finally figured it out!
Removed pre heat hose and sheat metal from downpipe. Also there was a wire that went from an unconnected connection boltet to the valve cover down to what probably was a timing sensor or something on the block. Rattling sound is now gone. I think it was the wire that made the rattling sound it was very hard and brittle, and when i tapped it it made almost the same rattling sound. I'm happy that there isn't anything wrong with the engine, it would have been strange since the engine has been cared for and has only 105K.
