    I'm having a hard time replacing the spark plugs on my 17 ranchero 500 with Cleveland engine. Any help appreciated.

    What's the difficulty you're having?

    Use a spark plug socket, they are not regular sockets; you can spot them by the rubber insert inside, and turn them out counterclockwise. They may be a bit stiff.

    Do what Ribald says; seriously, use the correct socket. The right socket type will also make replacing them easier. I'd just add that a flexible socket drive handle (has a vertical joint near the socket) can make getting to it easier.

    I replaced mine when I updated my headers. If you take off the exhaust manifolds, it's very easy to get to the plugs. If you don't have a spark plug socket, put a little electrical tape on the inside of the socket.

    Spark plug socket is much cheaper than exhaust manifold gaskets and and a whole lot easier. Lol

    Why take manifold off are you changing them from the bottom. ford-cleveland-tech-351-two-barrel-illustration.jpg

    Back in the 90's my wife fell in love with a Chevy minivan, so I got it for her.
    Had it less than a year, one of the spark plugs could only be changed from underneath with your arm snaked up against the firewall, doing the job by brail one handed.

    If plugs are stuck soak with good penetrateing oil like PB blaster.
    Wd40 is not a good penetrateing oil.
    Warm up motor a little before soaking not smoking hot. 2 mins is fine. If you can get to turn a little respray and re tighten then work back and forth. This will work the oil down the threads after awhile they will come out.

    I seem to remember my Dad having a big-motor LTD or Torino in the 70's, and I believe you had to loosen one of the motor mounts to get to a plug or two; does that sound familiar?

    The windsor motor does have plugs hid by the exhaust so that could be possible.
    Most ford V8 engines have plugs above the exhaust manifold

    The Windsor has the exhaust manifold below the plugs, like the Cleveland.

    There is a Ford engine that came with a manifold that went over the plugs, but it is an old school one that is eluding me at the moment.
