Video: 10 Reasons For Camshaft And Valvetrain Failure From COMP Cams
By BRIAN WAGNER MARCH 07, 2017
A big camshaft creates a symphony of sound and horsepower that every performance enthusiast and racer loves to hear. That chop and lope isn’t something that can be achieved without thought, though, as upgrading a cam requires other items to be addressed or disaster can strike. This video from COMP Cams covers 10 of the biggest reasons that awesome-sounding camshaft can fail you if you’re not careful.
In the valvetrain, the camshaft is the brains and backbone of the operation, ensuring everything opens and closes as it needs and is supposed to. So, not having control of the valvetrain can cause massive damage to its parts, including the cam. According to COMP, it’s critical to make sure you have the correct parts for your application and that they’re strong enough to take the abuse you plan on dealing out.
Another thing that can cause damage is ignition cut rev limiters. While hitting the rev limiter can sound really cool, it’s not great for the valvetrain. The added pressure from the extra fuel being burnt in the combustion chamber puts added stress on the valvetrain that it wasn’t designed for and will cause damage.
Make sure you watch this entire video from COMP Cams that covers all 10 of the different items that can cause camshaft and valvetrain failure in your modified engine.

if the lifter base is well worn you can bet the farm the cam lobe is most likely also worn, and you'll need a lifter removal tool to pull the damage lifters up out through the blocks lifter bores
if the lifters are very badly damaged, it may be best to remove the push rods , use strong magnets to hold the lifters in place and remove the cam, then slide a section of pvc pipe with the upper half removed and let each individual lifter fall into the pipe and be removed one at a time and be removed rather than risk damaging the lifter bore walls, dragging the damaged lifters out through the blocks lifter bores
