335i Free BOV DIY Help / Question

So I am sure you guys have seen this DIY on here. Now I just had a few questions and the thread seems to not have the answer so I thought it would be better to bring it here.

1) Is this safe for our cars?

2) As I was playing around with it today I was only able to get the front plug loose. The back one wouldn't budge. I tried it with both the cower on and off but still both didn't help. I stopped tugging on it because I was afraid of it breaking. So if it is okay for our cars is it fine to just have one unplugged and the other one plugged in ?

Thanks for your help.

I did it the other day. Now I have a boost leak. Don't know if it's related or not but I am never doing it again.

Yes it's safe. Just be sure you have the intake side capped off from where you unhooked the DVs. Just unhooking 1 shouldn't hurt anything.

Were you able to get your logs to terry to confirm that you have a boost leak?

kfrazie1 · 07-16-2012, 07:20 PM

I wouldn't do it.

Unfortunately no. I don't have a usb cable. I am 99% sure it's leaking, and I am picking some up wednesday from a forum member to see if that's the issue.

Yea its capped off so it doesn't suck in and debris from the engine bay.

Also how did you notice you have a leak?

I am still stock so I don't have a way to read boost etc

I'm thinking I have a weak DV. This mod theoretically shoudn't cause it, but I think it's a wierd coincidence. I still don't know if I am leaking for sure, but I think so based on the surging boost at part throttle (which you will feel as inconsistant power) and a vacuum sound while on the throttle. I only have JB4 and DCI.

both plugs pulled or just 1

Bavarian Made · 07-16-2012, 10:12 PM

Same boat as you here my friend, I can't out the rear one and don't want to mess with it, but the front one comes out easily. I just don't know if it should be done with just one. I have a DCI, so I get a little bit of the BOV sound, and when I unplugged the one in the front and revved it up a bit I didn't notice any sound increase.

saxon · 07-16-2012, 10:17 PM

as long as you plug the holes for the intake it works perfectly fine, its only going to get the you bov sound and no other benefits/drawbacks

max_k20 · 07-17-2012, 12:13 AM

Just buy a DCI. After adding Injen DCI to my car I could clearly hear spooling and a Bob like sound from stock DV. Now with the tune we can hear it a lot more. As I said just buy dci and you will enjoy it a lot more !

I have a DCI already.

I had it out for the drive to work but I was worried about it and I felt like the car wasn't running as smoothly as normal (I know it was probably just in my head)

That and I didn't notice much of a sound difference. (yesterday I test drove it with the cower off which is probably why I heard it a lot more)

So I plugged everything back to its original state.

I'd save up and just buy a charge pipe w/BOV

plenty pop up in the FS section for around $350. The ricer side in me wants one so bad, but the conventional side says it's not worth it haha
