Head removal?

Okay, so The front glow plug on the passengers side of my brother's truck is all kinds of stuck and not coming out. We've tried for quite sometime and to no avail. I have talked to several mechanics and ford service managers and it is clearly time to pull the head. After the quotes that I've recieved to do this job, I've decided that it is worth it to just do it ourselves. I would like to avoid pulling the motor if possible.

What I'm getting at I guess, is will it work to jack up the cab and get the clearance I need? I think someone said in another thread that they or someone they know has a 3" body lift and that gives them the clearance needed to get the head off. Is this true? What will I have to disconnecting or reroute in order to get the clearance. I may go the body lift route, or I may just jack up the cab and temporarily block it up.

Also, I'm guessing I'll need new head bolts, because they may have stretched. Is there anything I should be extra careful to lookout for?

Thanks a ton guys.

Oh Sorry, the truck is a 96, auto, ext. Cab 4x4, if that matters.

I dont jack up the cab. I usually just take the heater box off or u can work around it. Ive done it both ways. If u leave the box on, u will have to jack up that side of the engine a little to remove the injectors at the box. Its a pretty easy job. just time consuming. The last one I done I had about 8 hours in the whole job. I took two bolts and welded them into a "t" to screw in the head for lifting brackets. Makes the job a little easier. and as the head bolts go. Ive never seen a 7.3 head bolt stretch. They are not torque turn. Ihc says the check the bolts for stretching. they can be reused.

Sounds good. What about just using clevises(spelling?) to extract it, like you would use to remove a complete engine? Making t screws wouldn't be that hard eiter. What kind of seals need to be replaced for the injectors.
Thanks,

What year is his truck? I know on the '94-'97s there is no need to lift the cab or pull the blower box. You'll want to replace the external injector o-rings. While you have it this far it might not be a bad idea to get some head studs if he plans to do much with it performance wise.

Yeah, I was thinking head studs might not be a bad idea. He definitely wants a chip on it, and is thinking a set of injectors maybe later down the road. Its a 96, so that is good to hear that you don't have to jack it up. I've heard all kinds of different things, but it doesn't seem like with will be that hard. I've done heads before, but never a PSD. Anyways, we'll see how it goes.

So I have the hoist all hooked up to the head, all bolts removed (18), hoses, lines etc. Disconnected. But the head doesn't want to seperate from the block. Is there anything I'm missing here or has it just formed a seal from all the time its spent tightened down? Thanks guys,

Try prying on one corner of it to get the gasket to separate. That could be what's holding it up. You do have the exhaust manifold unbolted from the up pipe or removed from the head as well?

Yeah, the exhaust manifold is completely removed. I'm thinking its probably just a stuck gasket, but I wanted to make sure there wasn't something else I was overlooking.

Still having trouble freeing up this head, got any suggestions? I've tried prying, hoisting, tapping with a dead blow etc... The there any special way or place to hook the hoist to make this happen easier. Something seems wrong with this. with the hoist it just starts trying to lift the entire engine out. I've removed rockers, push rods, injectors, 18 head bolts, exhaust manifold. What else could it be, I've disconnected the fuel return line from the back of the head, the fuel and oil lines from the front.
What am I missing here guys, it shouldn't be this much force/trouble to get this head to break free.
thanks,
Sean

If it is an automatic the dipstick tube is bolted to the head. I can't believe it would hold you up though. Also does the front of engine accesory brackets bolt to the head? I have never pulled a head on a PSD before, just throwing out some ideas.
