ADDW1 v3.3 Catch Can - check valve question

[Denis]

hi guys,
My kia dealer just installed hks45iL plugs, Lap3 chip, and ADDW1 v3.3 Catch Can and Im picking up my car this morning.
The catch can only came with one check valve but it should have 2 check valves. The dealer installed everything anyways and said to just order another check valve which i will do today.
My question is, is it safe to drive my car with just one check valve installed on the catch can?...

I also sent an email to Jack at ADD W1 and explained the situation but her only responded that he will send me another check valve without answering my most important question.... is the car safe to drive?

You should be fine for now, just use the one check valve you have on the PCV can (one closest to firewall if they followed the installation/one with shorter tubing) as this one collects more oil than the CCV side, which I have read multiple times from other members. I just have a single can setup for this reason.
For added reassurance just put some tape over the missing check valves hole so no oil at all will escape the catch can.

I got paranoid after reading that someone had the ADD W1 check valves fail and suck pieces into their turbo. I upgrades to UPR check valves. They handle higher vacuum.

Thank you so much... I can rest a little easier knowing this. I will still get that other check valve installed as soon as it comes in.
Thank you!W

How do I get my hands on the UPR check valves that you upgraded to?

Good question I was also wondering. To bad OP went crickets on it.

They installed my Lap3, intake, catch can, and they will be doing the Eibach sway bars (front and rear) with springs next week.... I can't wait!
I do pay a bit more than I should to get these parts installed but in return, I can sleep easy at night knowing that if I have any issues, they will take care of everything...

Can you take some pictures of your catch can install and post? Also did you get the other check valves. I checked the specs on the ones that come with it and its rated to 100psi . Same as the UPR.

I'm going to install my own.
