How To: Evaporative Re-Route and Boost Leak Fix

[jewfro]

I did both this mod and the WG pre-load adjustment a few days apart on my 2013 and the impact is as significant as so many others have stated.

It's truly one of those "should've come from the factory this way" mods (if you can call it that).

Well after a couple weeks the dreaded P1CEA code came up for me. I'm not going to address this for a little bit (this little light of mine, I'm gonna let it shine) as I will be changing intakes shortly (Horay for Black friday)! I was sloppy with my check valve / line placement out to the intake knowing full well it would get re-done when I go to FMIC + fenderwell intake. However, I was digging around the internet and came across this from EC:

Now this method makes a lot of sense to me, but I really haven't found it discussed anywhere. And EC now actually sells a different boost leak kit (not this method). Is that because:
1) It costs more and is more complex?
2) Its not a good method?
3) other?

I would say likely 1.

I went through the process of developing an in-line diaphragm valve system that self actuated at 6psi, but in the end I just found it to not be worth the complication, and future leak point. A simple plug on the intake pipe and hose from evap to pre-turbo intake is a much more elegant solution, that doesn’t “leak” under low boost. On my car the intake draws enough vacuum to effectively purge under boost, but I did trip P1CEA once in almost a year of plugging the leak.
