Engine knock can often be a failed bearing on the crank shaft, if this is the case the engine if run much further will do serious damage.

If this is a none turbo engine then you most likely have been driving it with no oil. I agree with mhpautos that you will be damaging the crank shaft. Very common on none turbo engines to consume oil.
