## Questions & Answers

**Q: What does this part actually do? the one in my 2008 gmc acadia appears to be duct tape fixed and i’m wondering how important it is**
A: It's very important

**Q: is oil supposed to go through this tube? my 2007 acadia has oil in this tube**
A: Yes it’s part of the pcv system google it. Just relieves pressure from the crank case. Blow it out with an air hose or clean it with soap and water if not damaged and just blow thru it. I cleaned this hose and the intake breather and throttle body every 20k or so and never had any gasket issues with our Acadia

**Q: is oil supposed to go through this tube? my 2007 acadia has oil in this tube**

**Q: Is this just the tube or are the end pieces attached as shown?**
