Knocking Noise from 81 300d
 

took a video of what it sounds like

<object width="425" height="355"><param name="movie" value="http://www.youtube.com/v/wLXf3mUlxyc&hl=en"></param><param name="wmode" value="transparent"></param><embed src="http://www.youtube.com/v/wLXf3mUlxyc&hl=en" type="application/x-shockwave-flash" wmode="transparent" width="425" height="355"></embed></object>

Tried using a mechanics stethoscope to identify where it was exactly coming from and no luck.
Any ideas as to what or where it is coming from?

Links did not work..? Hopefully just your injectors and not a rod. Did you get under the car w/ the steth.?

try it again

but yeah i got under the car with the steth and still couldnt not find out the exact location of where exactly it was coming from

this may sound dumb, but check to see if your alternator bracket is loose
