Just before I rush over to TPS to buy one, can anyone tell me if I'm right in thinking my PCV has failed?  Loud squealing, as if a belt is knackered, and RPM all over the place.  Pull the oil dipstick out, rush of air, noise stops, engine splutters and almost dies. Put the disptick back in and puit your finger on the little hole on the right side of the PCV 'disc' and the noise gets even worse.  

 

Knackered PCV?

Yup, prognosis is correct!

Sounds like PCV.

Yeah it is, check the split in the photo in post #2

Oh yeah. pretty knackered. Annoyingly, the oil separator assembly is not that cheap for the EA888 2.0 TSi.

TPS have quoted £67+VAT, so ~£80. 

 

The current part number is 06H103495E but I'm not convinced that that's the latest.  I don't suppose you know what the latest part number is?

I thought it was 06H-103-495-AH. I think that would supersede E?  TPS should be getting latest parts though, so maybe you will be supplied AH? I don't have erwin,  someone else may read and confirm latest revision.

Thanks.  ETKA gives 06H103495E which matches what's stamped on my PCV.  However, ETKA also says it's cancelled since 2013, but gives no updated part number. Perhaps it means it's cancelled as that's when the MKII production was ceased?

Mmm.  But they don't normally cancel all part numbers on the model run ending do they?  Skoda parts lists version AD:

 

http://www.skodaparts.com/product/octavia-oil-separator-2009-2013-51069

 

AH presumably surpersedes that and I doubt that parts website is always kept up to date for revisions as it is just a parts department listing for a skoda dealer, so they may supply AH.  You'd think there would have been at least a revision since the E installed on your car wouldn't you.

 

Maybe call a Skoda dealer part department or another TPS and see what they come up with.

Yeah that makes sense, blond moment on my part  I'll try VW now and if not, I'll just get TPS to order one in.

On my April 2011 car, just had a look and it is revision H fitted presumably from new.

 

So there has to be something later than E. The TPS person must have got confused with what was fitted to your car at manufacture, versus current replacement part? I doubt they can supply E if it is cancelled.

I think he mention AJ, which is presumably newer still. I'm just waiting to hear from my trusty indy to see if he can get one sooner, otherwise I'll just get TPS to order one in.

Well, for 2.0 TSI engine code CCZA is last modification separator 06H103495AJ. It surprises me you have now 06H103495E as this is old one for 1.8 TSI from same family.

 

But to be fair, when I look at other brand, Audi A3, they make no difference between 1.8 and 2.0 TSI EA888 concerning oil separator and last one they say is 06H103495AH... Mess as always in last few years... So it seems AD and AJ knows only Skoda and maybe VW, do not know what to think about it. I am sure it is related to oil issue and pistons+rings trouble as breakpoint is June 2010, time when modified pistons+rings were introduced ... will post here details for Passat CC just to compare.

Well, below summary of all oil separators for CCZA engine mounted in VW Passat CC with timing and all version used.

This confirms the post from v0n where he nicely summarized actions taken  from VAG, optimized separator was first stage

I guess this is the source info to the first stage, original russian version and machine translated in English.

So yes, I guess at begining all, 1.8 and 2.0 TSI family EA888 engines, used same oil separators, but when oil issues came on stage, from June 2010 VAG introduced many new separators and splited them according engine capacity and fact 2.0 have AVS and few other specialities...

Thanks for all of that.  Mine does currently have 'higher' oil consumption: I've gone from max to min in ~1600 miles, so nothing too serious.  

 

So that PDF suggests I need AH?  It seems to flow as such:  

 

06H103495E > 06H103495AC > 06H103495AH

 

But then at the end of the document, it says 'TILL 14.6.2010' (which includes my Oct 2009 registered 2.0 TSI) it says 06H103495AJ which is the part number mentioned by TPS also.

Well, Skoda says for CCZA only new separators, VW still have at ETKA those two groups separate. In light of these information I would stick with AH. But it´s only my personal view based on data from VAG catalogue. Before you buy, try to pop in few dealers and ask what they will offer to you, do not mention you have info too, wait what they tell you. Then you can confront info you have with official dealers knowledge. Based your engine is made before June 2010 as registered already 2009 , I really do not know what to advice more, have experience only with 1.8, not 2.0. Know only from photos on web new ones (H+AD+AJ) differ a bit from old ones (E+AC+AH), haven´t seen it on own eyes.

