CN90, On your post #164, is there a step by step somewhere you can point me to? For example, I'm looking for details on the hose you're using to cap off the old ccv, what size is it and what mechanism did you use to secure it to the hoses going to the ccv?

- geobrick...I did this a long time ago, so I don't remember.

- When the weather gets warmer, I can check each and individual hoses and make a detailed list of items so people can get these things ahead of time for the job.

Thanks.

- I have a 2004 X3 2.5i with very very minor RMS leak. Maybe one drop on the garage floor per night.

- In my previous posts, my theory as to how this CCV Mod works is that there is extra vacuum in the crankcase. In that case a bit of air is drawn in via the RMS.

- If this is the case, then the CCV Mod should reduce or eliminate the RMS leak?

- Has anyone here has a RMS leak and after doing the CCV Mod, the RMS leak goes away? Just curious...

Hello.i would to try this DIY but the PCV valve you added I can’t find on eBay or somewhere.
I can’t buy from autozone because I’m not leave in US
So someon else who could suggest me any other Eshop in Europe or any other PCV valve who will work in this DIY?
