I was wondering if you figured anything out on this matter. Yesterday I was driving and my idler pulley bolt snapped in 2. Not a big deal except when it did, it took a piece of the block off too. The o that the pulley bolt is supposed to go through now looks more like a C... Anyways, not sure what to do now. From the looks of things, I might have to invest in an entire new motor just because of this little piece. Please let me know.
