I'm doing a timing belt change on my 90 legacy 2.2 which is the first one I have ever done, about 130k on it. So I've gotten it apart (having read all the amazing advice on these boards) and realized that the pulley has worn a groove all the way through the outer timing cover which doesn't appear to be warped. When we broke the bolt loose it was definitely tight, so tight as it broke the first socket. This makes me wonder how it could move on the crankshaft at all. There are slight signs of rust and I'm thinking I should replace the pulley when I put it back together with either a new one or a seemingly good one from a wrecking yard. The crankshaft doesn't look damaged or scarred. Any thoughts on this would be appreciated.
