* Wear and tear: Over time, the camshaft can wear down, especially if the engine isn't properly maintained.
* Manufacturing defects: A faulty camshaft from the factory is a possibility, though rare.
* Lubrication problems: Insufficient or contaminated engine oil can lead to premature wear and even breakage.
* Over-revving: Pushing the engine beyond its RPM limits can stress the camshaft and other components.
* External damage: Something striking the engine could potentially damage the camshaft.
While less likely than other engine failures, a broken camshaft is a serious issue requiring engine repair or replacement.
