The knock sounds like it's in the right top end, it doesn't knock at an idle, but high idle is when it starts. I just finished doing head gaskets in it, and didn't hear it run before I did them. The guy I bought it from (and the guy whose house it was stored at, that was a subaru mechanic) said that it ran really well, it just leaked about a quart of oil per week. The guy I bought it from is my dad's friend so I trust him on that. If anyone has any idea of what it could be, that would be awesome. Check out the link for the video to hear it.
Thanks in advance,