 

Sorry fot that mistake on last page with printscreens from ETKA, it´s my fault, should be "from" instead "till". File corrected.

 

Well, 1l per 1600 miles not the limit but almost, VAG has really high limit of 0,5l per 621miles, I believe safe is only up to 0,2 per 621 miles.

What mileage you have and what oil do you use?

Car's on ~78'000 and I use Quantum longlife III 5w30.  We believe the car is leaking from the lower chain cover but I'm also wondering if it's leaking from the PCV seal also.  

When it should only leak through lower chain cover, than would be the better case Have you new timing done so the cover was off?

 

But you are right with PCV, in case crancase has too much oil vapours, PCV can´t cope with it and too much oil goes into manifold and turbo. How does look the connection above the turbo, dry or oiled? Few details here https://www.briskoda.net/forums/topic/426138-ea888-20tsi-oil-leak-or-pcv-problem/?do=findComment&comment=4835827

 

When the PCV mebrane is cracked now, I guess top of the engine looks bit oiled around it, am I right?

From what my trusted Indy has said, when the timing cover was removed to replaced the tensioner and chain etc, they just bodged it by reusing the same parts. They didn't replace gaskets etc. and instead using a sealant.  The top of my DV and pipes leading towards the turbo have oil all over them, which initially made me think that the DV was needing a replacement. I've since learned that that part is fine.  I have oil around the top back of the head (behind the coil packs) which now makes me think that the PCV has been leaking very slightly also.  

Well, lower metal cover use liquid sealant, when carefuly removed (no twisting, bending, etc) can be reused, but always important to use right sealant. Upper one, made from plastic, has rubber seal, must not be used any sealant.

 

Yes, your symptoms show the PCV must be bad longer time, At first, get new PCV and clean the engine including intake pipe leading to turbo. Check the pipe especially around inlet port for the PCV. Try to use another oil and fixed service interval, VW502.00 with ACEA A3/B4 might help yet, such as Castrol EDGE Professional A3 5W-40 or similar.

When it gets oily again, I am afraid nothing else helps than new pistons+rings

Ah OK, perhaps I've misunderstood.  How easy is it to get to the pipes? And by clean, do you just mean to disconnect and flush them? The inlet pipe (which I believe is the one at the rear coming from the turbo) had quite a bit of oil in it.  I had to drain the PCV of oil when I removed it. I'm not talking loads and loads, but enough for it to drip out.  

 

I thought Quantum longlife III was a favoured oil? I know it's really designed for variable servicing, but I was under the impression that it would be fine to use longer life oil even when on fixed as it's just slightly better oil?

Well, concerning oils, many and many opinion, but I do not trust in LL service regime on personal cars, even petrol ones with higher temps. LL pecfect for trucks or personal diesels running often long journes.

 

Concerning cleaning the pipe, not very complicated, user TheClient has it done and has few photos to that here but if you are not sure, let it do your indy. Pipe or its rubber link to turbo was modified, so important is there is no crack on it. I guess only outside wash should be good enough. From what I know, every separator PCV get slight oil film on these engines, but never should get in condition oil drips out of it.

Interesting. I was under the impression the Quantum LL III was the same as what VAG use in the factory but rebranded?  I remember that thread but I'm not entirely sure which pipe it is?

My garage have just replied with 06H103495AJ, so I'm very confused.. 

 

I'm struggling to find anywhere that stocks the AH so I'm thinking that AJ is the only way to go.

 

And I take it I can't simply purchase a new diaphragm on its own?

Edited 17 May, 20179 yr by planehazza

The volkswagen extracts seem more complete. My vehicle is April 2011, revision H is fitted.

 

Your car is presumably earlier than that (i.e pre 13.06.2010) and has E fitted.

 

VW suggests E => AC => AH (most current)

 

And a different path for 14.06.2010 and later vehicles If I am following correctly...

 

H=> AD =>AJ (most current).

 

So, I guess if I was replacing in my car, I would go for AJ. For your car, based on earlier build and E fitted, AH.

 

Can there really be that much difference though? And how come the skoda Etka histroy doesn't appear to reconcile to what was fitted to cars, the VW one looks far more representative unless we both have replacement items fitted.
