Engine leaking oil

[Fullern90]

Hi yesterday while driving my F-150 my engine got slightly louder and last night after a whole day of driving, my engine blew all 5 quarts of oil out of the right manifold pipe, what might be the problem?

Year, engine and mileage?

Trashed your ring(s) or burned a hole in cylinder(s) 1,2,3 and/or 4.

Not looking good for the engine.
