What to do when there's Fuel in the Oil? Don't Panic!! 

Prepering to change camshaft with new fuel injectors you gave me idea how to pull them out without buying special tools. 10/10 video👍

Hi Mr. Elbow, just wanted to let you know that I had the exact same issue with the same engine and tandem pump, but completely unmodified. I drained the oil to find about 8 liters of mixed diesel/oil in the catch can. I searched youtube for an explanation and found only this video. Rebuilt tandem pump with new gaskets and she's fine now. Funny thing, I found no other cases of this happening but yours, and I've been watching and learning from your chainsaw mill videos for years!! Small world :)

Love that your videos are all over the place!

Hugely rewarding to both locate the mechanism that failed (tandem pump seal) and recognise why it failed, (over enthusiastic lift pump). Pity you then found a worn cam - though I presume the engine had been running OK prior to the tandem event. With it all in bits the temptation to replace the engine must have been strong though you might have gained a few years use if you had "just" fitted the tandem pump seal kit and put the old engone back together...

Loved the last video, thought i can do that. Then this struck the fear of God in me

Love it. Keep em coming. Looking forward to seeing you refitting the engine. Good luck.

I found that whole thing fascinating. I've never gotten that deep into a diesel either. Best of luck with getting it back on the road.

Thank you mate for your interesting and informative video. Pleasure to watch 😉 greetings from Lithuania 🇱🇹🤝🇬🇧

Nice one mate, thanks for sharing your experience.

Does look worse than my wood stove 😆🤣👌 I admire your confidence and abilities and especially improvisation to the job at hand and inquisitive mind.... found this whole video extremely educational & well made and superb in detail, well done 👏 and happy motoring 👍

I did my injector seals on my 1.9 pd yesterday. My oil was slightly diesly and a bit of smoke on start up only. Thankfully I caught it early so my camshaft didn’t suffer. The injectors are easy as pie to get out, just twist them left -right a couple of times using a pair of grips on the front facing nut thing and they’ll pull out really easily. I think they sort of vacuum themselves in so the twisting motion breaks that seal, If only you knew before this video.

Thanks for posting, you are a brave mechanic! I have a big-end failed vehicle sitting, that even the lock-down has't given me courage/incentive to tackle.....Great work and film-making!

Such a brave repair.

Thank you, I believe you helped me narrow it down... Certainly isn't good news but at least I know. Great video!

Cam doesn't look bad at all compared to what i have seen in the past. It's normal wear, I would have just got the seal kit for the pump and called it a day.. next time you pull an injector out, twist the injector back and forth a few times and will pop out with almost no stress.

FYI veg oil dries out / makes rubber stiff. So if that seal that blew was in contact with veg oil and is made of rubber then that will probably be why, they get hard and stop flexing so cant do their job of sealing anymore, or at least it could be a contributing factor along with your lift pump setup.

Whilst joining this late, I am a tdi guru and had the us version of this engine BRM have you put it on the vagcom?

Is it because the oil perishes the seals on these units? I had a previous BOSCH VE mechanical injector pump rebuilt with Viton seals for this reason. 👍

Thanks man! I copied your PD injector removal technique, perfect. I too have lumps of wood hanging around my garage. I knew my hoarding would pay off one day 😊👍🏻🫡

Can the shaft seal be installed in the "wrong" way, not sure if I got it right as it was quite hard to put it in

Lots of great info here man....Thanks for sharing...;-)

Hi,mine also mixing oil and diesel what can I look at first and it wasn’t smoking at all but the hidling is like am on petrol and is polo tdi

Thanks i did rebuild on my a4 b7 2.9 tdi bre, but now is leaking oil and the car brakes, before rebuild it was leaking diesel and had no brakes, no sure what i did wrong, any advise?

Seen a few of your videos since i got my caddy, my understanding is that you are not a trained professional in this type of trade, for that sir i take my hat off in front of you, i am a level 3 mechanic and still learning things as i do my job, you have been able to fault find and identify major issues with no training, that is impressive, as for the internet mechanics telling you what is good and what is not, most have to try taking a rocker cover off then come on here and share opinions on how it should be done, kind regards🙂

شكرا جزيلا

12:30 nice way to remove them

Good video, did you strip down and inspect turbo , mines smoking a bit at the moment, can you analysis diesel in your engine oil?? Good video 👍

Says "don't panic" then has to buy another engine :)

I have a same engine and there is a diesel leak behind the engine i thing is from vacuum pump do you know for any another fuel lines behind the engine

Determine the cause of the fuel contamination. Possible reasons include: Faulty fuel injectors or carburetor: If these components are leaking, fuel may enter the cylinders and eventually make its way into the oil. Compression ring or piston issues: Problems with the engine's internal components can allow fuel to bypass the combustion chamber and mix with the oil. After addressing the issue, monitor the engine closely. Check the oil regularly to ensure that fuel contamination does not recur. If the problem persists or if there are signs of ongoing issues, seek professional assistance.

