1.6TDI CAY (VW, ŠKODA,SEAT, AUDI) Cause End Elimination Of Oil Leaks
Вставка
- Опубліковано 9 гру 2022
- Quite often, the engine of the 1.6 TDI CAY, CAYC, CAYJ, CAYT, CAYY VW family has oil streaks coming from the valve cover, which not only spoil the appearance, but also cause a sharp burning stench in the car. The reason lies either in worn out seals or in a crack in the cover itself. This video discusses a special case of diagnosing a problem and eliminating the cause. Hope this experience is helpful.

Thanks for this. Had constant pooling around injector 3/4, replaced both seals and couldn't tell for the life of me where it was coming from. It's never the cheap problem!
Excellent video well made good camera work, very useful information
Vitaliy, thank you very much for this amazing and inspirative video.
Take care.

Hi mate beautiful video, really great job! Meanwhile i have a question i changed the injector seals everything is ok, but now i have oil leak under 2nd injector, its coming from injector sitting plastic cover. I wonder if can i change the plastic injector sitting without taking out the whole gasket cover like in this video? Can i take it by taking out injector only? I bought the plastic injector sitting "seal" but i wonder if i should start doing it at all. Im sure i have damaged it, because 2nd injector was stuck. Cheers!
Having seen you strugle to remove number teo injector,l think some high temp ceramic grease would be very advisable for the bottom section of the fuel injectors.
Not on the nozzle tip but above this area ,where you had the corrosion sizure issue with number two.
Great video, what type of grease did you put on the injections before your reinstalled them?
Thanks for the comments. I used lithium
Excellent video
What type of grease are you using for the injectors?
Hey Vitaliy Thank you for such a good video. Much help to me. I have an oil leak from injector number 1 stem, not from the whole cover.
Is it possible to just change the seal without removing cover? Best Regards
Thanks for the comments. You can just change the seal. To do this, remove the injector. In this case, I would also replace the seal of the second injector.
@@vitaliyburnashov537 Thanks, they are all looking a bit oily. Van is now 9 yrs old and done 75k miles. I might just do the lot, rocker cover gasket, injector seals and have the inlet manifold off for a clean too, as its never been done. Thank you
Hi, great video, i may have a leaky injector seal but i am also getting a bit of an oil leak out of my inlet turbo pipe which im hoping is excessive blow by from the crankcase breather , is it possible to replace the crank case breather in the rocker cover or is it a case of a new rocker cover?
Hello! Thanks for your comments! Are you sure it's the breather? Could there be a crack or O-ring on the pipe?
Hi Vitaliy, thanks a lot for this helpful video,but I have a problem with Golf 6 (2010 - automatic) with big white smoke. Can you advise me please to find a solution for this big smoke from my car . Thankt a lot again
Hello! Thanks for the comment! please tell me if you have any errors in the control unit?
Very helpful video, thank you for taking the time. Could I please ask the Torque Nm for the heater plugs and is there a specific sequence the the cam cover bolts ?
Thank you. I would not want to make a mistake, because from memory the tightening torque of the glow plugs is 10-12 Nm
I have a problem with engine oil leakage. I found it in the intercooler. Please note that I changed the gearbox twice and the problem remains the same. What is the problem? Please tell me the engine is 1.6 TDI 105 CV. Thank you.
did you have to prime the injectors with obd (computer diagnostics tool) before starting engine?
Yes, I used ODIS. The engine will start without diagnostic equipment. It will be necessary to turn on and off the ignition two or three times and turn the starter a little longer
Great video👏..whats the music by the way🤔
Thank you! Found it on the Internet without copyright, at least for now))
i believe you should renew injector hold down bolts to prevent later failure!
Absolutely right. The mounting bolts must be replaced with new ones.
and this engine is supposed to be able to do 700kkm?
Hey Bro
Great video!
I’ve replaced injector rubber grommets but still leaks. I’ve done your test and looks like leak is coming from stretch bolt seal… is that possible?
Also, after performing test by blocking crankshaft ventilation pipe I’ve started experiencing lots of white smoke and also smoking from flange between turbo and DPF.
