i have a 2000 audi a4 1.8t, rod knock? cam chain tensioner ? lifters ? belts? something hitting the heat shield? oil problem?

recently Ive been hearing a strange noise coming from the engine.
-the noise goes with the rpms.
-the noise goes away when im on the highway driving
any other info u need , just ask

Heres the video

You need to re-do the video without the helicopter hovering in the background, then maybe we can tell what's going on with the engine.

Maybe it's just my computer, tho.

 

lol thats the engine man. there was no helicopters around

 

Turned out to be a broken flexplate. its gonna cost 800-900 to repair