So which number 3 do I tighten first or both at once LOL @16:17

+FloweringElbow on 7:16 do you know the correct seal orientation?? i cant seem to figure it out how the new one should go back in....yaiks

So in other terms ,so the engine got destroyed by the main pump by using veggi oil ?

I've never seen an injector with 2 copper washers on...

Hello, I own a Kia Cerato 1.6 crdi 136 HP vehicle. My car is at 86,000 km. Diesel is mixed with the engine oil, the oil level is constantly rising. There is no problem in the operation of my vehicle, the idle is normal, there is no noticeable black or white smoke from the exhaust. It works immediately with a single start in the morning, there is no problem. The technician said it could be the DPF and he removed the DPF and cleaned it in the machine. The DPF was around 40% full, but it was still cleaned. But that was not the solution either. Engine oil level continues to rise in my vehicle. I think there is no problem with diesel injectors because there is no indication of injector failure. The vehicle engine has a timing chain. Could it be from the high pressure diesel pump seal? Or what could be the problem? Could you help? Have you ever heard of such a common problem for vehicles of this segment? Urgent. Thanks in advance

Hello. I have the opposite oil in the diesel. Is it from this pump? Thank you

Pull off the valve cover and look at the cams and lifters....from the brief sound of it running the lifters are toast and a known weakness of this engine.

Hi can this cause oil in fuel too

👊

The G goes between the E and the R. ;-)

Great video worth the wait(suspence)Your EGR valve is quite clean.My 1.9Tdi was smoking and lumpy on cold start then running well after 45 seconds/I last cleaned EGR when car was purchased nearly 3 years ago but happend to check it last week as on holiday and it was 85% blocked again so cleaned and car goes like a rocket again.You are not saying veg oil caused the failure but the fuel lift pump on the diesel circuit which is interesting.Can you list the pressure of the pump you eventually fit I suppose if you can find the pressure of the stock VAG in tank lift pump you should match it.There is also a modification people do to PD engines running veg they modify the in tank lift pump with a by pass hose ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-I_iB_VPatac.html so any excess fuel just stays in the tank they generally use this to improve the fuel feed on non Tdi engines like mine with a dedicated fuel injection pump(non PD engines)Last year when I was researching converting PD enines I did speak to a chap via eBay who said he has successfully converted several PD engines using a similar method.The lift pump situation on PD engines has been my stumbling block (switching and type of pump to use )hence the interest in yours channel.Keep it up.If you seen my channel I use a loop system on the feed to my Bosch pump(non PD)so the pump has less work to do as it is not constantly drawing fuel from the tank then sending unused fuel back again.I think If you get time to watch this 2toc video at 3mins 50 seconds he point out a loop system and I believe its on car with lift pumps? ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-fdH6T7jHnYk.html Does he use a lift pump with a pressure relief valve?do such things exist?I have seen lift pumps on ebay that are veg oil tolerent.Good Luck Great Channel.Once you find a cheap source (or free)you could look at running your heating syatem at home with a veg oil burner?Start on heating fuel then once warm switch to veg thats heated from the hot water via a heated fuel filter or just a heat exchanger.?Heating oil is about 50p per litre?

I need parts from the old engine want to sell them ?

they say "a stitch in time saves nine"

There's no need for that drain bolt to be that tight jesusu

Water leakage under headgasket

LOL but as I watched this I couldn't help but yell at the video NO, NO, STOP that is not it......I will add that if you have the Bentley Manual for your vehicle it will walk you step by step for any possible teardown or procedure. You will need the crank lock tool to do cam/TB work....tip do the timing belts slightly early and change the temp sensor and thermostat while coolant is out of the car and also replace the water pump and all of the rollers and one-time use bolts. Pity really that you live in the UK and with covid travel is difficult or I would be delighted to come help you work on your VW...I bet I have done 20 cam/lifter replacements in my day and it is very simple and the total kit here in the us is less than $500

Stop your cam is toast...look at the color of the cam bearings...see the copper!!!

TDI club. com signup and never again be spend all of this time troubleshooting.....Veggie and computer controlled injectors do not play well....

I think that it is HIGHLY IRRESPONSIBLE to encourage people to unbolt their engines at random and start poking bits of cloth in the holes. You are just asking for something to set on fire. What if you put the wheels back on the wrong way? VERY DANGEROUS!!!!!!!!!!!!!
