I just started having problems with my turbo civic.First off a I was driving and I pushed in the clutch to downshift and it died.I got it home and the front of the block theres a screw that was leaking antifreeze.It was hot and wouldnt start.Finally I got it started and I hear a loud knocking noise when I rev it.I was just wondering what might be wrong with it?Its a B18 with a B16 head.

 

You threw a rod.

 

yup you blew it up...def sounds like a rod knock
