Valve cover removal 99 ford van - 1999 Ford Econoline

SOURCE: how to remove the valve cover to replace gasket

What kind of engine? If it's a 3.0L Vulcan, you have to take off the upper and lower intake manifolds and you'll be able to take the valve covers off. There's a bunch to take off before you get to that point. The EGR Valve, Throttle body assembly, ignition coil pack, etc. Make sure you relieve the fuel system pressure (it might be behind the right side well cover of your trunk- disconnect that connection), and take off the negative battery terminal before begining work.
