Can someone please tell a newb what this hose is? It's showing signs of wear and kind of hard to get a new one if you don't know what to call it. Thanks.

 

PCV(positive crankcase ventilation) systems Vent hose

Diagram here of PCV system: AGCO Automotive Repair Service - Baton Rouge, LA - Detailed Auto Topics - What are the Symptoms of a Bad PCV Valve

Vent hose allows FILTERED fresh air to be pulled into the valve cover as PCV Valve and hose suck engine air into the intake manifold

So Vent hose will always get air from air filter box or between the air filter and intake

 

Thanks, That works

 

Good

And just remembered it was/is also called a Breather hose
