Default help me engine knocking dont know where??

okay so heres the deal...my buddy and i were driving my hatch and a wrx pulled up next to us...he was revving his engine and wanted to race so i downshifted to 3rd and smoked him...right after the race my car started over heating so i drove it back to my buddies house about a mile away from where we were...as i got into town i heard knocking coming from the engine....after we pulled in to the drive way i popped the hood and looked around...to my surprise i saw oil all over from my turbo...i looked closer and saw that the oil feed line was disconnected...then i checked the dipstick for oil and saw none...so i added about 2 1/2 quart of oil into the engine and tightened the oil feed line...i went back to start up the car hoping that the knocking was gone...but nope still there...so where the hell is the knocking coming from....my head?? rod bearings?? hopefully nothing expensive because i just bought the motor 2 weeks ago freshly built...

My gauge on my talon pegged 40psi one time on my holset. Came home heard it knocking and didnt think anything of it. Added oil but the sound was still there. Ripped it apart one day and found 2 bent "big" rods.



YOU'RE FUCKED!!!!!!!!!!!!!!!!!!!!!!!!
