No.  Plugging the hoses just takes leaks out of the equation.
 
If your settings go to hell in a hand-basket when you reconnect the breathers, 
_THEN_ you know you have a leak.  The primary sources of small (non-
catastrophic) leaks are the seals - camshaft, and crankshaft front and rear.

(Or, in a car I saw recently, a Golf oil filler cap.)
