Hi,

New member just joined and already looking for some assistance.....

Have a Triumph Stag (my wifes in fact) with original 3.0 V8 and it looks like the head gaskets are shot.

Stripped it down and got the nearside head off happily in a couple of hours on Friday but spent all Saturday unable to remove the offside head. Managed to get 3 studs out completely and one has snapped off 5mm inside head.

The last one though simply won't budge. We've had a variety of tools on it including dedicated stud removers on long bars, tried to free the head with jacking it up on the exhaust manifold and lifting the engine on the lifting hook at the same time to try and help shift it and smacking it around with a lumpy ona wooden block.

Used a lifetimes supply of various penetrating/freeing fluids and even had the tools attached to a rope and cranked on that with full deadlifting power and it won't budge.

Chances are it is going to snap (as per the other one) if I give it any more pressure and I will then have 2 studs sitting in the head. Hoping i can free this last one then get the head to move to free the already broken one.

This head hasn't been off in years and jusdging by the state of the stds that have come out, which are utterly manky, it is completely bonded into the head.

Does anyone have any crazy ideas that might help? Need to be pretty careful with it obvoisuly as alloy heads with cast block and lack of available replacement heads in case of damage would be problematic.

Does anyone know of anyone who could help with this while we wtil have an inch of one stud available?

Does anyone know anyne Midlands based (although will travel pretty much wherever at the moment) who could drill it out or go the molten metal route if need be?

All suggestions apart from throwing it in the bin gratefully received.

Heat the crap out of it. Heat the block around the stud and then try and remove using the tool.

Drill it out with a succession of larger and larger drill bits, then run a tap through to clean up the thread.

weld a nut to the top of the stud. whilst its red hot try and remove it. If drilling it out be very careful to only drill down the stud.
