Lightbulb hose

It is your right side pcv (positive crankcase ventilation) hose. There's also one on the other side. They carry the crankcase vapors to a fitting near the airbox where they are sucked into the intake manifold to be reburned. I just replaced both from subaruparts.com, and now it idles better, too!

hose

Probably won't hurt much, but you may get some oil spray on the engine around any hose hole, and the engine is inhaling unfiltered air thru the gaps in the hose. Also, any air that is pulled in thru the leaking hose is bypassing the MAF so it alters the mixture some...probably what changed my idle after hose replacement.
