Love the vid .. ive goy A6 c7 2012 2.0tdi .just replaced everything like you have and now the injector grommets on the rocker cover have started to seep , which now i no what my cure can be and to use sealant, i have just ordered the oem audi ones so im gonna give those a try 1st and if fails again ill put some sealant on ..
Heck yeah, awesome video. About as perfect of a DIY video as you can get. I checked out 3 other videos, and a lot of the comments state that they came here only for the injector seals in the valve cover, and it still leaked after changing. I think this video sums up why you should do the whole valve cover gasket. From when he turns it over after he takes it off, you can see how much of a groove that seal has to go around the underside valve cover. I bet my bottom buck all of these people that still had issues only tried to pry out the lip seal in the installed valve cover and couldn't see that the new seal was pinched and not seated properly on the underside when reinstalled. Quick question, I have OBD11, What function in the diagnostics do you use to bleed the system? Is it just the lift pump like you would use to do a fuel filter, or is it a different function for past the HPFP?
Thanks for comment. I don't know how it goes in obd11 but in VCDS program it is called "Transfer Fuel Pump (FP) test" check this video m.th-cam.com/video/mN-VpKsbwCA/w-d-xo.html And this one m.th-cam.com/video/g3FumjE5jcU/w-d-xo.html So yeah one more thing about new and old injector seals, original sealing are from KACO and they sits prety tight in place so you need to press them rly hard to get them out and this new ones are from Elring (no offense to Elring the are one of the best out there) you can install them with one finger easy so i think without sealant they will leak very soon. And if you install original seals from KACO you should have no problem at all, in my opinion.
Very good informative video, but I have one question , why did you put silicone sealant on new gasket and seals? I suppose the purpose of seals and gaskets is to seal perfectly fine without any sealant or I’m wrong?
Thank you for your question MilanI I thought about adding this explanation to the video but I guess I forgot. So usually it is not necessary to apply sealant but in this case I applied sealant to the injector seals in valve cover because they did not hold in place so tight as the original ones and applied sealant to the valve cover gasket because of the wider space between the bolts . So I think that the gasket will last longer with sealant wihtout any leaks and also there is a lot of dismounting in here so you don't want to do same job twice. But it is only my opnion. I hope my answer was helpful for You. Regards.
I’ve done mine a couple of times now and it keeps leaking from the rocker cover o rings. I haven’t used genuine vw ones though..so wondering if that’s my issue. They seem to be soft where as I would imagine they should be pretty stiff? Any help is appreciated
Yep original ones are more like stiff rather then soft, so you can feel some resistance while installing injectors. So the problem may be in: 1)quality of the seals. 2)high crankcase pressure (mostly because failing injectors copper washers, clogged PCV valve, bad pistons rings, failing turbo). 3)Too high level of the engine oil. So i think you replaced injectors copper washers? so we can eliminate that option of failure. Sometimes When can't trust the quality of sealing or gasket i just use some good sealant, but as you can see in the comments some people are against that. And I got a call from a man who replaced the gasket, o-ring, etc. on his 2017 seat alhambra and still has the same leak from the same places and he told me maybe he should have used some sealant and I said hmm ... maybe
@@HintSlice yeah I have been told before to use a sealant haha! Any particular brand ?I’m in the uk. & I have swapped out my pcv for an oil catch can, seems to be working fine. 2 things I’m thinking is the piston rings causing positive pressure or the gaskets..but like i said I fitted some that came with the new rocker cover and they wasn’t vw original lol
@@karlossmith3714 I'm usualy using Victor Reinz VR 70-31414-10 if I want to be sure that everything will be ok and also it dries faster then other sealants. And onother one is Elring EL 006.553 I have no problem with this one also, but it dries up a littel bit longer wich maybe gives you more time to ajust details. Sometimes I use copper Permatex for the cylinder head gasket etc. I think that is more like rocker cover leak rather than something is wrong with the piston rings. Any way whatever sealant You gona use, just remember degreasing surfaces is crucial moment in this job everything must be 100% clean! you can use some brake cleaner or carburator cleaner but carb cleaner is more agresive to ruber parts so be care full.
@@HintSlice okay. Something I have got is a rocker cover off an Audi a4 avant 2,0. It looks the same as mine without the long spout for the oil filler cap. The injector gaskets look the same but I know the injectors on the Audi are bigger. Does bigger mean as in thicker or is it just the nozzle that squirts the fuel is bigger?
Hi,i have the same problem with oil leakage,my car loose 0.5 liters oil every 1000 km ,i check everything and no other problem ! Can be from this gaskets leaking ?
If You clean everything from oil and then check again for the leak and engine oil appears on the top of the engine then yes it can be this gasket. You can watch humble mechanic video about oil leaks And also you can chek for the engine oil inside of the charge air pipe, maybe the turbo is failing?
...and to this day this car has no problems with oil leaking from this valve cover and injector seal, so yeah it was very bad idea ;) if you know how to use good sealant properly and what you need to do before you use it on the surface, then everything will be ok.

@HintSlice jakie byly objawy?

Hello, sir! Do i need to bleed the injectors by loosen up the nuts, even if i do it from the vcds with testing the fuel pump? Thank you?
Hi. No there is no need to loosen injectors nuts if You are using vcsd .

What about the pcv valve ??
What do mean? what about it?
Hy, was there any foult, that you this job?
Oil leakage was the reason to do this job and thats it

@@stelianciaturi8979, your's problably is burning oil.
Official Skoda workshop said 270 deg for injector clamp?
Thanks
with what did you clean the tips of the injectors ? :D
I don’t remember exactly, but maybe it was a plastic brush with plastic bristles
Is this the CRLB engine code?
Yes
silicon and new gasket is big no no , does not help at all
Thank You for your comment. Stay tuned for the new videos. Regards.
And God bless you my friend.
Silikon on gasket...omg you CANT do this!!! All work u done is uselles because of silikon on rubber gasket..

Just tell us your story of "omg you CANT do this!!!"
That engine looks horrible. You should change the oil every 10.000km.
True story bro 👍. Yep maybe even 7000-8000 km if driving mostly in the city✌️
Is this the CRLB engine code?
Yes
@@HintSlice then it is 8nm + 270 deg turn
