I was taking my exhaust loose from the manifold or where the two pipes connect the exhaust to change oil pan gasket. Upon loosening the nuts, the nuts got tighter the further I turn. One of the nuts stripped and I left the other two alone, but they have been broken loose.

Question is, how do I get these 3 nuts off. After they broke loose they seemed to tighten back up. Thanks.

 

You may have to drill the broken one out. Did you use any sort of penetrating lubricant when you tried to remove it?

 

get a grinder or dremel and cut that bastard off then put new studs in it and use anti-seeze on them !

 

Just turn the others until they break off. Then hammer out the broken studs and replace them or use nuts and bolts.
