Broken Exhaust Manifold Bolt - solutions sought (1 Viewer)

[PJ40]

So before I plug my old new 2F into my 40 I'm wondering if anyone has any cool tricks to get a broken manifold bolt out. I hadnt' noticed it when I purchased and will be tackling this when I get back from vacation. Thanks in advance

Need more information, where is the broken bolt; can you get at it with a drill bit /extractor / lefthand drill?

A picture of what you're working with would really help narrow down what is needed to fix it.

Engine is currently palletized and I have unfettered access to the bolt. I've looked at different extraction techniques online but wanted to reach out to the 2F experts

Take a can of penetrating oil with you and get a head start on the soak

A good start would be a left hand drill bit. Some stuck bolts will just come out easily after the head snaps off. Be sure to soak first, as mentioned. If you have clear access, I would just drill it with the proper/exact bit and use an EZ-out. But, take your time and study it as you go, so you don't snap off the EZ-out.

If there is a stub left, mig weld a nut on it. The heat shock and something to get a wrench on will get it.

Now, does anyone know what size and thread pitch the bolt would be (furthest one back, by the firewall) Block stamp indicates engine is a 78
