Well it depends on a number of things. How much time/money are you willing to throw into it before its not worth fixing up for yourself? It could be as bad as needing a new engine if the rod bearings went. However for $500CA you really cant complain. I bet you could part it out for a lot more than that. Also a determining factor would be how mechanically inclined are you? If you think you could handle an engine swap and are willing to attempt it and fund it you should definitely jump on it. Search around for problems that would casue these sypmtoms in the trouble shooting forum and you should get a good deal of help. Good luck, I say go for it and part it out if you give up on fixing it.
