Leak vs Leakage?

Question

English is not my first language and I'm having trouble using the words "leak" and "leakage". Do they both mean the same thing? or what is the correct grammatical usage of each word?

Thank you very nice people :)

The word "leak" can be a noun or a verb, but "leakage" is only a noun, so that's one difference.

When used as nouns the two words can have the same meaning, i.e. "an act or instance of leaking" or "any means of unintended entrance or escape."

The word "leak," however, can also have another meaning which is not relevant to the word "leakage" and that meaning is "an unintended hole, crack, or the like, through which liquid, gas, light, etc., enters or escapes."

The word "leakage" also has another meaning which is not relevant to "leak" and that is "something that leaks in or out."

As someone wrote on this forum thread, put very simply: "a leak is a hole, the leakage is the water that runs through it."

The definitions of the terms used in this procedure are:

A leak is the quantity of fluid that comes out of a component that is sufficient to become a drop or drops, or will possibly become a drop (approximately 20 drops = 1 cc, 75600 drops = 1 gallon)
A leakage is a quantity of fluid on the surface of a component that is not sufficient to become a drop
A stain is an area on the surface of a component that has a different color. It is usually caused when fluid leakage dries on the component surface after high temperature operation.
