single overhead cam or dual overhead cam?

i have a 2000 zx3 and i'm wondering how to tell if i have a AOHC or a DOHC...can anyone help me out?

Do Your Plugs Go Inthe Side Of Head By The Exhaust Or Do They Go Through The Valve Cover..if They Go In The Valve Cover You Have A Dohc

My 00 ZX3 has a DOHC motor...it should be fairly simple to tell; just pop the hood and see if their is one or two camshafts running underneath the valve cover. Ford also calls their DOHC of that generation the Zetec.

Hey, simple answer for a simple question, if youve got the Duratec or Zetec Focuz engine, you have got DOHC, if your running the Split Port focus, your SOHC
