What is a cam, what does it do and how much can I expect to pay for one? If someone could provide a link, I'd be grateful!
a cam is what turns to open and close your valves located on the top of your engine below the valve cover and on top of the head lol. assuming you have a dohc zetec motor, you have two cams one for intake valves and the other for exhaust valves.

check this video out of how a dohc engine works its very interesting
