Btw, I got reported qutie few cars had the front seal blow here in Korea, too.
The solution for it is adding another breather or opening all PCV lines and breathers to the air (seems stock pcv system is not working properly for FI engine.) , then...

the amount of the gas is different depends on the engine, but, usually you can see quite excessive blowbygas from all breathers like the link.
even with the blowbygas , the car is working well without any noise and abnormal sound from the engine and still fast (the dyno number is still the same as before)
What I am wondering is whether the engine is Ok or not with the situation.
Have anyone tried to checked the pistons and rings with the seal blown?
