I recall reading that depending on what revision of PCV you have on your car, when you replace it you also have to replace or do something else - another check valve somewhere else?! Sorry, thats a bit vague but I'm sure I read something of the sort here before.
Anyway, I'm looking for a bit more clarification on this if anyone can assist?
-
With the newer pcv's you also have to have a rear check valve that included in the rear pcv hose.
Early versions didn't come with the rear pcv check valve.
-
This is what the rear hose looks like.

Ah ha...
I replaced my PCV about a year or so ago and given I have an early 05 GTI its more than likely I don't have this doofer. Where abouts is this pipe, does anyone have a P/N and what would the symptoms be of not having the extra check valve?
Must say the car seems to be going fine with no particular issues...
-
This link show you where the rear breather hose with check valve is located. With your original set up the breather hose didn't have the check valve.

Does this still need doing if you fit a catch can. Will it help? Or only needed for the revised pcv stuff?
Thanks
-
The new part numbers are 06F 129 101 P for the PCV and 06F 103 215 B for the rear check valve.
The rear check valve is not needed when fitting a catch can but is needed if fitting the latest revision PCV if your car is older than an 07 plate. I removed my catch can and refitted my PCV valve. My reasons are contained within the link below. I find that my engine runs smoother now with the PCV fitted than it did when I had the BSH fitted.

What happens if you don't fit the new hose? I've not had it for over a year and I can't say I've experienced any issues. I will change it but curious about what the benefit is?
-
As above as I changed mine but didn't change fit (or know about) the pipe with a check valve
-
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:

That's good as I have done 3,500 miles on my revision N having changed it last September!
-
I'll check the invoice when I get home to see what revision it is
-
The part number for early VINS is 06F129101N and the rear breather hose is 06D103213G, which does not have a check valve in.

If you have a small mirror then you can check the pcv itself for the part number/revision. :smiley:

Would a duff PCV throw up an error code on VCDS or not?

Probably no...

It can bring up a P0299 fault code.

I fitted the 'N' revision PCV yesterday and the whole unit appears to be more robust, heavier than my old PCV and a much better fitment. I also fiited the NGK BKR8E-IX plugs and dont have any flat spots around 5000 to 5500 rpm like I had before. I was going to fit the RS4 valve to eliminate the flat spot but I dont need too now. I am not sure whether thats down to the better PCV or the new plugs but either way the engine runs loads better now.
-
I think I'm going to fit the latest PCV revision rather than my forge catch tank. When was the last revision made? And where can I find the part number on my PCV to identify which it is?
Thanks
-
Does any one know the part number for the extra pipe I need for the revision p to work on my 2005 gti?
Thanks. Craig

:stupid: Thanks, going to sell my revision p pcv and buy a revision n :smiley:
thanks craig

If the dealer sold you the part incorrectly. Id take it back and get it changed for the N revision.
-
I rang my local dealer up and the revision p was the part no they give me but told me they couldnt get it til today so rang another dealer gave them the part no i got from my local delaer as they got it in saturday just gone, so its the dealers mistake but i went with a different dealer and gave them the part no to get so dont think i can do anything about it?
Thanks craig
-
Always worth a phone call :happy2:
-
I'm on an early 07 place. March i think.
Can i install the N without the rear pipe then?
-
Ring your dealer mate, give them your reg or VIN and ask them what the part number ends in (they'll probably refuse to give you the whole part number). I was told the 'P Revision@ is for the BPY engine code, not BWA or BYD. The part number they gave me for my 2008 08 Edition 30 (BWA) was 06F129101N so I didn't require the rear pipe.
-
Every time i have spoken to my dealer or vw hq, they have been nothing but a pain in the crac and done me over. Whatever they told me i would have no faith in. unfortunately.

Thats pretty much exactly what im doing, changed plugs already and plan on doing the pcv valve when it arrives in the post, glad to hear you got good results by doing it - the plugs made a change straight away aswell :happy2:
-
i have a rough idle. I am thinking PCV for mine, is it worth going down this route or just buying the BSH version?