Scanning no errrors and smoke from exaust pipe/flange comes and goes, not consistent.
Is it possible that by blocking ventilation pipe I’ve pushed some oil into turbo?
hey, I have this exact problem, did you manage to get to the bottom of this? Thanks!🙏🏻
Mine now appears to be leaking from under the stretch bolt below the clamp
Wow thank you…. I have my Passat 1.6 tdi b7 2011 outside for nearly one year, because oil was leaking somewhere next to dpf, and smoking badly, so thought maybe rocker cover gasket cause I couldn’t see where the hell it was coming from.. injector seals look fine but couldn’t get no 1 injector out for hours, bent crow getting it to move and once I got it out it’s sat there since. The copper washer is also stuck down no 1 hole. Well today I took my revenge and started to look at it 😂. How did you get the injector holes so clean ?
Will order a rocker gasket even tho the old one looks ok and try and remember how to put together again with the massive help from your video. Views might go up a few hundred 😂. Am I correct in thinking that there’s another liquid oil sealing gasket that needs to come off if removing the camshaft, it doesn’t look damaged as the black line seal seems ok looking, but worried that after fitting the rocker gasket and doesn’t stop the leak then it could be that possibly.
I’ve got Ross tec vcds cable / unlimited. But hoping I can get it to start after getting it put back together 🙏🙏
Hi! Thanks for the comment! I process the seat for the injector washer with an end mill (available for sale for different diameters of the well), then I wipe everything with a cloth and WD. If there were problems with extracting the injector, then most likely it will not work correctly after installation. It will have to be adjusted on the stand. All rubber seals are strongly recommended to be replaced. Their cost is nothing compared to the problems that may arise. The most likely cause of an oil leak is a gasket or mother valve cover. Unfortunately, it is necessary to diagnose on a car, according to the description it is difficult to give an unambiguous answer. I wish you a successful renovation. Everything will work out for you!
@@vitaliyburnashov537 Hello! My number 3 injector is stuck and my mechanic said that we must use an exctracting tool for injector. After we use that tool, do i need to take injector to a stand to be recalibrated ? If yes, why? What is happening there?
@@adrianionut7680 Hello. Your mechanic is right. If you use a puller, I strongly recommend that you adjust the injector on a bench. As a rule, an impact type puller is used, due to which the injector is subjected to loads and vibrations that are not present during its normal operation. I hope my explanation was clear)
@@vitaliyburnashov537 Thanck you very much for your explanation!
My Volkswagen vento 1.6tdi is having a same problem however the mechanic suggested to live with it as the leak is minor. What do you suggest?
Leakage will increase over time. In addition to the aesthetic state of the engine, toxic fumes will be added, caused by oil getting on hot surfaces. Personally, I would consider solving the problem. It's like dental caries: you go to the dentist earlier - it's cheaper and less pain))
Also ur oil will get contaminated due to dust from outside.. all these oil stays above the seal will go inside after the car gets stop
Injector 3 and 4 on my 1.6 TDI leaks a lot and ive noticed that the oil level have decreased. The car feels jerky when cold but no stench of oil inside the car or something. Do you the problem is the same ?
In your case, first of all, it is necessary to carry out diagnostics in order to find out unstable idling. Most likely the injectors need revision. On this motor they are capricious). Naturally, the leakage will need to be eliminated (as I understand it, we are talking about oil leaks, not fuel).
On the car in the video, oil was flowing, it got on hot parts and it stank of burning in the cabin.
Perfect!. Thanks a lot.
I have a slightly broken rocker cover for the same car. Can this be repaired or do I need to buy a new one?
Hi. I recommend replacing it with a new one. There is a high risk that due to thermal stress you will have a problem again.
there are alot of things you left out in this video. If anyone else is looking to do this job remember to check if you have springy metal o rings in your injector seals that connect on the top. I had to disassemble everything twice because I was missing one from the old seals and couldnt find it anywhere. Also replace copper washer, that goes on the injector. If yours are badly carbed up I recommend some pliers to gently remove the old ones and before you take it out completely do some circles close to the tip of the nozzle, that way you have an easier time putting the new one back in. and if you are wondering which way the copper washer goes in, it goes in the flatter side towards the injector. Also what the f is the torque spec for the fuel rail?
