Oh god here we go

On my way home from work, my engine developed a slight knock...I pulled in the driveway and tried to determine where the knock was coming from...I thought it was the adjuster pulley because the bearing was worn out and rattling a little bit...so i replaced it but when i cranked it up to see if i fixed it the knock was definitely a LOT worse...And now i think im on the verge of throwing a rod through the oil pan...
It sounds like the bottom end towards the 1st cylinder...
And this engine only has 15,000 miles on it!!!
It was brand new, Not rebuilt, from the factory...Wtf.

Im taking it to the shop in the morning since it is under warranty and im goin to let them look at it...

I threw a code about a week ago for a knock sensor...Could this have anything to do with it? Any help is appreciated.
If i get a chance before work tomorrow, ill upload a video.
