Hey Guys
I broke one exhaust manifold bolt while removing it. Then I commenced to make a mess of the bolt hole while drilling it out. It looks like I'm not going to be able to replace the bolt for the exhaust manifold. Can I run my 850 minus one exhaust manifold bolt. It's in the middle on the bottom. Will it effect anything. I'm gonna try to fill the hole with permetex steel weld then retap it. My friends telling me it won't hold even though it claims to be machinable. In the event it doesn't hold anyone have any suggestions. I really did it this time. I just replace two valves and lapped all the valves replaced the valves seats. I don't want to go out and get another head from the boneyard after all the work I put into this one. Can I run it minus one exhaust manifold bolt?

 

You can run it, but you'll probably get a slight exhaust leak form it, if your state have no emission, no big deal.
