2015 - PCV connector Hose B Routing (pictures)? - SOLVED!

RFulton · 2025-10-03T18:39:59-0400

My 2015 Forester 2.5L renewal project hit a snag; I hope you can help me. The PCV Connector Hose B. I know it routes from the connector over the top of the driver side of the engine. I can not recall what it connects to. Your help would be appreciated.

Hey, I'd be happy to help you figure out where that PCV Connector Hose B goes! From what I recall, it should connect to the intake manifold or possibly the valve cover. Do you see any labels or markings on the hose or nearby components that might give us a hint? Maybe we can troubleshoot together and get your Forester up and running again!

@Todd Edward No Barb on that side of the Intake. Valve cover has no barb. Nor the lower intake on that side.

Off the top of my head, it looks like the hose that attaches to the barb located on the intake tube into the throttle body.

I thought that might be, but the throttle body barb is 1/8ID" and this hose is 1/2ID". The Heater hose collent pipe has a pigtail pipe/hose to the driver's side of the TB.

So it sounds like the PCV connector hose might be a bit more tricky to track down. Can you check the other side of the intake system or maybe consult a repair manual specific to your Forester's model year? Sometimes those diagrams can help pinpoint where a part might be supposed to connect.

MYManual shows connect Hose B, but then refers to FIG.073 which I have not found.

That's what I was referring to, I think I described it poorly though lol.
