urdrwho Posted July 17, 2013 Share Posted July 17, 2013 On my 97 Subaru Outback I was cleaning the engine port, that the BPT bottom hose attaches, the metal tube that goes into the engine. I noticed that there is no vacuum nor is there any air coming out of the tube, there is nothing. There is nothing when I rev the engine. On my 95 Legacy that tube has air coming out of it. Should my 97 have any air coming out of the metal tube, be it vacuum or blowing air? It is my opinion that there should be something at that port.

Zues Marine Posted July 19, 2013 Share Posted July 19, 2013 look at the vacuum diagram sticker under the hood... it'll show you how things are supposed to be hooked up Link to comment Share on other sites More sharing options...
spooln30 Posted July 19, 2013 Share Posted July 19, 2013 Are you talking about the steel tube running from the cylinder head to the egr valve? Link to comment Share on other sites More sharing options...
