bnmejia79, engine knocking and blowing white smoke usually is a good sign of internal engine damage, have a good technician have a look, diagnose and estimate repair. May be best and more cost effective to have engine replaced with a good engine from an auto recycler/wrecking yard if tech. gives you bad news$$. Good luck. I hope this helped you out, if so let me know by pressing the helpful button.
