Ticking Clicking Noise Coming From Your Engine Diagnosing Collapsed Lifters

Created on: 2021-11-20

Andy diagnoses a top end clicking ticking noise in our Chevy Avalanche! Andy locates the clicking noise to the top driver side of the 5.3L V8 engine, and discovers an intermittent misfire in cylinder 1. After removing the valve cover, he finds a very loose rocker, the source of our noise. He determines the rocker is loose because its lifter has collapsed, meaning it's not pushing up on the rocker when activated by the camshaft. The fault is in the AFM (active fuel management) lifter.
