What confuses me is there is no oil in the PCV to IM tube.

Checked the valve visually. It's by A&W, some aftermarket crap. https://ibb.co/0DsMwPq https://ibb.co/xFptJfh Put my finger in the exit to intake manifold a pictured, not a trace of oil there??

Spoke to Skoda, just over £100 for a PCV valve. Need to test mine though as I don't have any codes as I already said...

I have researched it on Google and this forum, and have been categorically told it won't fit, and requires a catch can instead. Maybe the CCZA cannot handle not having the delete kit and throws a code or something. Regarding the PCV, is it a genuine VAG one? And if so how much was it? I don't believe the 2.0TFSI will be a CCZA, as CCZA is 2.0 TSI not T F SI.

I've had a look and there isn't a blank off kit for the CCZA. You have a different engine to mine.

Got a link to the part from forge? What did you do with the new PCV and is it genuine?

Also, not getting any codes to suggest the PCV is failing, or any codes at all until the injector failed...

Nah, not the photos. Mine all looked significantly wetter/slicker than yours. Using about 1L in 1000 miles, but think its been getting worse recently, tricky to say. Anything it could be besides the PCV, and how to test it? The hose coming off the PCV to the inlet manifold wasn't particularly oily, but the intake pipe from the turbo to the TB was very oily. I hope this isn't a sign of turbo failure!!

I think I knee jerked a little with it being wet. Ultimately its burning an in spec amount of oil. I've watched some vids, and oil in the intake is very normal on these. As long as you aren't burning loads of it and you aren't smoking, should be ok. That inlet is not number 4 (the stuck open one). They all looked similar, big canon build up. They are all much cleaner now and ready for the injectors to be replaced. I dropped the oil too, and it's not significantly contaminated. Flushed a litre of fresh through to get any left in the sump. Injectors arrive Tuesday, so hopefully can rebuild one night. Got new oil and filter too obviously. Now with all new injectors, coils and a new plug on #4 we should be good for another 60k.

Pretty coked up and a little wet with oil There was a significant amount of oil in the inlet pipe to the throttle body. Going to clean the valves up today, but a little concerned about the oil.

Great write up. Will be using this to replace four injectors this week.

Cool I'll be prepared with all that. Can't find an IM gasket on ECP or GSF, guess its a VAG dealer only part.

Nice one. I did a compression test this AM and getting 165PSI on cylinders 1-3. Cylinder 4 was 180 but its still spewing fuel in. As its significantly higher and its only petrol in the bore, I'm not expecting it to be down on comp. I've ordered the injectors and will arrive next week. So will strip the manifold off this weekend and wait for the injectors, then do an oil/filter change and fire it up. Did you find it necessary to leave the car jacked up? I don't want to leave any kit outside for a week if I can avoid it. I want the bonnet shut and the car on the floor while I'm waiting for the injectors. Will block the ports with shop towels.

Got all of that stuff already so good to go. I found a guide written up on a few forums by the same guy for cleaning ports. He took detailed photos and put arrows on them to the bolts etc, but his photobucket account is giving a permission denied error. Don't suppose you found a paper manual or anything? It's annoying not being able to buy a Haynes for this model, I prefer paper rather than unlocking phones and viewing videos etc. I have the VAG VirtualBox image workshop manual, but its too complex to use out in the garage.

Is there also a spline type socket required?

Also is the inlet manifold gasket reusable? Any other parts/special tools needed?

How many miles since you fitted them? 260 including discount at Opie oils for all 4. Thanks all for your help so far.

I'm struggling to believe that those Bosch ones are remanufactured as it doesn't state it. I'm also struggling to believe there's anything wrong with Bosch ones, their reputation for fuel injection is strong. Ultimately if a few fellow forum members can assure me they have several k miles on Bosch injectors I'm good to go. Cleaning sounds ok, but for an extra 60 per cylinder I get new injectors.

106k miles, 09 plate. I've just spoken to a local VAG specialist who said he wouldn't use Bosch injector from ECP as they are remanufactured and not reliable. He said VAG ones are 175ea plus VAT He also said this is uncommon and he's not had one stuck open before. Not sure whether to believe any of that... I'm still tempted to just fit 4 injectors from Bosch and be done with it.

I can get the injectors for 290 for all 4. Not going down the £200 route as they'll get stopped in customs and slapped with a brexit fee. I'm debating whether just to replace the one injector, and get seal kits for the ones that come out. Or do them all.

Will speak to my trusty mechanic tomorrow, but hopefully he just recommends one injector and new oil. Would be easier to do 4 if the injectors come off though. I know the PO had a new inlet manifold fitted not long ago, reckon they would have cleaned the valves then anyway.

Odd that you had 3 go at once! Having valves cleaned sounds like was just done because easy while the inlet is off? Can't see how it would have affected your coil packs either, though I have already just changed all mine, and the plugs. I'm half tempted to change all the injectors while I'm in there. I can get 4 injectors for £307 from the site you mentioned. Tempting.

You brought it private, no comebacks there. It's not impossible that there were no issues before it was sold.

Chaps I dropped a cylinder on the M4 yesterday, and managed to limp home. There was no smoke out the back until I got off the motorway and sat in traffic for a few mins. Diagnostics said Cylinder 4 missfire, so I pulled the plug. It was soaking wet in there so I left it overnight to evaporate. Put a compression tester in there tonight, and got 180PSI as the first reading. Took 2 more, and it jumped up 20PSI with each attempt to read it. Pulled the compression tester and the cylinder was flooding with petrol, you could hear it pouring in. The injector appears to be stuck wide open. The battery is now flat (separate issue, but caused from all the cranking yesterday/today) so I can't continue with my compression tests, but the first test of Cylinder 3 was 150PSI, but didn't get enough rotations to be sure, and hopefully it is more like 160PSI. Anyway, once the fuel has evaporated again and I've done a compression test and I'm happy that all 4 cylinders are OK valve wise etc (will disconnect the fuel pump fuse for the next run)....I want to see about repairing this mess. An injector is £110, which isn't too bad. Taking the inlet off doesn't look too tricky. Apparently pulling the fuel rail could result in injectors coming out of the head and needing resealing - is this a big risk/big job? I'd need a resealing tool on hand if it happened, but would rather not buy one if I don't need it. Could anything else be at play here? I.e. a reason for the injector to fail? Could it be a victim of something else? Interstingly on the 2 longest journeys I have done on this car, I have seen an ECU code about it running too rich. I do wonder if this has been occasionally sticking open at times and it's only just become terminal. I will drop the oil, as there is so much petrol in the cylinder I would expect some of it to have watered the oil down by now. Is there a resource/forum with helpful people lying around waiting to help with this engine? Also, what engine bay fuse is the fuel pump? Cheers C
