Oil leak

You probably are going to have bigger problems than an oil leak now. You ran it out of oil and the engine is making a noise. That is a very bad sign. Have it town to a reputable shop for inspection and diagnosis to find out what you are dealing with.

A couple of easy to look for possibilities

1) Oil filter loose/ or the previous old filter's rubber gasket was left on the engine (now there is two with the new filter) I have seen them a time or two not leak right off the bat, but the old rubber would squish out later and cause massive leaking

2) Maybe your oil pressure sending unit is leaking (where the plastic part is mashed into the outer metal housing. I am giving you a link as to what it looks like.

The only way you will see this is to find the two items I have mentioned, is to fill your oil to the proper level, fire up your vehicle and look for the leaking.

If it is not at either place, you are going have to use a flashlight and look for the leak, wherever it is.

As far as your noise, I have no clue from listening to it from here.

You need someone local to access that.

If it is making the noise when you fire it up, cut it off to prevent further damage.

Again, the local guy needs to look/ listen at it.

Running an engine with no oil is not a good thing at all! (bad destructive things happening in an un-lubricated engine will make awful noises!)

Hopefully you you have done no damage.

Keep us posted as to your findings!
