So I notice the gasket blown out between my hph and bowl
And I have a broken bolt
I've tried heating, beating, extractors and I think I'm e f'd.
Now what????
Any ideas how to get it out?

I have a way but only if the bolt is broken about flush to the bowl and you have a welder.
First step
Welding a washer to the broken bolt
Put a washer up to the hole and start your puddle in the center bringing it out to the washer.
Second step
Weld a bolt to the now welded washer.
Third step
Remove the bolt that has been welded to the washer.
If that doesn't work you can always remove the bowl and have a machine shop get it out. $$$$

use a drill , drill a small hole in what is left of the bolt. then tap in a extracktor that should get it out.as your trying to remover it use a little heat.

Carbide bit on a dremel worked for me on a broken head bolt.

Do not use an extractor....or you will have a broken extractor in your broken bolt. Extractors work if the bolt broke under tension, not if the threads are seized.
I'd set that thing up on the mill with a rotary table so I could use a few of the good holes to reference the true center of the bad hole, then go at it with carbide until enough is removed to pick the threads out. Depending on their condition, a time-sert may be required. If you're near long beach, I can do it for ya.

Thanks guys I thought I could get lucky and not pull the bowl
But no go
I'm going to pull the bowl and take to a buddy's to set up on the mill :banghead:

If you have access to an ocy acetaline(sp) torch. Use a small tip and heat just the broken bolt. When the part is warm (i would say just at red) quench the whole thing. The two dissimilar metals will expand and cool at different rates, and should break the bolt free. Or you could melt wax into it. They both are a stretch but, both ways do work. Very old school but effective. I have had to use both methods many times on some of the older cars we restore at my shop.