Is this a fairly straightforward job? I have a vw amarok with visible oil on rocker so needs replaced and looking to try tackling it myself
@@martin494563 I'm not saying it's a simple job. Took me 2 days of scratching my head and going back and forth between the parts store to get missing tools and getting the correct parts. If I had to do it again I would start of by checking which tools are needed, then I would disassemble the rocker cover. cover it up with some plastic or shoprag. Also cover every fuel line with some non residual tape. Next step would be to go the parts store (make sure you have another car you can borrow) and cross reference your old parts so that you avoid having to drive there multiple times. Compare your gasket thorougly as it may look the same on the surface but it may still be slightly different. I dont have the exact torque specs on me right now but I can fetch them on request. If you need any help feel free to ask lol :)
how do you clean the "tunnel" that the injectors go into ? (something bore?)
to clean the "tunnel" I used a cloth and WD, for the injector seat - a manual end mill (there is a set for different diameters on sale)
Hi bro I am going to do the same with my vento.oil leakage from tapped cover. So tell me one thing after adding seals do we need do service for injectors...kindly confirm
Hi. If there are no other problems besides oil leakage and if the injectors are removed by hand, without the need for a puller or hammer), then I do not see the need for their revision. Naturally, everyone should be put in their place.
you have to use new Copper seals. i would replace every seal of the injector, and if possible use an ultrasonic cleaning bath for them aswell
Absolutely right. The copper seals must be replaced whenever the injector is removed. What else was done))

I have issue with diesel leaking after replacing the injectors.. i have put new seals but still leaking. Any suggestions?
Hello. most often leaks from the return of the injector. I recommend thoroughly cleaning the surface and localizing the leak. Also, during installation, the O-ring could be damaged or simply defective.
@@vitaliyburnashov537 May I also add that I'd agree it's vital to inspect the O rings on the injectors and take off lines.. Don't forget to renew the copper washers on the tip of the injectors too
Do you need to bleed the fuel system?
preferably, but if there is no appropriate equipment, you can loosen the injector nut. usually starts on the third try)
I agree with the comment
I’ve got a problem where oil is leaking at the injector grommet area. Where can I find the grommet seals?
I advise you to buy the original ones from the regional representative of the VAG group
Greate Vidéo, but fucking musique !!
Are you sure problem was gasket not plastic valve cover? and better was replace all complet? injectors waschers, valve gasket and valves cover?
In this video, I diagnosed the exact cause. You can change everything in a row, but money does not fall from the sky for car owners)). Do you have any idea how much a valve cover costs? Why change it if there is no crack? There are times when it cracks at the seam, then another story. it all depends on the specific damage. I wish you successful repairs!
@@vitaliyburnashov537 How do you know if theres a crack in the cover? I have the same engine and both 1st and 2nd injector is wet at the bottom
@@idajosefin0121 Скорее всего нуждаются в замене резиновые уплотнения инжектора. Можно попробовать определить место протечки создав повышенное давление в картере двигателя. Снимите патрубок вентиляции и закройте чем нибудь отверстие как я сделал в видео. Попросите друга нажать на педаль газа короткое время. Скорее всего вы увидите выход небольшого количества карьерных газов с маслом в месте протечки. В вашем случае я ожидал бы вверх по инжектору. К сожалению по описанию сложно поставить однозначный диагноз.
Bad luck😂 all of mine are stuck, managed to get 1 loose, and one i can barely move back and fourth
sometimes a little luck is needed)
Hi any link for order
Hi, what would you like to order?
Did you have to bleed the fuel system after this?
yes, I just did this myself and I have a 2010 vw golf 1.6 tdi
I thing injectors after first tighten must be 270 degrese not 180...
it depends on the tensile tension of the bolts and material they are made of
2nm-8nm 3rd cikle 270 degrees
that engine sucks only problems with it and found many videos withm many ppl sayd the same , best diesel engine you can go is the same renault engine that dacia duster has and renualt clio and many nissan wear
