Just thought I'd share my findings with everyone.
I own an Edition30 with DSG box, I love the car to bits, hand on heart I'd say best car I've owned by miles, and I have owned a few.
The story goes, my other half and I were coming back home from been in Manchester, and as you do, sometimes, you give the car a bit of stick running down the slip road onto the motorway, all seemed fine and the sun was shining. We drove north for a good 16miles or so, taking it steady until we reached Accrington, we turned towards Accrington town centre which is a 30 zone and so we bimbulled along at or just below 30.
Now this is where, a blokes heart stops, and head spins, we came to a series of traffic lights and were in a queue with a few other cars, we set off and I thought I saw blue smoke from the rear of the car :stupid: thought to myself dont be soft, and made a passing comment to the other half about it, as we set of from the next set of lights, sure enough we both saw a cloud of blue smoke, and it did indeed come from my car. Well you can only imagine the horrors going through my head, and of cause the other half asks, I take it that's not good, to which I reply, your not bloody joking it's not good. ( bent valves, blown turbo, turbo on way out )
So we continue and arrive home, I just got out and left the car running and walk around the back of the car, no smoke, nothing, I asked the other half to jump into the drivers seat and give it a good few rev's still nothing :stupid: :stupid: :stupid: we switch car off and go inside and chat about did we really see it then, the blue smoke that is ?? So over the next few days we keep an eye out for it, I even got the other half to drive my car, while I followed in hers, and still nothing.
So onto the internet I went, and did alsorts of research from both sides of the pond, and the only thing I could work out was the PCV, as basically this collects gasses and oil valpour and throws them into the manifold to be burnt off, so my thoughts were if the PVC was nackered, maybe it was pushing/allowing oil into the manifold, and this is where the blue smoke came from. So for the sake of £80 for parts, I went to VW to order the parts, and they questioned way I was doing it, and said they had never heard of it failing, they suggested I bring it in and they do checks on the car ( Which would of cost me more ) I politely refused and continued to order all the parts required.
The parts arrived at VW, I collected them and armed with all the new parts, PCV and rear pipe, and laptop for install guide, away I went stripping old parts off and installing new parts.
Now bear in mind, my car had none of the symptoms a failed PCV, would show, it all seemed fine.
I took the PCV off and it was caked in oil in the inside, it was like someone had dip it in a bucket of oil, even the gasket was covered inside and out, clearly oil had been running freely through it. Nexted came the rear pipe off the back of the engine, and blow me down that had lots of fresh oil running down it, clearly something wasn't right, and this is where I new I had done the right thing.
So I changed over all the parts, my PCV on the car was 3 reversions older than the current part and the rear pipe on the car was 2 reversions old.
1500 miles later and I have seen an increase in MPG from 26/28mpg, to around 33mpg/36mpg, my fuel tank used to run empty from full at around 280 miles, now the best I've seen is 385, but now mostly around 340/360 miles to a tank, and so far no measureable oil consumption.
I would highly recommend this upgrade/update of the PCV and rear pipe, it may just slow, stop how much oil your consuming and the bonus of better miles to a tank :drinking:

Have you got the part numbers please?

Interesting. I might be doing this as I've got a 2007 also. BTW how many miles are on your car?
Also can I get the part numbers for the PCV & pipe that you changed? Thanks
-
Have you got the part numbers please?
I went in asking for these:-
PCV valve cover assembly: 06F 129 101 L
PCV valve cover gasket: 06F 103 483 E
PCV valve cover to turbo hose: 06F 103 215 B
PCV tube to turbo metal gasket: 06F 145 757 F

You've fitted another older Rev L instead of N?
-
Did you happen to notice if the PCV check valve was broken?
Also the latest PCV that works is a revision N which has superceded the L. There is a rev P, but you need to change out the rear hose also with this one.

They give me the latest on the data base, I just used the list as to what I needed, not for the part numbers. The folks at VW said a couple of the part numbers were out of date, and ordered me the latest ones showing on the system.
I just used the list to show the 4 parts I wanted

Thanks for this info, which one of these are you calling the rear pipe?

By the way I have a BSH blank off plate which doesn't use the pcv system so is it a good idea to revert back and use the latest revision pcv maybe it might help things lol

I wouldn't...

Why do you say this? Is the blank off plate better than the latest OEM PCV?

Would like to know this too ^^^

If you look at the VW race series cars they use the oe pcv. The old ones used to fail but the new ones are much stronger. I know since i fitted the N revision pcv my car drives much smoother.
-
This may have already been mentioned, but you only need to change the rear pipe if your pipe is the valved tipe. I upgraded my PCV to the latest version, but didn't need to change the rear pipe as it was a straight pipe with no valve :happy2:

Am tempted to try out the PCV and see how it goes

Which pipe is this?? Any schematic pic/photo?
-
Kiwi,
Please put up a link to the "install" that you used. As above, any more info/pics on the rear pipe.
Cheers bud.

