engine knocking

[jonesmp7]

Just picked up a 1990 240sx. It has the ka24e motor in it and when I got home it starts knocking!!! Not sure if it's cam, or rockers. I am gonna have to do engine mods first now because of this but not sure what. Any suggestions?

post a video if you can, could be a rod knock or timing chain
