Does a Camshaft Increase Horsepower?

Although a vehicle can sometimes still be driven with a damaged camshaft, it is extremely risky and not recommended to continue driving.

The camshaft is responsible for controlling the opening and closing of the valves. Once damaged, the intake and exhaust timing will be out of sync, leading to power loss, increased fuel consumption, engine vibration, and even stalling.

Continuing to drive with a damaged camshaft will not only exacerbate the wear on the camshaft itself, but may also damage components such as valves, lifters, and rocker arms. In severe cases, it can even cause the piston to collide with the valves, resulting in major engine failure.

Therefore, if you notice abnormal noise, a significant drop in power, or the engine warning light illuminates, you should immediately stop the vehicle and have it inspected and repaired, replacing the damaged camshaft to prevent minor problems from escalating into major overhaul issues.
