Hi all,
I have first gen alpha and trying to remove Y pipe. This style has only three bolts, the bottom one being long and having an allen head. Wouldn't you know it was frozen. I eventually ruined the allen socket, so I figured the thing to do would be cut off the head and try to work the pipe off of the bolt shaft. Cut the head off cleanly, but the bolt is frozen inside the aluminum casting. Other two bolts are out and the pipe is "free" - it moves, but it won't come forward due to the frozen bolt.
Any suggestions for how to free it up or otherwise get that bolt out of there? I have oxyacetylene, I could gently heat it while working the pipe. Is there a magic chemical you've found that will dissolve that encrustation that has welded the bolt into the casting?
Thanks.
