe lift and ensure that if a new camshaft is being installed, new lifters must also be used. You can Select Your Vehicle to see complete installation and repair tips.
