I was looking under the hod today and i noticed the pcv hose from my valve cover was off my 1999 9-3. I took a look and saw that it was broken. While i tried to reattach the hose to the throttle body, I broke the check valve in two. Now i have to buy a new one which are pretty cheap (around 20) and some hose to connnec it back to the throttle body. My question is will i ruin anything or have major performance issues since the hose is no longer connected to the nipple type thing on the throttle body and continue driving for the next few days until eeuroparts can get me the parts. Right now it is curretly connected to the throttle body but lacking the valve.
