i was changing my oil today and when i took out the bhaf and intake pipe i saw some oil on the fender well. it is apparently coming out of a hose with a funny cap on it. it sits about 4" in front of the pcm under the bhaf. the hose runs from the fender well to something on the front axle, passenger side. i am not familiar with this at all. there is not alot of fluid on the fender well and it is cover with dust so whatever is coming out of it is doing it slowly. seemed to be spread out to much for gear oil, but then again i dont know what i am dealing with. Can someone please enlighten me.i also heard what i think was the belt tensioner pulley starting to squeal. after it warmed up, whatever is was quit. pretty sure it was the pulley though. The FSM says it is serviced as a unit but i can buy just the pulley or the unit. any of you just replaced the pulley?
