Air breather question?

O.k. Two questions....

1st... I just started up my fresh engine and I did not have a Air breather on my valve cover. Since I just started in, and broke it in and drove around a little bit i wasn't too worried about it. BUT?? Should I have been? How long can you go with that breather missing?


2nd... Since I obviously need one, a friend was telling me to use the stock hose that runs up to the air cleaner because my car will run better. Yet, it seems 90% of pictures that I see everyone just uses a small breather.

Does it matter??

Thanks much!!
