What was going to be just replacing the oxygen sensor has turned into so much more. After using heat, wd40, and a breaker bar to remove the old one, I was left with the old oxygen sensor's threads still in the crossover pipe. Great. So I thought, hey, I'll remove some stuff to get more clearance and go from there. I removed my driver-side engine mount and the part that the stud goes through just disintegrated right in my hands. I'm not sure how that is put together exactly. The actual mount bracket isn't damaged, but the part that the stud goes through broke in half, and then continued to crumble the more that I touched it. Was this aluminum at some point? Right now it looks like a big piece of crumb pie. I also found some more frame rust underneath the engine mount, so chances are I won't be driving my car for awhile unless I develop a death wish. What can I do about the engine mount issue? Do I need a new block??? a very sad Matt #1604 To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
