[MDairheads] Exhaust Port Thread Question

[Kevin Fahey]

Evening All,


When attempting to remove the exhaust crossover pipe to clean trust from it and the exhaust pipes, I found it was rusted solid to both exhaust pipes.


So I decided to go ahead and remove both exhaust pipes.  They're pretty rusty.  I also wanted to make sure they hadn't rusted into the exhaust ports.


The left side exhaust nut came off smooth as butter.  Right side loosened a couple turns and then would not budge.  Having paid attention to advice passed along in the prior tech sessions I've attended, I went ahead and cut the exhaust nut off rather than force it off.


Found the reason it hung up was some slight damage to a thread as you can see in the attached photo.  I'm guessing it happened during a removal by a previous owner.


Looks to me like I should be able to clean it up with a die since the damage isn't too severe or too extensive.  Is this the recommended course of action?  If so, anybody know what size die to use and possibly a source that sells them?


Kevin
