Engine knock on 2004 f150

Looking at buying a 2004 f150. It has a knock under the hood on the passenger side. Person said that was selling it that the knocking was normal on 2004 & 05's. Said it was the cam plate, wanted to know if this is really a problem that Ford had or is he just trying to pull one over on something that could be a major problem. thanks

    I have the same problem. I have had mine since the day I bought used. It sounds like a lifter. More of a tick than a knock. I havent tore into it yet to find problem but it runs great and I have put 20,000 on it.
