You generally do
not have to remove the engine to replace the camshaft in most vehicles. However, it depends heavily on the vehicle's design and the specific engine. Some engines allow camshaft replacement with the engine in the vehicle, while others require engine removal for easier access. The level of difficulty also varies greatly.
Consult a repair manual specific to your vehicle's make, model, and year to determine the correct procedure. Attempting this repair without the proper knowledge and tools can lead to significant damage.
