Air leaking from small hose on engine (1 Viewer)

[griffinsurfer71]

After changing my heater tees, noticed this small hose on top of my engine was leaking air. I’ll attach a photo below, as a temporary remedy I put some duct tape to stop the air from leaking out.

If anyone could help me identify this hose it would be greatly appreciated

PCV hose is my best guess, if anyone could confirm that would be awesome. It’s a 2001 Cruiser

Yes powersteering idle up hose. Generic works too but oem is also not expensive and 100 tomes better. Replace both hoses going into the power steering pump and return. Be careful when pulling the hose off the nipple as excessjve force can break the nipple. Use a pick to break the bond between the hose and the nipple.
