The car is a 95 Legacy LS sedan, 2.2L 4eat with no modifications. The issue is the crank pulley is backing out. The timing belt was done about 3 months ago (not by me) so I am unsure whether it was ever torqued to spec or not. As you can see by the pics, part of the crank bolt is chewed beyond the threads. I also think it is slightly warped at this point. Additionally, you can also see by the other pic the crank pulley itself is somewhat chewed up from it spinning loosely for some time. I threaded the bolt back into the crank and it went in with no issue, seemed just a little "loose", but not excessively so. Key on crank is solid and complete. So... A. Replace pulley B. Replace bolt (loctite?) C. Put a magnetic tip in to the crank threads and see if part of chewed bolt is in there D. What else? What could have caused this? E. Anyone have bolt and crank pulley for this laying around?
