Massive oil leaks.

I just got my brand new 512 running today. Only a short 20 mile ride from the installer to my house and got home to find everything covered in engine oil from front to trans. Total FUBAR. All brand new parts covered in oil. Brand new headers wasted. The builder gave me one breather on drivers side and said that's all I need. I just called Mazzolini and he says the 50-70lbs of pressure probably didn't cause this but only having one breather may have done. Anyone thoughts?
