Re: [Chevelle-list] Exhaust Manifold Bolt Removal

I agree with Mike, if you have a welder this is a great way to do it. Not only do you have a nice new bigger nut to grab, the heat from welding helps loosen the bold.   Trooper ----- Original Message ----- From: Mike Holleman To: The Chevelle Mailing List Sent: Tuesday, February 07, 2006 3:15 PM Subject: Re: [Chevelle-list] Exhaust Manifold Bolt Removal An old timer taught me that trick many years ago. It rarely fails.

The larger the better as long as you have clearance. I would use a 1/2" nut on the 3/8" exhaust bolts. Then carefully impact it out while it is still hot from the weld. Mike Holleman ----- Original Message ----- From: Rob Shaffer To: The Chevelle Mailing List Sent: Tuesday, February 07, 2006 1:15 PM Subject: [Chevelle-list] Exhaust Manifold Bolt Removal I have a question for the list that is not specifically Chevelle related, but is chevy related nonetheless.  I'm removing the exhaust manifolds from a 1995 Chevy 454 engine to install headers.  The passenger side manifold bolts came out with the help of an impact wrench.  On the driver side, I've got all but three bolts loose.  I stopped when one of the tough bolts started to round out.  Now I need to remove the bolt, but cannot get a grip with a socket.  I think Craftsman makes something that will grip even a rounded bolt head, so I'll give that a try, but thought I'd ask whether anyone has any advice on removing these last three bolts.  Any tips to remove the bolt that has started to round?  How about just removing the stubborn bolts?  Should I heat them first?  Any tips that have worked for you in the past will be appreiated.  Thanks.
