Alright, maybe it's because I haven't had my morning coffee or that I'm just not real educated on the PCV system on this car but I'm a little unclear. I know you said it should be a simple DIY but, you also said it's an Internal pcv valve. Will this require removing the vavle cover or no?

Valve cover will not need to come off, this will be about a 20 minute job.

I may be way off by saying this but I recall VWs that modify the PVC with a block off plate to completely "delete" system. Could this be an option for the n54 so we wouldn't have rediculous carbon buildup on our valves?

I'd prefer to run some PCV system personally but that is up to you good luck if you try it.

Then you miss the whole point of relieving crank-case pressure.

I assume when they did that they also did a vent to atmosphere OCC?

My question is why cant you close the PCV that runs to the intake manifold off and keep the one that connects to the OCC and then connects to the intake open so everything is drawn through the OCC. The intake should keep enough suction to keep the pressure out of the crank case.

Just picked up a 2012 335is, saw the threads on cleaning intake valves/ports, looks like Rob is on the right track. Subscribed!

Dzenno but closing the part that runs to the manifold and making the secondary part that runs to the OCC open at all times wouldnt this still do what the PCV is meant to do and vent the pressure out of the crank case. Just instead of it going to the manifold it would go to the OCC due to the intake systems suction.

You could do this and then weld a venturi bung onto the ********* and route the PCV down to the there so you are always scavenging. Might clog the cats eventually though.

Hey Rob, I have the exact problem TWNEGO has...ocasionally puffing smoke on decel when coming to a stop, sometimes not at all.

I know "everyone" is quick to blame turbo seals, however I think there is more to it than that.

I am hoping it is more of a PCV issue has my turbos boost very well.

Anyway I can get in on the testing? In fact, I'd pay you for the parts to test as well.

(the smoke is a bit embarrassing at times )

I don't believe is the turbo seals either. Mine started puffing white smoke on decels after I installed the ******* ***. It smokes only occasionally, but when it smokes, it puffs big clouds of white smoke, for example when decelerating to stop at a red light . I agree with you that it is embarrassing. My car quit smoking for a while after I changed the spark plugs a couple of weeks ago, then last week I was bored and changed to map 8 (non-turbo map) and when I changed back to map 3 (the map I normally use) the car started smoking again for a day or two. I don't see the relation of the white smoke with changing maps, however I just wanna to share my experience. I hope this upgraded PCV, that Rob is developing help to solve this

Ive got them ready and packaged, still haven't been able to mail them out though. Hopefully tomorrow, that way about half of you should have them by the weekend.

Default UK tester - 04-16-2012, 04:34 PM

Hello Rob,
topical for me.

I pulled my MAP sensor last w/e and noticed a LOT of oil in the manifold and the sensor was gunked.
My first thought was PCV - and here I am after a bit of searching

Can you sell me this mod, I can PayPal and I'll take a chance on it working or not.
Of course I will clean everything and report back - Im a keen spanner monkey.

I dont get through much oil, but whats coming from the breather indicates I have a recent fault here.

Thanks
Steve UK

Cant wait to hear how the testing goes on these. Right after a cold start coming to a stop sign ill get a puff of smoke out my exhaust and it smells like oil. I have a BMS OCC and my car only has 28k miles on it. I wouldn't doubt that it might be what you're talking about in this thread. I really hope its something as simple as this.

PM replied. Yes I will begin selling them if anyone is interested. I have about 10-12 complimentary units going out for testers so I should be good there but if anyone wants to jump ahead and make the purchase without all data and feedback possibly available that is fine by me as well. I really think there will be no disappointments either way, this obviously is a much more sound unit.
