Answer 1
Don't waste any money on fuel. Best have a professional technician listen to your engine to determine how serious of problem you might have. -
Answer 2
have a diag done by a mech and don't drive until then you can cause more damage -
Answer 3
Most probability crank shaft damage due to lack of lubrication, May be a good time to decide to fix or replace Engine or vehicle . It will be a significant expense. Before you make that decision , have a shop check for loose bolts to the flywheel. Some times it sounds like a bad rod . -
