Hey all,

I just want to get the head off and 7 stupid bolts won't let me. When facing the engine, the bolts on the right crack with no trouble. The bolts on the left how ever don't want to move. I did find a thread on here about head bolts but nothing has worked. I would like to keep the head so taking an angle grinder to it isn't and option (unless all other options are exhausted).

What I've done:
I have a breaker bar and extension
Been using a 14mm single hex socket
Soaked them in WD40
Tapped them on the top with a hammer
retightened all the other bolts to take the pressure off

Only thing that keeps happening is the socket either cracks (I'm not using cheap sockets either) or is the socket doesn't crack then it just rounds off the top. WHAT THE HELL AM I MEANT TO DO!!!!

Get a thin drill bit and drill down the center of the bolt, then pick up some easy-outs made for metal at your local hardware store.

Twist the easy outs into the bolt and hopefully that should get them.

Did you undo the bolts in a spiral sequence? As in cracking the outside bolts open first and then moving in a spiral motion towards the centre bolts? If you just cracked the right ones first and then the left, the head may have warped and seized the left side bolts in.

http://www.fordmods.com/forums/head-gas ... 26-40.html

The link above shows you how the head should be removed in sequence to stop the head from warping too much. You have to scroll down a bit.

Try putting the right hand side bolts back in and undoing them in the sequence from the link.

I used a 1/2" drive T-Bar and a 1m long hollow pole and slipped it over the T-bar handle...worked a charm.

Good luck mate

Heat the bolts & surrounding area with a blow torch. then pour some penetrating oil or solvent on bolts. you can also do do a search of a product call "Cold Shock". what it does is, it cools any type of seize bolts fast, causing it to crack & loosen it{fused or rust}

OR

leave a can of WD-40 in the freezer while you're heating up the bolts and surrounding. :P
don't forget to whack the f**k out of the bolt head. :lol:

i grinded a slot in the middle of the bolts when mine wouldn't loosen,then i used a chisel and a big hammer,took half an hour to get three bolts out.

didn't mark or scar the head at all.

OH MY GOD. They're off. I did it by tightening the right hand side line of bolts and then (this might sound strange) put an extensioner on the socket of of the left hand side. My reasoning is that the shorter the socket. The harder is seemed to stay on the bolt as I twisted. Putting an extension on let me keep it more straight and stay on the bolt.

There was a stubborn one the i used a dremel (A small angle grinder like thing) on and just slowly gridded it down.

Thanks everyone for the help. Was doing my head in.

Well at least you got them off :D well done. You might want to get the head checked now though, I suspect it may be warped :?. Now you know to keep the socket straight ;)

It's at the shop now. Pressure tested and machined and cleaned and all that. Now I just have to put it all back together. Hope that's easier

It is easy. Just make sure both the block and head are very clean. Rid of any oily substance by using some sort solvent. I used Kerosene to rid of any unwanted dirt and also removing oily stuff, such as some left over degreaser.

Make sure when you put the head back on that it is in sequence rather then just randomly tightening the bolts.