Having fitted the revamp and catch can, I can honestly say my car runs much better with the latest PCV valve.
-
I have the stage 1 bcs fix, do you think it would be wise to change back to oem spec?
-
Changed mine to a revision N couple of weeks ago and engine defo idles better. :happy2:
-
What does the N Revision PCV cost? :popcornsoda:
-
What does the N Revision PCV cost? :popcornsoda:
Cost me £35 at a VW dealer. Part no. 06F 129 101 N for the version i got which does not require the new hose with the additional check valve
-
What does the N Revision PCV cost? :popcornsoda:
David at Sere Motors will do it for £33 delivered, he's used a lot on the seatcupra.net forum :happy2:
-
I just got the N version Pcv and will be fitting it tomorrow, paid around £32 from VW Harrogate.
-

The pcvs are loads better than the early revisions that were released. My N revision is still going strong on my stage 2+ car. I find the engine feels smoother with the pcv and idles perfectly. You could fit a pcv and make the money back by selling the revamp.
-
Guys, I'm on an early 07 place. March i think.
What REV do i need, the n? do i need the rear pipe?
-
^^^ Yes "N" revision and no you won't need the rear check valve :happy2:

Just like SteveS, I've got an 07 Ed30.
Am I still needing the N version Part that Thor suggested 06F 129 101 N, which does not require the new hose with the additional check valve?
I might make the trip to the dealers tmrw. Thing is I've got not problems at all with idling etc.
Is it advisable to change now to prevent any future problems?
Or is it a case of "if it ain't broke don't fix it"?
....I think I know the answer really :ashamed: :ashamed: :ashamed:
-
I changed mine for peace of mind given the small cost for the valve.
-
Thanks Octy :happy2:
Yeah, for £30ish it's gotta be done!
Case of prevention better than cure :wink:
(are you in Lincolnshire btw?)

I think I'm going to fit the latest PCV revision rather than my forge catch tank.
....If you already have a Forge catch tank system why would you do that?
The latest PCV revision obviously is a great improvement but is it better than have a good catch tank system?
-
When mapping there car recently didn't someone find a fault with the forge or bsh catch can set up? Can't find the article now
-

....Well, I've had first BSH and now Forge catch tanks (much prefer the Forge) and my car gets regularly dyno'd and logged on the road by Jim @ JKM and there have been no related faults. In fact, the catch tank is thought to have contributed beneficially to the very good state of my valve stems etc < Recently inspected at 100,000 miles.
-
How do you find your idle? And how often and how much fluid would you say you drain? I know the forge is alot larger can than the bsh ones.
I've just put a revision N on my car and find it to be alot better built than the one that came off, my idle is better, as for the condition of head internals I couldnt comment

....Depending where you stand/sit, idle is no noisier/quieter or smoother/rougher than before any catch tank was fitted. My car is a 06-build and had its original early revision PCV.
I only drain the fluid when it gets close to the level indicator line (Forge). How often depends mostly on weather temperatures and types of journeys.
More info in my review here: http://www.mk5golfgti.co.uk/forum/index.php/topic,16343.0.html
Certainly, if I hadn't already got a catch tank system I would consider upgrading my PCV to the latest revision but I can't say that I still wouldn't go for the Forge. I'd need to research the subject more to get a more direct comparison.

RR, can you explain why the catch can would be thought to contribute to very good state of valve stems at 100k inspection? the TFSI is direct injection is it not? Just trying to learn, not challenge your statement :happy2:
I would have thought that using high quality fuels with detergent additives such as those in V power and BP ultimate would have a far great impact on the condition of the valve stems. ??

Note that I wrote "valve stems etc" - I'm repeating what I understood from Jim @ JKM after he dived into my engine to investigate a loss of power when on February's Dyno-Day.
I'm confident that high quality fuels also contribute beneficially in one way or another. I hope this helps explain. :happy2:

I think it was because George hadn't fitted his Forge catch can kit yet, Robin. He sold it brand new and unused to me. I am going to fit the Forge however as my car is having an APR HPFP an new cam follower fitted soon, before going Shark Stage 3 and I believe a catch can is a must for more highly tuned cars. The fact that your engine was found to be in such good conditon at 100K miles recently has encouraged me to follow suit. My car only has 17K miles at the moment and I feel that the Forge catch can can only help keep it in good health, along with regular maintenance. Do you find your engine bay more smelly with the Forge fitted, Robin? :smiley: xx

....Hi Paullie :smiley:
A good move to fit a catch tank system as soon as 17k miles and coinciding with tuning.
Was the Forge one you bought a silver one? - I'll PM you about it soon (after I've watched 'Neighbours'!).
No, because the Forge system doesn't vent to air (illegal for road cars in the UK I think), there are no smells. However, you can smell the gunk when you empty the tank. It's not the sort of fragrance you would want to dab behind your ears before going on a date you wanted to impress! However, if you went on a date with a car enthusiast and dabbed Castrol R behind your ears, the world would be your oyster!! He (me included) would be putty in your fingers!
-
Well I'll be sure not to use the catch can gunk in place of my usual fragrance then, :grin:. It's not the silver one, I bought the brand new black, stealthy one that George had for sale last week. Can't wait to get it fitted! Thanks once again for your infinite wisdom :love: xx

@ Paullie:
Just had a call... Gotta dash n collect my car and visit Shabba at vanworx... Will Pm ya later re Forge can :happy2:
