When it comes to modern internal combustion engines, there are two types that dominate the industry: pushrod and overhead camshaft (OHC). While pushrod engines were the stars of the show for many ...

Your car's camshaft — or camshafts if your vehicle has a DOHC engine — is a vital component that plays a critical role in the internal combustion process. Its job is to synchronize the opening and ...
