I just noticed that the rubber vac line from the intake mani to the VC on my car is busted at the end where it connects to the valve cover, and it causing a leak. its the one that runs right behind the spark plug wires and has the 90 degree bend in it. my question is, can i use just any piece of black rubber with a 90 degree barb fitting to replace the whole thing or is it some type of oneway valve where ill need to get it at the dealer? sorry for such a probably dumb question. thanks for any help.

Your PCV valve is inline on that hose. You can replace the section that is split, but you still need to keep the elbow because your PCV valve is in there.

look at my sig...you can see a red hose..I had the same problem. Went to NAPA spent like .50 on a peice of hose. No Leak anymore.

Yup, any hose will do. You definitely need to replace that vacuum hose because it will cause your car to idle high and/or rough.
