2.4journey2013 Posted October 2, 2020 Report Share Posted October 2, 2020 Finishing up getting everything back together. Have a question about where the hoses on the front of the intake manifold (2.4) are supposed to run to? One of mine is just loosely hanging with an open end, to me I would assume with the MAP that would cause a vacuum leak? Quote Link to comment Share on other sites More sharing options...
John/Horace Posted October 3, 2020 Report Share Posted October 3, 2020 Pic would be useful. Start car and listen for the vacuum leak, plug hose back in. Egr often has vac hose. Clear the codes that might be generated by running with vac leak for a minute. Quote Link to comment Share on other sites More sharing options...

2.4journey2013 Posted October 3, 2020 Author Report Share Posted October 3, 2020 I'll get it a picture later today. It's the 2 hoses right by where the throttle body bolts on. Quote Link to comment Share on other sites More sharing options...
2.4journey2013 Posted October 3, 2020 Author Report Share Posted October 3, 2020 It's one of these hoses. I think it's the one closest to where the TB mounts but information on where both go would be cool. Quote Link to comment Share on other sites More sharing options...
John/Horace Posted October 4, 2020 Report Share Posted October 4, 2020 I don’t have a 2.4. I would guess Purge vent valve is close by, it’s for emissions. Will creat code if not hooked up. Size of a D cell battery. https://www.rockauto.com/en/catalog/dodge,2012,journey,2.4l+l4,1502335,exhaust+&+emission,vapor+canister+purge+valve+/+solenoid,4936 Quote Link to comment Share on other sites More sharing options...

2.4journey2013 Posted October 5, 2020 Author Report Share Posted October 5, 2020 Update: Just FYI, one of the longer hoses goes to the brake booster! Quote Link to comment Share on other sites More sharing options...
