I think I have a bad PCV leak...

Post by Nibbib »

So before I posted about running extremely lean under full boost well today I installed my aem tru boost gauge which I love lol. But when I was running the vacuum line to the gauge I noticed that the PVC line that goes to the driver side head was really loose so I wiggled it and I don't even think it's hooked up

Would this cause my car too run lean under load and I'm pretty sure idle high

Does anyone have pictures of the intake off and the PVC system hooked up?

I'm sure if someone with an engine on a stand would be willing to snap a few pictures for you. Based off the diagram what hose are you referring to that is broken?

It would be either ten or nine in the Pcv sticky in the intake section but with out taking off my intake im sure the other side isn't hooked up since the driver side is so loose

Sorry bud I was on my phone and didn't catch the Turbo part. So my diagram wasn't too helpful. Edited and posted the correct graphic for quick reference.

It's all good haha just really wondering if it isn't hooked up if it would cause my car to run lean under full load and run rich under deceleration?

Someone correct me if I'm wrong but I don't think that leaking has anything to do with your lean/rich issue. I'm thinking fuel delivery isn't enough psi under full load possibly. That happened with my stock fuel pump until I upgraded to walboro

I already did the walbro pump I've posted before about my issue and people have said to clean my iacv and that should fix it but I'm thinking it's just gone bad... Possibly
