Q:
How should the measurement for cam lobe lift be taken, and why is it important for the 2003 Chevrolet Blazer? Posted by Customer
A:
The measurement for cam lobe lift should be taken by slowly turning the engine until the pushrod is at its lowest point (base circle of the camshaft lobe), then zeroing the dial indicator. The crankshaft is then rotated in the normal direction until the indicator needle reaches its peak and begins moving in the opposite direction, marking maximum cam lobe lift. This measurement is important to assess camshaft wear.
