My father-in-law gave us an 85 Ford van 302 that he bought new. 100,000 miles and he never changed the plugs. Any suggestions for getting them out without breaking them off?

Tighten them just enough so they move, then remove them. Sounds strange but it works. :yes:

Those will be iron heads, so you shouldn't have any problems with breaking them. I'd be concerned with the plug wire heads, though, so don't do it without another mode of transportation to get to an auto parts store.

I'm changing the wires, cap and rotor, too. Parts store is 1/2 block from here. And I also have 3 other vehicles.

You could first measure the resistance of the wires. The spec's could be 25k, max, like for my Civic, or some other value. Wire resistance values for American cars are all over the map. I had a Dodge where they had a per foot spec and a max value spec (50k).

With my miss problem I returned my rotor and cap because it turned out new plugs solved it. My wires checked good.

I agree with the warm the engine up. Cast iron moves with cold and heat. The heads will expand when warm/hot helping to release the grip on the plug threads. yes on tighten than loosen. I like PB also. wd40 to me anyway is more myth than real use

Finally got a chance to work on it. They weren't even tight. They just screwed right out.
