The hose going from the throttle body to the passenger side valve cover broke. What does this hose do and is it really important. Right now i have it clamped off and taped up.

 

Get a new hose. That hose, along with the PCV, provides ventilation for the crankcase. You'd be better off taking the hose off all together than to clamp it off...

 

A length of 1/2" hose and 2 90 degree plastic elbows will replace it fine..

 

I just took the hose into the parts store. They didn't have the right stuff, so I bought heater hose that was the right size. It was a tight fit on the elbow that comes out of the valve cover. I bought like two feet, and then cut it down to fit. No need for elbows or anything. It cost like $5 or something for the hose.
