here's my video not sure if you guys are going to catch what it seems like two metal clunking at each other a little bit after engine start..

oh yeah the clunking only last for a second and doesn't continue thats why i started the car 3 times hoping you guys could isolate the sound I'm talking about.

 

It's either broken motor mounts or your stater is getting stuck and grinding.

 

My friends S was making a sounds like that. and it was the starter getting stuck then slapping back. i would say test that first but they are a pain to take out.
