The valvetrain is the mechanical heart of your engine, and internal components like the camshaft and lifter are responsible for the precise synchronization of intake and exhaust cycles. As engines in Chevrolet, Ram, and Ford vehicles reach higher mileages, identifying subtle mechanical changes can prevent a total engine rebuild.

Step-by-Step Guide to Inspecting Camshafts & Lifters

1. Listen for Rhythmic Tapping

Monitor the top of the engine for a metallic clacking sound that increases in frequency with engine speed.

2. Inspect Valve Cover Interior

Remove the cover and look for metallic glitter in the oil.

3. Perform Visual Lobe Check

Rotate the engine by hand and inspect each lobe for scoring or flat spots that indicate the hardening has failed.

4. Measure Lobe Lift

Use a dial indicator to measure the lift of each lobe. any variation between cylinders signals a failing camshaft.

5. Check Lifter Plunger Movement

Press on the lifters when the valve is closed. A lifter that feels spongy has failed internally.

6. Inspect Cam Bearings

Check the bearing journals for deep scratches or discoloration from heat.

Other Key Engine Parts

Valve Covers: Protect the valvetrain and should be checked for warping or leaks during inspection.
Full Set Gaskets: The most cost-effective way to obtain all seals required for an engine top-end repair.
Cylinder Heads: The structural housing for the entire valvetrain; check for guide wear during cam replacement.
Timing Belts & Chains: These drive the camshaft; always inspect the timing drive when the engine is opened.
