Massive oil leaks.

A little oil can go a long way in making a mess. How much did you lose? I'am guessing a pint. Anyways it don't matter. Just fix it. You chose the breather setup right? If you want only one breather it should be big. Not one with a half inch tube thru the cover. This will give you a chance to check out everything real close. Make sure its all good, the way you want it. Its a learning experience!
