I also fully agree with Alan and Bob's comments, but if you have a snapped off BOLT then you will have to remove this first as the head will not slide up the studs without the bolts removed, they lock against one another. The only way I have ever removed a snapped bolt was by drilling out but only down to the block face. I have never had any success with the rope trick. I ended up making 2 plates that bolted to the inlet faces of the head and then used a 3 ton bottle jack to push the head up so that I could cut the studs off.

Best of luck with what can be a pig of a job.

In the early 90's I had a head stuck with the ends of some of the studs broken off from welding nuts on and turning them, incidentally this technique worked very well on the other head. I read in the club magazine of a firm somewhere that had a factory head extractor tool.

I remember driving a few hours from dorset, and the tool doing the trick in a matter of minutes, but I can't remember where it was exactly. The South East somewhere I think.

The tool was a large steel plate that in turn had shaped plates which bolted onto the exhaust manifold face and inlet manifold face. Large diameter bolts with inverted cone shaped ends screwed down onto the studs at the appropriate angleand jacked the head off far enough to cut the studs. I thnk it might have been a Saab tool but I'm not sure.

Does anyone else know of that tool and what became of it? If it still exists it would be handy if a club member were to come by it, or at least be able to borrow it for a while to make a copy.

Good luck getting the head off Tim, it's a pig of a job when they're really stuck.

The original post certainly was but my post was to give a pointer to anyone who had head removal problems and seeking a solution read the post archive. They would then be able to view a photo of the device until e-Bay archived it.

Can you post a screenshot of the eBay where you saw it. Is it a tool which is not already covered in the Head Removal document in the Technical Section of this forum (which shows several different methods to remove the heads and studs)

I bid for that tool on eBay and it was an exact copy of the one in the tech section. Unfortunately I didn’t get it, think it went for £220 in the end.

Once the head is up about 12- 15 mm , cut the studs. Any less can be risky.

use this to remove the short cut off studs.

Amazing results for such a cheap tool.
