I was wondering if a small hole in the egr tube would cause 3 codes to occure and a loss of power?

P0401 yes, the other 2 are intake leaks usually. Since there is an egr flow code I would replace it first then wait for it to throw codes again. You might have a clog in the tube or excess build up. Fords are notorious for blow back stock or modified they cycle the oil breather through the atmospheric port on your intake which in turn cycles what I call oil vapor through the intake.
 






Year make and model of your vehicle --along with specific engine it has would help. please fill in your profile and we will not have to guess
