Cylinder head removal

DeltaRed · Jan 31, 2020

I have a 92 Ford F-150 with 300 fuel injected 6. It Russia a freeze plug in the back of the head. I am going to have to pull the head to repair it. However it looks like a major deal with the fuel injection system on top. Any suggestions? The pickup has 250 plus thousand miles on it it is a good little farm pickup. I hate to junk it. I don't want to spend a tremendous amount of money overhauling engine as well.

It's not as bad as it looks.

Take it one piece at a time. Once the major components are out of the way, it begins to look like something doable.

I think there are some small plugs along the sides of the head, and with everything out of the way the ones in the block will also be accessible.

How much room is back there? If you can manage to pry the old one out, one of these can be pushed in, (instead of driven in), tightened up, and will give a permanent repair.

I would be tempted to cut a hole in the firewall, Of course I an stingy and do some crude jobs for my self like cut holes and make patches with pop rivets.

Moonlite37,

I, too, cut holes where necessary. If I need to, I patch them with rivets or screws for a future repair. Glad to see someone else does things like that.

yup, i like the idea of cutting a hole in the fire wall. you may need to remove some heater ductwork, but easier than pulling the head or pulling the motor out.

Hello deltared,

I too would cut a hole, easy access then a quick fix. If you cut it in one piece, you can put it back on with a couple of straps, and some silicone,

yep, cut a hole in the firewall. we did that once in the garage on a fairly new truck in the 1970's, 460 I think it was. then put a rubber plug in it.

Other ten ten Bizzllilon wires and hoses . It's not that big a deal . Looks worse then it is . Atleast it is a 6 and not a stuffed in big block . I would say that one from start to finish is a 6 to 8 flat beer rate job . NOW Maybe , just maybe if you had say three four inches of room between the head and fire wall and you could roll the old soft plug out with a little barn yard engineering you could make up a MINI press with say a 5/8th bolt a plug to fit the soft plug and a plate of steel as a back up to set agaist the fire wall to push against oR CLEAN THE HOLE OUT WELL AND DRY IT AND USE A RUBBER EXPANDING PLUG . SORRY NOT THERE TO SEE FOR MYSELF . SOME TIMES WE MUST DRINK THE SITUATION OVER AND THINK FIRST BEFORE WE ACT.

You could get one of those rubber soft plugs that expand when you tighten up a bolt.

well wait, that copper one might be better.

I agree with Steve on using one of those copper expandable ones, I used them in the past in tight spots and they held fine. A thin film of RTV or your preferred sealer smeared inside the hole before install helps assure a good seal. Kind of a hack method but I have seen the old plug just driven in the hole and left there. That would not be my first recommendation. I also agree with others on making a hole in the body for access if it can save disassembly. Best of luck!
