Hello OK if the engine has fully locked up then either the cam belt has jumped a tooth ( or broken ) or the engine has ingested something If this is definitely a BKD variant then it already has the more robust oil pump drive and no balance shafts so that problem area on the previous generation versions has been addressed I'd start by popping the cam belt cover off and if that all looks OK ( timing marks line up) then I'd rent or borrow a bore scope to have a peer inside the engine through the glow plug holes
