A Rolls Royce Silver Shadow found me.

Yeh, it'd have had me to drink by now, too. I guess you're heading past that rapidly.

Can you rig something up, maybe using the threads of adjacent studs, to try to pull the head up that stud?

Pretty sure I've seen such a tool made for Jag V12s so it sounds a plan.

[Huntsman]

It seems the replacement engine I bought is scrap. Humph.

The right hand head remains stuck on one stud. I have soaked it, heated it, cooled it, beaten it and its been hanging from the shed roof for 2 days with the whole weight of the engine and engine stand hanging from the head and it won't budge. Crunt.

I welded a nut on to see if some twisting action would free it off, it was solid, I started very gently and increased the effort, the weld broke and I wrecked the thread and nut.

I could attempt to drill it out, but its in ali and its 4 inches or so long, chances of not wandering off into the head material are slim and its a long way to drill.

Buggeration.

So the end of the stud is buggered, but that's it? Scrap might be a bit OTT.

Have you tried using adjacent studs to pull the head up?

Can you get any kind of a gap between the head and block? I have heard of people cutting through studs when similar problems have been found on the Stag V8

I have thought of that, but I have about 1mm of gap which is full of old gasket and I can't see it working without damaging the face of block or head or both.

Tonight I'm going to bang it back down, lift it up, repeat until fed up.

I could make a long skinny hole saw and go down the outside of the stud making the bore in the ali casting bigger. Needs a very specific size piece of tube (this solution might have some legs).

I could try and drill down it, but its pretty tough material and 4" long, the chances of running off sideways are high.

I might buy a whole car.

Can you describe in detail how to do that?

That doesn't sound like a winner then.

How about using some plasticine or blue tack to build a dam around the offending stud to allow it to sit in a pool to penetrating oil for a few days? Maybe with the weight of the block hanging off it for good measure.

As it happens there is an ali turret around the stud in question, its been full of thinners, petrol, WD40 etc for days, I even tried brick acid.

[Rangeroverover]

At least you've got a mooring anchor out of this

Huntsman said:

Nuts would down as far as you can onto the adjacent studs, then some kind of bracket above them, hooking onto maybe a manifold port or bolted to a rocker mount or something handy. Then wind those nuts back up, which'll pull the bracket - and thence the head - away from the engine.

Googling Jaguar V12 head removal tool - there is quite a bit written about them. This is where I have seen them used (Hooli too possibly, since he was a member of XJ40.com)

No use to you since it's the wrong engine - but this listing for a V12 removal tool has photos showing how it works:

And a removal tube being used

Thanks, interesting. I see how it works. Sadly on the Rolls head there are no cam bolts to retain the plate, even if there was, if I was going to engineer all that it would take considerable time and money, I might as well buy another engine.

I've not ruled out buying a complete car...

Pull up on a port?

Yes, I see it might be possible, but to make up chunks of metal man enough to do it is going to be more work and expense than buying another one.

Anyone got a cheap rotten Shad 1 to sell me?

Are you a member of the RREC. They have a good forum on there that can give advice. If you are not i think the Australian version of the RREC is a free forum ( dont haver to be a member to ask) and it seems they are more into DIY on the Shadow and Spirit variants than over here

Exhaust valve looked a bit pitted. £80 each. Ooof.

Oof indeed, that's spendy enough to make an old fashioned valve grinding machine look attractive; they pop up on Ebay occasionally and don't fetch much.

Busting the weld before shearing the stud means the weld wasn't up to much; how grunty is your welder?

The other way of getting a stuck head off a Stag V8 (many tricks are required) is to feed some nylon rope into the cylinder through the spark plug hole and then crank the engine. If you put enough rope in you should be able to get the head to pop up enough to get a saw to the stud.