George,
Where is this pipe and where am I looking to see which one I have on my 08 Eddy.
Thanks, Martin

Are you sure, as everything I have read, suggests you need the rear pipe with check valve, or the install is pointless ???

Hi George & Martin,
Here are a few of the web sites I took info from, these are just a few, but they do explain it very well, and have pictures of the changes and pipe

It is suggested in all the guides I have read, that the rear pipe with the check value is required, or it makes upgrading the front PCV pointless. Take a read on both links posted above and make up your own minds :happy2:

Hi Guys,
As with most peeps, the title of this thread has piqued my interest! :smiley:
Like most on here, im most meticulous and anal to the mainenance and upkeep of the car :grin:
Im all for upgrading components and carrying out preventative maintenance - especially where components are prone to failure.
Im not that clued up on all things mechanical but can follow a simple how to.
Can any explain in layman terms what the PCV does and why the upgraded / updated part perform better?
Is the PCV that was installed from factory on my 57 ED30 prone to failure?
Also, is this worth doing or is it a case of if it isnt broke, dont fix it?
sorry for all the questions guys...
Cheers :happy2:
Rich

Cars that have the rear check valve installed will need the P revision. Cars that have a straight rear pipe need the N revision. If yours needs the P then you will need to upgrade the rear pipe too. If not then you dont need to bother. Both PCV function the same so neither is better than the other.
-
Apparently the revised ones are supposed to help reduce oil consumption on these oil hungry engines. My car came with the F version car built March 2008 which is the dual valve version. Mine is on it's original with 124k on it and it's been tuned all it's life and seems to be ok but might change it to see if it reduces oil consumption.
-
So am I correct in thinking that basically we would be fitting 2 check valves instead of the 1 which we should be running?
I run the L revision with no rear check valve.
-
Thats what i used to run was the L but i updated to the latest one for ours which is the N. The L didnt really need changing but I did it as the N is stronger than the L and I am running more power now. I see no point in fitting a rear check valve on cars that dont need them.
-
Is there any downside to fitting the rear pipe with check valve ?
Would have thought that the latest version would stop any blow by of oil on full boost. I know i "shouldnt" require one with my revison N pcv but have ordered one anyway from TPS £23.53 assuming that i already have one on my 07 Edition 30 anyway.

PCV tube to turbo metal gasket: 06F 145 757 F
So you've fitted a rev L and not N :confused:
I've just ordered a Rev N 06f129101N
mine is also a 2007 Ed30 ..

When on full boost the rear check valve will be open as thats how it vents. When off boost it vents from the front pcv.
-
Just fitted my Revision N just now and removed the old Revision L. New Rev N now has 2 check valves in the housing rather than the one large valve located in the main body. A small check valve is added between main housing and rocker box housing.
So far car seems alot more eager and idles alot more happier.
Will keep an eye on any improvement to MPG.
-
Right I'm considering changing my PCV now, I also have a 57 plate edition 30.
Should I just get the Rev N housing or do I need to change the pipes/hoses aswell?
-
Thanks for posting this info up. I am currently searching for info on the PCV system on my mk6 to see if it works similar to the mk5 as i think mine may have gone faulty. http://www.mk5golfgti.co.uk/forum/index.php/topic,51922.0.html so this info and links you posted is very useful.

Just the Rev N and rubber sealing gasket I changed on mine aswell.

Have you done any before and after logs Steve to see if there was any differences?

No mate, haven't logged it, but my bum dyno says it feels better :ashamed: :grin:
I will say that, there's now feeling on gear change from N to D on initial move off, and certainly seems a lot smoother up the gear changes as well.. Kind of like it's getting cleaner air and less oiler stuff from the recirculating system.. Might be placebo
-
Was just curious.
-
I noted the idle was more steady and the boost seemed to come in smoother. Now I fitted the G rev DV, the car is purring like a big puddy tat :happy2:
-
I replaced all of mine today asell as a new DV, somehow the rear pipe had been crushed and the gasket was missing between the turbo housing, so hopefully might get a bit of extra benefit by fitting a new gasket and and uncrushed pipe :wink:
The front PCV i removed was already the latest revision, so that was a waste of money :stupid:

Must remember to check the part number on mine before I order a new one.

Some of you will have had your N revision on for a while now, have you noticed any reduction in oil consumption?

Similar Thread here: http://www.mk5golfgti.co.uk/forum/index.php/topic,43801.0.html
If you want the latest PCV that will work on the earlier engines without the rear check valve you need the 'N' revision. They are the same as the P only they work without the need for the rear breather hose as I believe they have stronger spring inside. I am getting the N revision so I havent got to bother fitting the rear breather hose :jumpmove:
Are we saying if the N for the front system is fitted we should or shouldn't replace the rear breather should the valve inside the rear breather pipe be found faulty?
Thanks
-
With the N, no rear check valve is needed so the breather pipe does not need replacing.
