I have an 85 NA z31, and recently replaced the rocker cover gaskets. In the process of removing the intake collector, a couple of those stiff rubber hoses on the right side of the motor broke/split. I'm still trying to figure out what the other one is for, but one of them is a hose that is connected to the air regulator. Is it possible to run the car without that hose? I was trying to get the car ready for a trip that would be around 300 miles. Would it be dangerous to drive with no hose for such a long distance, if it will drive at all? Also, where would I purchase that particular hose? Thanks.
