Why Did My BMW Engine Fail?

In this video I open up my N54 engine and find out what it failed. I show you what failed and disassemble it and show you how it looks.
This engine came out of my 2008 BMW E90 335i.
In the next video I get the new engine and we will do some basic maintenance on it before putting it back in the car.
If you missed the last video my motor experienced rod knock after doing a 3rd gear pull.
Please leave a comment if you have any theories as to why it failed.
