Use anti-seize compound.
Johnu: You probably know this, but get used to the idea of removing stuff to get proper purchase on most any bolt. You don't need a lot of special tools to work on this car . . . .but actually you do. I've bought several sets of "things" to get one particular wrench for one job. Socket head allens might help you here, but I expect you should remove the intake and then you'll find more stuff that needs attention and pretty soon, you'll have the exhaust off.

This car sucks if you have OCD... just starts with an innocent intake refresh, damn now the TT, engine, exhaust, and gas tank are out of the car...

This penetrating oil info has been floating around the web for years. It was first posted here by Wally Plumley, who, iirc, has tried it and says it works. Others on this forum have reported similar results. Here are some links from this forum.

Here's one of the links that shows up if you google "machinist's workshop penetrating oils."

Good luck with your fix. I'll give you ONE HUNDRED US DOLLARS, Cash on the Barrelhead for your car if it will stop you from pushing it over a cliff.
P.S. Manual Impact Drivers are fabulous tools.

Machinist's Workshop Magazine (March/April or May/June, 2007) actually tested penetrants for break out torque on rusted nuts. Significant results! They are below, as forwarded by an ex-student and professional machinist, Bud Baker.
They arranged a subjective test of all the popular penetrants with the control being the torque required to remove the nut from a "scientifically rusted" environment.
*Penetrating oil ..... Average load*
None ..................... 516 pounds
WD-40 .................. 238 pounds
PB Blaster ............. 214 pounds
Liquid Wrench ..... 127 pounds
Kano Kroil ............ 106 pounds
ATF-Acetone mix....53 pounds
The ATF-Acetone mix was a "home brew" mix of 50 - 50 automatic transmission fluid and acetone. Note the "home brew" was better than any commercial product in this one particular test. Our local machinist group mixed up a batch, and we all now use it with equally good results. Note also that "Liquid Wrench" is about as good as "Kroil" for about 20% of the price.
There are lots of shade tree engineers who ask, "How do you scientifically rust a batch of fasteners and parts?" I haven't found a link to the actual article but, if it were me, I'd simply clean a bunch of new nuts, bolts and iron bars and dump then in a barrel of salt water for a few days, then bolt all the pieces up and leave them in the same position and same place outdoors for a few months if I lived in Key west, or a few decades if I lived in the Tucson - or skip the barrel of salt water and go straight to the bolting and leaving. Maybe spray salt water on them every day. That'd pretty much make all things equal. After that, it's off to the vise with the torque wrenches and a notebook.They arranged a subjective test of all the popular penetrants with the control being the torque required to remove the nut from a "scientifically rusted" environment.

welcome to 928 ownership..
I did the wp/TB job 2 years ago. I was lucky that i had a GOOD exotic car shop do it and the entire intake before i bought it... everything came out dandy..
other projects... not so much.

Success!!!!!!!!!!!
And the winner is...........Phil928!!
I drilled as much of the bolt head as I could, then beat the crap out of it with a mallet and chisel until the head was all broken up. After that, I cut a slot in the top of the remaining bolt and it came out easily! Waterbridge then could be wiggled out.
Thanks again everyone....you saved the '87 from going off the cliff (or being sold for a hundred bucks!)

Use a hack saw to cut off the bolt. If the blade is the same thickness as the gasket you won't harm the sealing faces too much.
Take some video as it goes over...if you do that.

Hang in there it will all be good in the end.
I think we have all been in your shoes at some point.
